) OL Contention re DS-k16 circuit breakers for safe reactor shutdown at Harris (based on new info )

Wells Eddlenan hereby files the contention (#161) below, which could not have been filed previously because its basis was not known to me before 5-7-83 and not available before E-20-83:

Contention 161: Applicants have not demonstrated that the Enrris nuclear reactors can be safely shut down when shutdown is r~cuired, e i

because of defects and possible nalfunction of' West?nghouse DS-h16 circuit breakers used in the safety-related shutdown systens at Harris, BASIS:

ff4-5 (InsideNRc5-2-83): Westinghouse has reported to NRC on h-20-63 that it has found defects whfch can cause the DS-h16 1

i circuit breakers to nalfunction which "could create conditions under

! which the RT3xs (reactor trip breakers ) night not open autonatically

(, 030-boo on demand fron the reactor protection sy sten."

I oo This failure could mS cause an ATWS event like that which occurred at Salen, especially m

g given the use of the sane type breaker in Harris' redundant shutdown OC

$@ systens.

ATWS events .at or near full power pose a very great danger

! Sct

'g to the health and safety of the oublic. Therefore, Apli cants nust dencastrate that the DS-h16 breakers at Harris will not fail and g cause a failure to shut down a Harris reactor when that's necessary.
