Sheet No. 11 NOTES:
(For "B"
& "C" test results) 1.
Mcdification E-168, ccepleted April 6, 1978, removed the centainment isolation signal from the steam generator blowdown and sample valves; leak testing of these valves is therefore, "No longer required under Appendix J."
2.
This leak test is only required during refueling periods following Type "A" containment pressure testing.
3.
C. W. Fay to H. R. DentOn letter dated May 2, 1980, cc==itted to put the containment isolation signals back on the steam generator blowdown and sample valves but not test them per Appendix J.
4.
Electrical penetrations E58, E20, E22, and El were newly installed during Refueling (Apr. - May, 19911 3ecause cf the:r design, they
~
require a leak test (Type "3")
and will be tested regularly hencefdrth.
5.
Per commitments contained in C.
W. Fay to H. R. Denton letter, dated December 12, 1980, modification request M-730 added an autcmatic centainment isolation valve, inside containment,.to each steam generator blewdown line.
These valves were added during the October to* December, 1981, refueling cutage. Type "C" valve testing was also initiated.

Sheet No. 14 COMMENTS CU VALVES WITH LEAKAGE APPROACHING OR EXCEEDING 0.6 La AT STANDARD TEMPERATURE AND PRESSURE ORT 449 (1981 Refueling)
The check valve (2-C) in the service air supply line to containment was found to leak at 145000 sec=.
Upon disassembly, the valve was found to contain a buildup of foreign material. The valve internals were cleaned and the valve was reassembled.
The valve was retested and found to leak at 25 sccm.
(Licensee Event Report 81-014/OlT-0.)
ORT #69 (1982 Refueling)
The check valve (1-755B) in the CCW supply line to the "B"
reactor ecolant pump was fcund tc leak :n excess cf 1280C0 secm.
The ac::al leakage is not known as the required test pressure (60 psig) could not be achieved.
The valve was disassembled, relapped and reassembled. The valve was retested and found to leak at 1630 secm.
(Licensee Event Report 82-020/01T-0.)
CRT *34 (1983 Refueling)
The charging line check valve (1-370) was found to leak at 176000 secm.
Upon disassembly, the valve was found to contain foreign material. The valve was cleaned, relapped and reassembled.
The valve was retested and found to leak at 14 sccm.
(Licensee Event Report 83-009/OlT-0.)
CRT 462 (1983 Refueling)
During the type "C" test of the purge exhaust valves, valve 1C7-3212 was noted to be leaking air into the test volu=e (frcm its inflatacle seal).
Thus, the indicated test leakage of 470 seem is not valid, although the sealing performance of the valve was not significantly affected by the leaking seal as evidenced by achieving test pressure at a relatively low flow rate.
The valve was disasse= bled and the inflatable seal was replaced. The valve was retested and found to leak at 224 scem.
(Licensee Event Report 83-009/OlT-0.)
ORT #63 (1983 Refueling)
The purge valve LCV-3245 was tested and found to leak.in excess of 105000 secm.
Actual leakage could not be quantified as test pressure could not be achieved.
Upon disasse=bly, the valve was found to contain a buildup of foreign =aterial.
The valve was cleaned and reassembled. The valve was retested and found to leak at 10 sec=.
(Licensee Event Report 83-009/01T-0.)
