Mr. W. A. Paulson, Acting Chief Operating Reactors Branch No. 5 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D.C. 20555 Gentlemen:
Subject:
Docket No. 50-206 Changes to In-Service Testing Program for Pumps and Valves San Onofre Nuclear Generating Station Unit 1

- 4) Letter D. M. Crutchfield (NRC) to R. Dietch (SCE), August 29, 1983, NUREG-0737, Reactor Coolant System Vents By Reference 1, Southern California Edison Company submitted a revised In-Service Testing (IST) program for pumps and valves for the San Onofre Nuclear Generating Station, Unit 1. By Reference 2, we notified the NRC of a change in the IST program. This is to advise you of two further changes, as discussed below.
- 1. In fulfillment of our commitment in Reference 3, valves SV-2401 through SV-2404 and SV-3401 through SV-3404 in the reactor coolant gas vent system (RCVS) were included in IST Procedure SO1-V-2.15, to be full stroke tested and fail safe tested at cold shutdown.
However, Note 15 to IST Procedure S01-V-2.15 made this testing conditional as follows:
"The Reactor Coolant Gas Vent System has been installed in the plant. This valve will be included in the program once the NRC approves the use of the system."

Mr. W.
September 11,19 9 Based on the schedule outlined in 10 CFR 50.44(c)(3)(iii) and the NRC's clarification in Reference 4 as to the intent of this rule, we have now concluded that (1) it is not necessary to obtain NRC's approval for purpose of testing the RCVS valves during cold shutdown, and (2) such testing must be initiated prior to Unit 1 restart.
Therefore, Note 15 is not relevant and will be deleted.
- 2. Table 2 of IST Procedure SO1-V-2.14 requires a quarterly vibration test for spray chemical addition pumps G-200A and G-200B, in accordance with ASME Code,Section XI.
- However, these are low, variable speed positive displacement pumps and the existing vibration monitoring equipment cannot meet the ASME Code,Section XI requirement to measure the displacement vibration amplitude, due to low pump speed. Therefore, an alternate vibration test that measures units of velocity rather than displacement will be substituted.
Revised insert pages for Procedures S01-V-2.14 and SO1-V-2.15, including a new Pump Relief Request No. 8, to reflect the two changes discussed above are enclosed herewith.
If you have any questions, please contact me.
Very truly yours, M. 0. Medford Manager, Nuclear Licensing Enclosure cc:

PUMP RELIEF REQUEST NO. 8 SYSTEM:
Containment Spray Hydrazine Addition COMPONENT:
Spray Chemical Addition Pumps G-200A, G-200B CLASS :
2 FUNCTION:
To provide hydrazine addition to containment spray TEST REQUIREMENT:
IWP-4510, At least one displacement vibration amplitude (peak-to-peak composite) shall be read during each in-service test.
IWP-4520(b), The frequency response range of the readout system, shall be from one-half minimum speed to at least maximum pump shaft rotational speed.
BASIS FOR RELIEF:
Existing vibration monitoring equipment cannot meet the Code requirement to measure the displacement vibration amplitude, due to a bandpass filter which deletes vibration input below 350 cycles per minute (350 rpm).
Pump speed is 77.5-155 rpm (variable speed).
Vibration probe sensitivity for available equipment is 120 to 9,000 rpm when measuring in units of velocity.
ALTERNATE TESTING:
Test in units of velocity using existing equipment at greater than or equal to 120 rpm. This will provide vibration monitoring at 1 times rpm where most rotating equipment malfunctions occur.

This valve Is a remotely operated hand control valve. A maximum stroke time is not required for this valve.
17 Per General Design Criteria (GDC)57, these valves are not required to be automtic and will not be seat.leak tested.
18 867 a, b, and c assume leak tightness of the Safety Injection System (Technical Specification 4.2.2).
Therefore, these valves will not be seat leak tested.
