20555 Attention:
Mr. Albert Schwencer
Dear Mr. Schwencer:
PI: Temporary Change to Operating License No. NPF-2 Technical Specifications Alabama Power Company proposed the attached changes to Joseph M.
Farley Nuclear Plant Operating License No. NPF-2 Technical Specifications involving temporary waiver to Technical Specification 3.7.8.1 to add
" Provisions of Specification 3.0.4 are not applicable on a one time' basis commencing 10/26/78 and ending 11/1/78 at 1230 hours0.0142 days <br />0.342 hours <br />0.00203 weeks <br />4.68015e-4 months <br />." This waiver is applicable to the action statement of 3.7.8.1 as relates to surveillance requirement 4.7.8.1.b.2.
The Plant Operations Review Committee and the Nuclear Operations Re-view Board have reviewed the above proposed changes and have determined that the changes do not involve an unreviewed safety question as shown in the attached safety evaluation.
\\
In accordance with 10 CFR 50.30(c)(1)(1), three signed originals and thirty-seven additional copies of these proposed changes are enclosed.
If you have any questions, please advise.
Yours very truly, F. L. Clayto, Jr.

Temporary Change to Technical Specification 3.7.8.1 Action Statement 1
Requested One Time Only Change:
Add to Technical Specification 3.7.8.1 Action Statement the following words:
" Provisions of Specification 3.0.4 are not applicable on a one time basis commencing 10/26/78 and ending 11/1/78 at 1230 hours0.0142 days <br />0.342 hours <br />0.00203 weeks <br />4.68015e-4 months <br />."- This waiver is applicable to the action statement of 3.7.8.1 as relates to surveillance requirement 4.7.8.1.b.2.
, Background and Bases:
On 10/25/78 while reviewing test results relative to Surveillance Reqairement 4.7.8.1.b.2 it was noted that the filter penetration for the B Train of the penetration room filtration system was.07% filter penetration versus the
.05% filter penetration requirement of Regulatory Guide 1.52, Rev. 1, July 7, I
1976, paragraph C.5.c.
Based on these results the penetration room filtration system (B Train) was declared inoperable at 1230 hours0.0142 days <br />0.342 hours <br />0.00203 weeks <br />4.68015e-4 months <br />.an 10/25/78. The plant filter testing consultant is scheduled to be on-site 10/27/78 to follow correc-tive maintenance and perform the retest.
On 10/25/73 at 2235 hrs. the unit tripped. The unit is presently in Mode 3 with startup pending resolution of this problem.
The Train B filter penetration is.07% as measured by the DOP test for particu-lates and the Train A filter penetration is.02% for particulates as demon-strated in surveillance tests conducted in September, 1978. The charcoal test (i.e. Freon) was acceptable on both trains.
The penetration room filtration system is only required during the recirculation i
phase after a LOCA.
Repairs to the Train B filters are anticipated to be minor, only requiring adjust-ment of spring tension on the filter banks.
Nd disassembly-is anticipated.
Under these conditions Train B could be placed in service within 20 minutes and hence would be available in the unlikely event of a LOCA.
In view of the fact that Train B can be returned to service prior to being required if Train A experienced failure and Train B is presently capable of 99.93% efficiency the safe opera-tion of Farley Nuclear Plant Unit 1 is assured.
==
Conclusion:==
i This change will allow Farley Nuclear Plant Unit 1 to return to power and operate for the remaining period currently allowed by Technical Specification Limiting Condition for Operation 3.7.S.1.
The proposed change does i
(,
involve an unreviewed safety question as defined by 10CFR50.59.
