CONTAINMENT LEAKAGE TESTING LACROSSE BOILING WATER REACTOR
1.0 BACKGROUND
in a letter dated December 21, 1976, Dairyland Power Cooperative (DPC) provided information to the NRC regarding certain previously requested exemptions j
from the requirements of 10CFRS'0, Appendix J, Containment Leakage Testing.
2.0 INFORMATION REQUIRED TYPE C TESTING OF ISCLATION VALVES USING WATER AS A TEST MEDIUM IN LIEU i
2.1 OF AIR DPC's letter of Dece:nber 21, 1976 indicates that several isolation valves are tested with water as a medium in lieu of air and that the test results are l
I analytically converted to equivalent air leakage.
The isolation valves involved are:
1 De:sineralized Water i
2.
Condensate Demineralizer to Seal Injection Reservoir Make-up Line j
3 High Pressure Service Water 4.
Retention Tank Pump Discharge (Control Valve) 5 Decay Heat Start-up Water Removal
- 6.
Shutdown Condenser Vent to Off-Gas
- 7.
Primary Purification Resin Sluice
- 8.
Alternate Core Spray
- In order to determine the acceptability of the conversion method, you must
- However, provide justification for the validity of the water-to-air correlation.
since the leakage involved is generally quite lov and also since the leakage path characteristics are essentially unpredictable, it is extremely difficult to l-correlate water leakage to equivalent air leakage accurately.
To date, no I
l acceptable correlation has been demonstrated.
L Only those which can not be water drained..
1
. ~.
f Nevertheless, hydrostatic testing of these valves may be found acceptable because there are some systems which are designed to remain intact and liquid-filled following a postulated loss-of-coolant-accident.
For these systems, testing with water as a medium is more appropriate than testing with air or nitrogen since it more closely approximates the post-accident environment.
If hydrostatic testing of these systems is to be exployed, justification must be provided that the available fluid inventory is sufficient to maintain a water seal on the isolation valves during and following an accident based on the water leakage-rate limit of the test.
~
Provide either an acceptable basis for' utilizing a water-to-air correlation or a justification that the affected systems will remain intact and liquid filled post-LOCA.
