Title:

Door Shock Absorber Test Plans and Results , ,

i May 24, 1974 Report Date:

i Westinghouse Electric Corporation-

• Originating Organization: , ,

Containment Systems. Branch, Office -

t i.

Westinghouse has designed a pneumatic lower inlet door shock absorber l to replace the phenolic block shock absorber used in the design of the

~ ice condenser system approved in the letter. from D. B. Vassallo to C. ,

i Eiche1dinger, dated April 29, 1975. The pneumatic design was selected l

because of simplified fabricating procedures, and inspection and i maintenance during plant operation.

Report WCAP-8336 describes the new shock absorber design and the series ~

j of tests Westinghouse performed to demonstrate that the air box (pneumatic) lower inlet door shock absorber can reolace the phenolic block shock '

absorber. The test program utilized three prototype and two production j

• The tests were identical to the tests performed ,

air box shock absorbers. ,

I to demonstrate the adeouacy of the phenolic block shock absorber design.  ;

The phenolic block shock absorber tests are described in HCAP-8110, i- Supplements 1, 3 and 4.

Sumary of Evaluation

i A sumary of our evaluation 'of the tests to demonstrate the adenuacy of  :

l l the phenolic block shock absorber design was presented in ,

l April 29,1975,the air box lower inlet door shock absorber were the same as tho We find that these tests are adeauate the phenolic block shock absorber.to demonstrate the acceptability of '

Sumary of Staff Position .

We conclude that WCAP-8336 presents an acceptable design and testing program. for the air box lower inlet door shock absorber.

We find WCAP-8110, Supplement 5 an acceptable non-proprietary version of WCAP-8335.
