POINT BEACH NUCLEAR PLANT, UNIT 2 FACILITY OPERATING LICENSE DPR-27
SUMMARY
TECHNICAL REPORT OF TYPE A, B,
AND C CONTAINMENT LEAK TESTS
-4 In accordance with Section 15.4.4.I.D. of the Point Beach E
Nuclear Plant Technical Specifications and Section V. B.
of 10 2
CFR 50 Appendix J, the following summary technical reports are y
submitted on the Type A containment integrated leakage rate i
test conducted during the Sept. ember 1986 Unit 2 refueling i
shut-down.
Also included are the results of the Type B and C 3
leak tests conducted since the last Type A test.
These vere i
performed during the refueling shut-downs of April - May 1982, i
lj March - July 1983, September - December 1984, and October -
November 1985.
The Type A test was performed by the Bechtel Power Corporation for Wisconsin Electric.
We have reviewed and i
approved their report and have enclosed a summary report d
prepared in accordance with the format specified in ANSI /ANS
]
56.8 - 1981.
The complete report, which includes all 1
procectures, equipment calibrations, test data, and results will i
be retained by Wisconsin Electric and is available for NRC
?
review at the plant.

A routine, announced NRC inspection by Messrs.
F. Mauer and R.
]
Mendez was conducted during the performance of the Type "A" integrated leakage rate test.
No items of non-compliance or 5
deviations were identifed with the 1986 ILRT.

Page'2 Summary of Data
'The overall as-found : total time leakage rate of this Type A
~
test was 0.115%/ day at the 95% upper confidence level.
This is 57.2% of the allowable leak -rate..The: leak rate reported
- includes'a 0.013%/ day penalty for non-standard valve
~
. alignments, containment-volume changes, and nitrogen additions a
to the containment. -
The overall'as-found leakage of the Type B and C tests conducted.during:the.1982 refueling outage was 145,744 sec per minute.orl63.4% of 0.6L described in Section III.C.3 of
' Appendix J'to 10 CFR 50,.
After. repairs, the overall leakage
. rate was.10,474 sec per minute or 4.5% of 0.6L,.
.The~overall as-found leakage of the Type B and C tests conducted during the 1983 refueling outage was 99,390 sec per minute or143.2% of-0.6L.- After repairs, the overall leakage
. rate was 12,608 sec per, minute or 5.5% of 0.6L,.
The overall as-found leakage of the Type B.and C tests conddcted during the 1984 refueling outage was greater than
.(not quantifiable) 19,976 scc per minute or 8.7% of 0.6L After repairs, the overall leakage rate was 14,066 scc p8r.
minute or 16.1% of;0.6L,.
The.overall as-found leakage of the Type B and C tests conducted during the-1985 refueling outage was greater than (not quantifiable) 200,770 scc per minute or 87.3% of 0.6L
~
'After repairs,'the overall leakage rate was 12,328 sec per,.
minute or 5.4%-of 0.6L',,
Enclosed are summary l reports of the 1986 Type A test and the
~
Type B and C tests between the April 1982 and October 1986 ILRT'S.
The summary-of the Type B'and C tests includes all of the test data obtained during and between cach of the refueling outages.
Also included with the Type B.and C results are comments concerning those penetrations whose leak rate approached the 0.6L, limit.
Very trul
