STATEMENT OF WORK

Requisition #290986

Title: Double-Shell Tank Integrity Test Facility

Revision Number: 1

Date: July 6, 2016

1.0 Objective

Washington River Protection Solutions, LLC (WRPS) as a prime contractor to the U.S. Department of Energy is issuing this Statement of Work (SOW) to design and fabricate partial tank sections of the annulus space of Hanford Tank Farm’s double shell tanks (DSTs).

The Tank Operations Contractor (TOC) manages twenty-eight carbon steel, double-shell, million gallon waste storage tanks located at the Hanford site in Washington State. Hanford’s DSTs were built in groups, commonly referred to as tank farms. The tanks store both radioactive and hazardous waste. To monitor and maintain their condition these tanks are inspected periodically through a comprehensive tank integrity program. The work of this SOW will focus on building a facility that allows WRPS to evaluate solutions for inspecting the bottom annulus (space between tank floors of the primary and secondary tanks).

The objective of this SOW is to design, fabricate, house mock-up DSTs, and host technology demonstrations. The facility housing the mock-up DST(s) will be used as a test facility for developing, testing, and evaluating non-destructive examination systems and their techniques.

2.0 Background/Introduction

Hanford’s DSTs are aging and monitoring of their integrity is crucial to how TOC maintains, operates, and estimates their remaining life. This SOW will construct and house a facility to enable WRPS to develop and test non-destructive inspection techniques and equipment which will allow WRPS Operations to inspect the most difficult area of the tanks – the primary tank and refractory region between the primary tank and secondary liner. To ensure successful implementation at Hanford’s tank farms, the facility must allow full scale testing of the inspection equipment. Previous tests with equipment have shown that getting inspection equipment into the refractory slots and through the bends/corners is very difficult, and a large portion of the tank bottoms have gone uninspected. The purpose of this facility is to allow development of systems and techniques that can inspect all exposed areas of primary tank bottoms.

3.0 Scope

Build and house a test platform emulating a small fraction of two DST annulus configurations. Figure 1 and Figure 2 below are photographs of a typical DST annuls space. The test platform (mock-up tank) will be used to evaluate tank integrity methods and equipment, therefore air channel replication is critical. One or two platforms may be manufactured, but each tank model must allow use of a 24” riser through which the inspection tool will be deployed.

The air channels are used to cool tank bottoms. The designs to be fabricated for this SOW are based on AY and AZ tank farm vessels. The following is a list of specifications to be followed for the design and manufacture of the test facility.
