Dear Mr. Knighton:
ANPP previously committed to implement a
program to reduce leakage from systems outside containment that could contain highly radioactive fluids during a serious transient or accident to as low as practical levels.
As a
part of this
- program, ANPP had agreed to submit a report to the NRC Staff which presents the results of the initial leak rate tests for the subject fluid systems.
The attachment to this letter is the report which details the leak rate test that has been performed.
If you have any questions on this matter, please contact Mr. W. F. Quinn of my staff.

RESULTS OP LEAKAGE MONITORING TESTING OF SYSTEMS OUTSIDE CONTAINMENT WHICH COULD CONTAIN RADIOACTIVE PLUIDS POLI OWING AN ACCIDENT PALO VERDE NUCLEAR GENERATING STATION UNIT 2

SUMMARY
The objective of the leakage monitoring testing program is to locate and minimize leakage from those portions of the Safety Injection System and the Post-Accident Sampling
'System which could contain highly radioactive fluids during a
serious transient or accident.
This testing ensures that leakage from these systems is maintained to as low as practical levels.
The leakage monitoring tests are performed on a
schedule of at least once per refueling cycle in order to meet the requirements of PVNGS Unit 2 Technical Specifications 4.5.2.e.4 and 6.8.4.a and NUREG-0737, Item III.D.1.1.
The leakage monitoring tests were performed on those portions of the Safety Injection System and the Post-Accident Sampling System outside containment which are likely to contain radioactive fluids following an accident.
The detailed results of these leakage tests are presented in Section IIIof this report.
The overall estimated leakage from the safety injection system is as follows:
(Please note that leakage estimates were not made for the sampling system which was inspected for indications of leakage in order to determine where corrective measures were needed).

Combined Safety Injection/Containment Spray (Trains A and B) 0.0134 II.
LEAKAGE MONITORING TESTING PROGRAM DISCUSSION This testing program is designed to identify any leakage from the applicable portions of the Safety Injection System (low pressure, high
- pressure, and containment spray) and the Post-Accident Sampling System.
For the Safety Injection System, the system is pressurized to greater than 40 psig at such time an inspector walks down the piping systems to identify any leakage from the potential leakage paths (i.e.,
valves, fittings, seals, etc.).
For the Post-Accident Sampling
- System, the system is inspected while it is operating in the normal sampling mode for each of the separate sample points (i.e.,
RCS hot leg, letdown
- line, containment radwaste
- sump, auxiliary building
- sump, safety injection lines).
The Post-Accident Sampling System gas sampler is tested by pressurizing the system with nitrogen gas and then checking for indications of a leak.
