i ATTACHMENT 5 DIESEL GENEPATOR EXRAUST STACKS - TORNADO MISSILE e

BACKGROUND Per the request 01 the NRC Staf f, tbis additional information regarding the probabilistic analysis of the diesel generator exhaust stacks for tornado missiles is being provided.

Our analysis was based on infor-mation from the site-specific Seabrook tornado missile analysis, which was prepared by Applied Research Associates, Inc.

(Report C569, dated September 1983).

DISCUSSION In Section 3.5.2 of the Seabrook SER, NRC tornado missile acceptance criterion is given as:

"The probability of-significant damage to structure, systems, and components required to prevent a release of radioactitity in excess of 10CFR Part_100 following a missile strike, assuming loss of of f-site power, shall be less than or equal to a median value of 10-7 or a mean value of 10' 6 per year".

It is further stated that the numerical acceptance criteria,10-6 to 10-7 per year, satisfies the Standard Review Pir.n Guidelines for tornado missile fail-ure probability.

An analysis was performed by Seabrook to. evaluate the probability of tornado missiles impacting the diesel generator exhaust stacks. The analysis was based on the site-specific Seabrook tornado missile analysis which was reviewed and accepted by the NRC as discussed in Section 3.5.2 of the SER, Supplement No. 4.

Two of the tornado missile targets in the Seabrook specific analysis are on the roof of the diesel generator building.

One of the targets is actually the diesel generator exhaust stack openings which penetrate the roof of the diesel generator building.

The tornado missile impact prob-abilities on these targets were tchen adjusted by the ratio of the actual exhaust stack target area to the area of the tart.et modeled in the Sea-brook specific analysis.

~ t The concept of adjusting thel ornado missile. hit probabilities by ratios of target area was reviewed by the NRC censultant t

SER and was judged to be acceptable.

in Appendix J to the The major conclusion from our an.alysis of the diesel generator exhaus t is:

o The probability of a tornado missile impacting on a diesel generator exhaust stack is estimated to be about 10-6/ year.

The above estimate is a direct result of adjusting results from the site-specific study as previously noted.

The estimated tornado missile hit probability on the diesel generator stacks is considered to be con-servative for the same reasons as discussed in the site-specific study reviewed and approved in Appendix J to the SER.

i

- ~

ATTACHMENT 5 DIESEL GENERATOR EXHAUST STACKS - TORNADO MISSILE Furthermore, the tornado missile impact probability given above does not imply failure of the exhaust stacks in a manner that would preclude diesel generator operatiou.

The design of the exhaust stacks of fer additional shielding by the 60" diameter stack which surrounds the 40" diameter actual exhaust stack.

If the exhaust stack configuration is penetrated or severed by a tornado missile, the operation of the diesel generator would not be af fected. The probability that the exhaust stack configuration would be dented or deformed by a tornado missile such that the reduced flow area results in an increased back-pressure on the diesel generator engine exhaust system which would preclude operability is con-sidered to be lower than that given previously for impacting alone.

CONCLUSION Based on the above discussion, it is concluded that the diesel generator exhaust stack configurations comply with the NRC probabilistic tornado missile acceptance criterion.

STANDING OPERATING ORDER NO.86-013

SUBJECT:

DIESEL GENERATOR EXHAUST STACKS86-013 During the months of November through March each Diesel Generator exhaust stack shall be checked periodically af ter any significant snow fall for snow drifting over the stack rendering the Diesel inoperable. Attached is a copy of the memo explaining the necessity of these checks.

The static red drop test will not be perforned at Seatrook.

j Performance of this teot at other facilities has ree,ulted in abnormally high power ti?.ts and large Xation oscilla.iona and taay inercase the risk,of fuel fa*tlure. Performance of this test ac i

plants similar to Seabrook has providad ample data to demonstrata that Westinghouse caraputer codes are aSle to.idequately predict core thermal and nuclear parameters for RCCA misalignrients up to and including full insertion of a single high w'rth rod.

15. The psuedo-rod ejection test will not be performed at ; greater than 10% power at Seabrook. Performance of this test may result in violation of the Taconical Specificatics Limits on peaking facter.

Since the accident analysis for Saa'arook shows the acpwet ejected 1

rod worth and power peaking fact ar are bounded by the zero pcwer case, the caleu18ti.or;al model will be verified during t;he pseudo-i rod-ejection test at zero pWer.

INTEGRATED PLANT C00LDOWN FROM HOT FUNCTIONAL TESTS

.Obisetive To demonstrate the ability to bring the plant from normal operating tamperature and pressure to cold shutdown conditions.

Pirnt Conditions / Prerequisites Tha plant is at normal temperature and pressure following the completion of hat. functional testing.

Tast Method Th2 plant will be brought to.eett shutdown co itions using steam dumps and tha residual heat removal system, m.

. m i. d.s During operation of the rscidual heat. removal system, cooldown rates will be monitored and controlled, cnd data will be collected to verify its heat removal capability. The cool-down limitationa of Technical Specification 3.4.10.1 will not be exceeded.

At specific points, the cooldown will be terminated to allow the performance of specified hot functional tests.

48 Acceptance Criteria

.s The plant has been brought to cold shutdown conditions in accordance with normal plant operating procedures.
