JUL 8 1931 Station Blackout Station blackout is characterized by the loss of both offsite and emergency ac poder for an extended period of time. Core melt can occur if the turbine-driven auxiliary feedwater system fails or if the reactor coolant pump seals fail subsequently because of lack of cooling.

The sequence probabilities noted in Table i represent estimates for the next 13 days of operation with only 4 diesels available. As indicated in Table 1, the total probability of a core melt associated with a Station Blackout during the next 13 days is approximately 3 x 10-3 This one time risk is considered acceptable.

An explanation of the core melt probabilities follows:

There has been one loss-of-offsite power event in 4 years of operation or a point estimate of 0.25/ Reactor Year (RY) which is consistent with generic results.

Since we are concerned about 13 days with only 4 diesels, the probability of loss of AC is 0.25 x 13/360 = 0.009 during the 13 days.

Based on Westinghouse analysis of loss of all feedwater, the core would begin to uncover in about 4000 seconds and would be completely uncovered in 5000 seconds.

Thus, if offsite power is not restored in about 1-1/2 to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months (assuming no emergency power), core melt could occur. An estimate of the probability of not recovering of fsite power in 1-1/2 hours is 0.22/ demand (D).

Core melt would probably be well underway with the postulatad conditions in about three hours.

The probability of not restoring offsite power in the 1.

hours is estimated to be 0.15/D. Sufficient information is not available i

to estimate the time for RCP seal failure in the absense of any cooling.

While diesel generator 1C is out of connission, the emergency ac poutr supply consists of four diesel generators which power emergency buses for Units 1 and 2.

Alabama Power Company's connitments concerning procedures for loading the diesels is discussed in another section of this report.

A minimum of one emergency bus is required for each unit. A faulted condition resulting in the loss of 3 out of 4 of the diesel generators would result in one unit not having an emergency bus available.

Based on data obtained since liarch 1981 and during 1977 and 1978, the point estimate of diesels failing to start given a loss of offsite power is 16/148 = 0.11/D. This unavailability is above generic experience.

The common cause failure of a second diesel to start given the failure of one diesel is.05 to 0.16.

We will assume 0.16/D.

Similarly, we arbitrarily assumed the probability of a third diesel to start given the failure of two diesels is 0.3/D.

Thus, the unavailability of 3 out of 4 diesels is 4 x 0.11 x 0.16 x.3 = 0.20/D which is about 5 times higher than the probability of random failures of 3 out of 4 diesels.

4 JUL 8 1931.The unnvailability of 'the turbine-driven AFW pump is 0.06/D based on' operating experience since 1977 (two failures out of 35 trials).

Diesel : Testing The reduced testing' frequency requested is acceptable provided staggered

- testing of the.four diesels.is scheduled within the 72 hour8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months time frame.

During a telecon on May 11, 1981 between Mr..T. A mk (NRR) and Mr. O. Kingsley

( APCO), we were advised of the following actions being taken:

1.

APC0 will modify plant procedures to assure operators are aware of the staggered. diesel test frequency and proper bus loading procedures with diesel IC out of commission.

2.

APC0 will arsure that each Senior Reactor Operator briefs each oncoming shif t and the Shift Technical Advisor.

3. ' APC0 currently has a Task Force. reviewing diesel failures.

Summary

,The licensoe h"as shown that for all-coobinations of loss of offsite power

,with and without a coincident LOCA at one of the units, there will always be power available to run at least one of the redundant safety trains Lat each unit. Staff analyses also showed that the inclusion of single failures of a-remaining diesel generator at either or both units would not change.this result.

The probability of core melt during the one-time 13 day Technical Specification

-change is acceptably low. Therefore, the proposed Technical Specification change is acceptable on a one-time only basis.

Environmental Consideration We have determined that the amendment does not authorize a cnange in effluent types or total amounts nor an increase in power level and will not result in any significant environmental impact.

Having made

.tnis determination, we have further concluded that the amendment involves an action which is insignificant from the standpoint of

~

environmental impact and, pursuant to 10 CFR 551.5(d)(4), that an environmental impact statement or negative declaration and environmental

' impact appraisal need not be prepared in connection with the issuance of this amendment, n

(1) because the amend.nent does not involve a significant increase in tne probabili ty or consequences of accicents previously consioered and coes not involve a significant decrease in e safety margin, the amend.aent does not involve a signiricant hazards consideration, (2) tnere is reasonable assurance that the nealth and safety of the public will not be endangered by operation in the proposeo manner, ano (3) re3ulations and the issuance or this uuenonent will not be iniuical to tne cor.raan defense ano sccurity or to tne healta ano safety of tne puulic.
