ABSTRACT

This report describes the successful decommissioning of plutonium- contaminated equipment used for weapon component fabrication and Inspec­tion at the U. S. Energy Research and Development Administration Hanford Plant In Washington state. Special materials, techniques, and equipment were employed during the course of the decommissioning program. Most significant was the development and design of large, double-wall fiber- glassed plywood boxes for long-term (20-years, minimum) retrievable stor­age of the contaminated equipment 1n underground transuranic waste trenches.

. " INTRODUCTION

The Division of Military Application (DMA) decommissioning program at Hanford was authorized through the U. S. Energy Research and Development Administration Albuquerque Operation Office (ERDA-AL) on November 12, 1973. The program wasdlrected by the Richland Operations Office (RL) with management by Atlantic Richfield Hanford Company, utilizing the onsite architect engineer (A-E) and cost plus fixed fee (CPFF) construc- 1 tlon service contractors. The DMA equipment and support facilities required for the RL production (KK) programs were retained and trans­ferred to that account.

This Report summarizes the results of the program with the details of the scope, of work, responsibilities and removal techniques delineated for possible application to other related ERDA programs being considered for the future.

* OBJECTIVES

The scope of the decommissioning program provided for the following objectives:

• Removal of all Division of Military Application (DH) fabrication and inspection hefd in standby status 1n the 234-5 Z Building.

• Disposition of all contaminated equipment and materials removed by packaging for. safe 20-yfear retrievable storage.

t Reclamation of salvageable materials and equipment for use onsite by other ERDA contractors. - .

• ■ Restoration of cl eared-out areas for other planned Richland Opera­tions Office programs.

SUMMARY

Decommissioning of the DMA*standby equipment and facilities was completed, with minor exceptions, on May 25, 1976, and within the estimated cost.The physical work was completecl over a 24-month period at final cost of $2,134,137.

The majority of the plutonium-contaminated equipment was loaded 1m>o special Hanford developed fiberglass-reinforced polyester (FRP) plywood boxes for 20-year retrievable storage 1r, a separate, earthen transoranlc,

.waste trench. Lead shielding, Instrumentation, and mechanical equipment With an'acquisition value of $120,000, was salvaged and transferred to the Battelle-Northwest(BNW) central equipment pool for onsite use by other ERQA-RL contractors*. A total of 61 boxes of varied size and type, with a'gross volume of 78,781 cubic feet, a net weight uf 328,950 pounds, and containing 5,591 grams of residual plutonium were transferred to the special DMA trench for 20-year retrievable storage. The total does not include sevien boxes of equipment from the 234-5 Z Building development laboratory which had been used In technological support of the weapons production program at Hanford. The cleared out areas, after decontamina­tion, painting* and renovation, are being utilized for other.ERDA-RL sponsored research and development programs.

HISTORY

The DMA equipment and facilities, located in the 234-5 Z Building at Han­ford, were used from 1949 to 1965 for the fabrication, inspection, and packaging for offsite shipment of plutonium weapons components. The DMA equipment occupied approximately two-thirds of the available produc­tion floor space. The facilities consisted of two separate production lines (RMA and RMC) each equipped with a central conveyor system tied into glove boxes with capability for casting, ingoting, machining, briquetting, shearforming, phase stabilization, product inspection, radiography, storage, packaging and loadout. From 1965, the majority of equipment was on standby status, although tied Into the building services for safety and contamination control. Some of the inspection equipment was transferred ta.other contractors onsite and certain equipment retained in support of ongoing plutonium production (Kip programs. The cost of continued surveillance, services, and monitoring of “the remaining, facil­ities, along with gradual deterioration of glove box gloves and contam­ination control (plastic) barriers, led to the ERDA decision to remove and package the inactive equipment for safe, retrievable underground storage.

’ #Atlantic Richfield Hanford Company (ARHCO), a prime contractor at Hanford, was assigned management responsibility for planning and execution of the DMA*decommissioning program.

DISCUSSION

Work Authorization

Various discussions were held between ERDA-RL and ARHCO from 1970 to 1973, on several proposed alternates for disposal of the inactive DMA

3 ARH-ST-141

facilities. Two cases considered for preliminary engineering studies were:

• Continuation of 1n-place storage until special new facilities could be provided for dismantling and packaging the equipment in containers suitable for the then proposed salt mine repositories.

• Prompt removal and packaging of equipment 1n approved containers for 20-year retrievable storage in earthen trenches at Hanford.

The first alternative was ruled out since salt mine technology had not been fully developed, was long-term, and required a high (about $3,000,000) capital investment. The latter case was selected as an interim solution that could be accomplished in a relatively short period of time at less than one-third the total cost of the salt mine storage alternative.

Initial funds of $200,000 to proceed with the retrievable storage pro­posal were authorized to ARHC0 by ERDA-RL on November 26, 1973.

Work Plan and Procedures

The initial engineering study on interim, retrievable storage that was submitted as an alternate for decommissioning of the DMA facilities was modified and expanded to include ERDA-RL directive requirements and for­mally issued on April 26, 1974, as the official work plan document (reference 1) for management and execution of the program.. The document specified ARH-3032 (reference 2) as the official guide for handling and storage of radioactive waste. Special procedures, for handling and dis­posal of hydraulic fluid and oil for example, were prepared separately by ARHC0 as . equi red (see Appendix A).

The preparation of detailed procedures for removing individual glove -bokes and associated equipment was assigned to the onsite architect- engineer contra .tor, Vitro Engineering Company, with technical guidance by ARHC0. These procedures, which included applicable checklists, are enumerated in references 3, 4, and 5.

Organization

Atlantic Richfield Hanford Company was assigned prime responsibility for the conduct and execution of the decommissioning program, with assistance from other onsite contractors where required. Vitro Engineering Company provided design and related services while physical demolition and removal was assigned to the onsite construction service contractor, J. A. Jones, Company. Photographic and graphics services were obtained fcom BattelTe- Northwest. An organizational chart delineating lines of communication and prime responsibilities is shown in Figure 1. See Appendix B for all figures.

4 ARH-ST-141

The primary design work requested of Vitro Engineering in early May, 1974, was for reliable storage containers to handle the large glove boxes and equipment without the need for dismantling and risking loss of contam­ination control. Because of the high cost and scarcity of steel ai the time, other materials of construction were evaluated. In view of thp approved us,e of fibergiassed, single-wall plywood boxes for containing transuranlc waste at the Rocky Flats Plant, it was*decided to evaluate the same basic concept for application to the Hanford design. As a result, modular, double-wall boxes of high structural integrity were developed at Hanford'using pre-fabricated FRP panels manufactured by Cor-Tec Inc'. and de'picted in figures 2, 3, and 4. Other approved containers weve utilized as conditions dictated and included Hanford steel tvDe I and II. Rocky Flats FRP type, and 55-gallon alkyd-coated steel drums, as shown in figures 5 and 6.

•*- • * , * ,, *.

Other design work by Vitro Engineering included architectural and struc­tural additions or modification, shoring requirements to protect low-1oad floor areas while moving heavy equipment, and material specifications.The specification for fabrication of the FRP plywood boxes, for example, is provided in reference 6 . The drawings that detail the FRP plywood boxes and lifting frame design are listed in Appendix C.

Materials and Special Equipment

Certain specialized equipment, along with routine materials required for handling potentially-contaminated equipment, were utilized in the con­duct of the decommissioning program. Plastic (polyethylene and polyvinyl chloride) sheeting was employed for fabrication of temporary containment enclosures (greenhouses) for plutonium contamination control. Cloth- backed taped was used for sealing joints and packages. Special poly­ethylene sleeves were utilized for containment while disconnecting glove boxes from the main conveyors by the "horsetailing" technique described later.

* ■ jf

A 50-50 mixture of diatomaceous earth (Dica-Sorb ) and commercial, oil - absorbing flonr sweeping compound was used for absorbing and converting contaminated oil and hydraulic fluids to a non-liquid form for contain­ment in polyethylene-lined 55-gallon steel drums prior to boxing and transferring to the transuranic storage trench.

Demolition and Removal

Following completion of design and procurement of essential material?, along with approval of work procedures, physical removal of equipment was Offi­cially started by J." A. Jones. Construction Company on May 28, 1974. A plot plan of the areas requiring equipment removal is shown in figure 7.

Work was initiated in the inspection area (room 192) since this was con­sidered the cleanest relative to the degree of contamination inside the glove box and the amount of residual plutonium. Gauging, polishing, radiography, and storage of plutonium weapons components were the only activities performed in the area, leaving the glove boxes contaminated but relatively free of plutonium residues.

All necessary permits, covering planned work sequence with detailed instructions and guidelines, were prepared and issued prior to the start of work for safety and contamination control. This included (a) radiation work procedure (RWP), (b) fire control permit for weld­ing and cutting, and (c) excavation and core-boring permits. These permits were supplemented with special procedures where unusual condi­tions or need for extra safety precautions existed. An example of this was a procedure, for the removal and transfer of the hydraulic fluid and oil from the mechanical equipment for absorption in a diatomaceous earth mixture to assure long-term containment. Other guidelines were firmed up, including limits established in the ERDA Manual Chapter 0511 for solid transuranic waste disposal of 10 nanocuries per gram activity where measurable. This was later modified to categorize any equipment or materials exceeding one (1) nanocurie per gram (where surveyable)-as transuranic waste to be conservative. This was equivalent to 2,500 disintegrations per minute as read with an alpha scintillation instrument such as a portable alpha meter (PAM or Poppy). If a surface were painted or inaccessible for survey, the item was considered poten­tially contaminated and classified as transuranic waste.

All glove boxes and equipment were counted with a portable sodium iodide (Nal) gamma instrument to determine residual plutonium content prior to performing any physical work as pictured in Figure 8 . Clean­outs were made to reduce the quantity to as low as practical value without dismantling equipment. A 500 gram maximum plutonium value was established for transuranic storage of an individual glove box.Good recoveries were obtained from several qlove boxes with a final total recovery figure of approximately 3,000 grams.

Using these guides, most of the equipment and materials external to the glove box were salvaged for use by other onsite contractors. Lead shielding on glove boxes was removed for salvage/ and to reduce equip­ment weight and containment box structural requirements. Less than one percent of the lead removed was found to be contaminated.

Removal of auxiliaries such as electrical services, piping, lead, or lead-glass shielding, and instrumentation was performed initially to strip the glove box and general area to the bare minimum. Differential pressure gauges were retained to maintain and monitor glove box negative continuously. Combustible materials such as rubber gloves, plastic bags, and the like were removed from glove boxes, however, and trans­ferred to the Z Plant Operations scrap incinerator for residual pluton­ium recovery.

Plastic greenhouses and sleeves for containment and "horsetailing" glove* boxes from main conveyor were used extensively as shown in figure 9.All glove boxes were maintained on a one-half to one-inch water negative until physically removed. If a glove box could not be loaded into a storage box within 24 hours it was connected to auxiliary ventilation using flexible hoses as depicted figure 10. All box loadings were made outside of the building under ideal weather conditions relative to wind and precipitation. After closure of boxes, the lid was sealed with fiberglass and,resin and transported by flat-bed truck to trans­uranic trench.

Records* and' Reports

Accurate and detailed records were maintained throughout the decommission­ing program for historical purposes and accountability. Special forms were prepared for (1) itemizing box loadings, (2) nondestructive assay, (3) disposal and transfers, and (4) equipment and plutonium account­ability. Transuranic storage maps were maintained to show storage arrange ment of boxes in trahsuranic trench. Examples of the forms used are shown in*Appendix D. Monthly reports, providing detailed description of methods and techniques employed in decommissioning, along with tabulation of cost* plutonium accountability, and other statistical data, were pre­pared and issued by ARHCO. In addition, quarterly summary reports with photographs and special procedures, as well as statistical summaries were compiled by ARHCO and formally assembled and issued by ERDA-RL.The records and reports provided a chronological history and preserved significant data applicable to other planned decommissioning programs.

The quarterly reports that were issued contain all significant informa­tion and photographs relating to decommissioning procedures, techniques, and equipment. Consequently the step by step methods and detailed des­criptions are not repeated in this report. The quarterly reports have been provided with ARHCO document identification numbers for reference purposes as listed,in references 7, 8, and 9.

A composite-speech article report (reference 10} was also prepared covering initial DMA and related decommissioning programs at Hanford for presentation at the 1975 American Nuclear Society winter meeting in San Francisco, California.

Transuranic Storage

All boxes containing the removed DMA equipment were placed in a single• earthen trench that measured approximately 24 feet wide by 1,000 feet

long by 13 feet deep. The trench is located in the Hanford 200 West Area burial -garden 218rA-3A. The first box was located six feet from the adjacent box to permit easy recovery in five years to analyze the effects ,,of soil on the fiberglassed plywood. All other boxes were located with a '■'minimum spacing of one toot, except where the residual plutonium exceeded

7 ARH-ST-141

250 grams, which necessitated three feet minimum spacing from otner containers. Single wall fiberglassed plywood boxes of the Rocky Flats type were stacked two deep to reduce earth load on the bottom box.

' * *total of 61 boxes of various types and sizes were stored in the trench

from the DMA and related weapons decommissioning programs. Additional spacing remains for storing other containers of obsolete, plutonium- contaminated equipment being removed from non-DMA laboratory and process areas in the 234-5Z Building. A tabulation of all DMA boxes *-ransferred to transuranic storage, along with a residual plutonium content, volume, and weight is provided 1n figure 1 1.

Cost Summary

The total cost for the decommissioning program was $2,134,317 compared to $1,960,000 estimated at the start of the program. Rescoping of the program in 1975 to include additional equipment and conveyor line removals increased the original estimated cost by $200,000 which was approved and budgeted. This work was completed at a lower cost to provide a net underrun of approximately $25,000, not including-the estimated

' $120,000 value in salvaged equipment and materials*.

A tabulation of costs by quarters and participants is provided in figures 12 and 13.

Facility As-Built

The service for detailed as-builting of the decommissioned areas was pro­vided jointly by Vitro and ARHC0 design personnel . The as-built work was performed over a five month period at a cost of $44,317. In total, 1,661 drawings were reviewed, 1,338 drawings voided, and 239 drawings revised. No attempt was made to as-built remaining existing facilities in the affected areas, such as duct level ventilation. Only those por­tions affected by the DMA removal work were as-built to the point of removal. If a portion of an electrical control or ventilation system were removed, that portion was delineated on drawings by cross-hatching or ruling out. An area arrangement plan of the facility with equipment removed and relocated is shown in figure 14 for comparison with facil­ity at start of program as shown in figure 7.

TRANSFERRING HYDRAULIC FLUID AND OIL

General

TKls procedure provides for transferring of radioactive hydraulic fluid and oil to 55-gallon drums for disposal. The liquids to be disposed of are those associated vith the 'Division of Military Application (DMA) equipment to be removed from the 23*1-5 Building. Reservoirs to he transferred are listed in table 1. Fluids, not requiring transuranic burial, may be disposed of using 30>gallon drums or any other suitable metal container.

Safety

Plutonium contamination is one of the anticipated hazards. Care must be taken to prevent the spread of contamination.

The* fluids themselves present tvo possible hazards. Some of the liquids are flammable, and appropriate precautions should be observed when handling them. Spillage may cause slippery floors, as veil as possible spread of contamination, and should be avoided.

Site preparation should be designed and carried out to allow safe and efficient operation. Appropriate preparation of the area is left to the • discretion of supervision in charge of transfer operation.

*

NOTE: ARH- 3 0 3 2 sets limits on plutonium content and activity ofmaterials to be buried at the transuranic burial site, in accordance vlth 20-year retrieval criteria. No more than 200 grams of plutonium may be buried in a 55-gallon drum.Laboratory results should therefore be received and evaluated before the fluids are transferred to the drum. The quantity of plutonium to be transferred to the drum should be estimated and verified as being less than 200 grams before proceeding with the transfer. *

Fluids of the same type may be mixed in the drums. Hovever,care must be taken to note total plutonium transferred to anyone drum. ' ,

• Accurate records of all transfers must be maintained. A data sheet is provided vith this procedure.

Procedure

1. Prepare area for transfer as supervision directs. Use absorbent paper to soak up any spills.

2. Obtain 55-SaU-on drum for liquid transfer. Inspect drum protectivecoating to insure integrity. A standard plastic drum liner should alsobe utilized.
