l SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 24' TO FACILITY OPERATING LICENSE NO. NPF-2 AND TO AMENDMENT NO.
6 TO FACILITY OPERATING LICENSE NO NPF-8 ALABAMA POWER COMPANY JOSEPH M. FARLEY NUCLEAR PLANT, UNITS NOS. 1 AND 2 DOCKET NOS. 50-348 AND 50-364 Introduction On July 30,1981, at 12:50 AM, while performing surveillance tests on diesel-generator 1C it was determined that the jacket cooling water has been introduced into the number 11 cylinder. At this time, diesel generator 1C war declared inoperable and the existing Technical Specification 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> ACTION statement was invoked. After exceeding the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> ACTION statement, both Units 1;and 2 must be placed in HOT STANDBY.
Investigations revealed that an excess of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.would be required to return diesel generator 1C to OPERABLE status. By
. letter dated July 31, 1 981, the licensee requested a one time exception to permit plant operation up to six days in additiun to the three days allowed by the Technical Specifications (nine days total) to allow repair of diesel gener-ator 1C without shutting down the Unit 1 and Unit 2 facilities.
The Technical Specifications also state that during the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> period when a diesel generator is declared inoperable, the remaining diesels must be started every eight hours to verify their operability.
Since this would amount to approximately 120 combined starts for the remaining d.iesels, the licensee has-requested that the period be. increased to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> during this one time repair because accelerated wear and degradation might occur due to the large number of startups.
The above requests were evaluated in our Safety Evaluation report dated July 31, 1981.
This report is attached to License Amendment No. 21 to NPF-2 and License Amendment No. 3 to NPF-8. However, repairs to the diesel prove ~d to be more extensive than original expectations. By telecopy dated August 7,1981, a further extension of the Technical Specification outage allowance by six addi-tional days was requested. This would allow a total outage time of fifteen days to complete the repairs of the more extensive damage found in diesel generator 1C.
This extension time results in a very tight schedule which might require further extension.

.s -Discussion and Evaluation The staff met with the licensee representatives and the diesel generator vendor. representative in Bethesda, Maryland, on August 3,1981..At this-meeting the licensee presented its diesel repair proposal which basically results in a major overhaul of diesel 1C. The staff requested details of tests to be _ conducted following completion of the repairs.
The licensee has been working on a 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> a day schedule, but was unable to complete the maintenance within the six additional days previously granted.
Not only did they have several technical problems to solve during the overhaul, but also the air traffic controllers strike slowed the supply of spare parts.
The staff has reviewed the licensee request for an additioral six day extension which included a safety analysis and details of the tests to be done following completion of repairs.
Summary The staff has determ.aed that the basic concerns and conclusions of its Safety Evaluation Report issued July 31, 1981 are not significantly changed by the additional six day extension. The licensee considers the emergency on-site power system and the off-site power system to be highly reliable at this time. Also the licensee is placing significant management attention to this problem.
In a telephone conversation of August 7,1981, Mr. R. P.
Mcdonald of Alabama Power Company advised fir. T. M. Novak that he would review the personnel manning to insure all operators are properly trained and motivated to handle any emergency which might require diesel IC to operate.
Furthermore, a good portion of the six day extension would be used for the diesel test and run-in program. APCo committed that 11 the diesel was under test and an emergency occurred, the diesel could e.nd would be utilized.
Therefore, the staff concurs with the additional six day extension as requested.
Environmental Consideration We have determined that the amendments do not authorize a change in effluent types or total amounts nor an increase in power level and will not result.
in any significant environment impact.
Having made this determination, we further concluded that the emendment involves an action which is insignificant from the standpoint of environmental impact and, prusuant to 10 CFR 551.5(d)(4),
that an environmental impact statement of negative declaration and environmental impact appraisal need not be prepared in connection with the issuance of these amendments.

. Conclusion -
- We have concluded, based on the considerations discussed above, that:
(1)
. because the -amendments do 'not-involve a significant increase in the probability --
or' consequences of accidents previously considered and does not_ involve _ a,signif-icant hazards-consideration,. (2) there is reasonable assurance that the health and safety of theLpublic will_. not be endangered by pperation in the proposed
- manner, and _(3) regulations and the issuance of these-amendments sill not be
. inimical to the common defense and-security or to the health and safety _ of the pu bl ic, Date:
