1.0 INTRODUCTION
JUSTIFICATION REPORT
POWER OPERATED RELIEF VALVE
Control Components International will supply a total of twelve power operated re 1 i ef va; ~es ( PORV 1 s) to the Duke Power Company. A 11 of the valves supplied are Self Drag models. These valves will be used in two Duke Power PWR plants: McGuire Nuclear Station and Catawba Nuclear Station. There are two units at each of these plants and each unit uses three CCI PORV valves. The table below lists these plants and the corresponding PORV's.

2.0 DESCRIPTION OF BASIC VALVE MODEL
Drawing Number
118760 921101010
The CCI PORV is a 3x4 globe style body, with interpolated pressure class rating of l,534 pounds. The valve operator is a double-acting piston airoperated cylinder. A pair of springs are above the operator pis~on to close the valve in the failed air mode. Th~ operator is, in turn, controlled by two 3-way solenoid valves which are provided by the Duke Power Company. The main internal components in the valve are the plug, seat ring, and disk stack. The plug is 2~ inches in diameter, and the material is ASME SA 637-GR-688-2. The seat ring is 316 with Stellite inlay on the seating surface. The disk stack consists of many disks, brazed together, and made of 410 Cres. Flow through the valve is restricted by the disk stack by varying the number of turns and the area of the flow passages on the individual disks. As the valve opensv the plug comes off the hard seat and travels very quickly up the disk stack bore (opening time for the ~ inch stroke is less than two seconds). Fluid enters the valve body, flows from the outside of the uisk stack into the disk stack bore area, past the seat ring and out of the valve. Drawings and parts lists of the valve assembly, the body assembly1 and the actuator assembly are included at the end of this report (Attachment 1).
3.0 SELECTED TEST VALVES
The valve selected for the EPRI tests is identical (see Section 4.0} to the PORV's supplied at the Catawba Nuclear Station. It is valve serial number 18789-1-1 and part number 921101010. Drawings for this valve may be found in Attachment l.
4.0 DESIGN VARIATION BETWEEN TEST VALVE ANO PWR PLANT VALVES
All valves supplied are identical in fit, form, and function with the following exceptions or clarifications:
4.1
4.2
There were two methods of bonnet manufacture employed: One machined of solid bar material and one of welded construction.
Each valve has a custom fit trim to account for variations in manufacturing tolerances.

4.3 Buttweld details are different between orders supplied to date. This effects stress relief methods in welding into plant piping.
4.4 Each order was designed and manufactured to different code requirements. The first order was ASME Section 3, 1971. The second order was ASME Section 3, 1974.
In the opinion of the CCI Engineering Department none of the above differences will have any effect on the performance of the valve tested compared to those valves in PWR plants.
5.0 CONCLUSION
EJV/js
The test valve selected is virtually identical to those supplied by CCI for use in the PWR plants •. The PORV valve listed in Section 3.0 of this report is an excellent representation of all CCI valves supplied for this application.
