Title:

Door Shock Absorber Test Plans and Results i

May 24, 1974 Report Date:

Westinghouse Electric Corporation-i Originating Organization:

Containment Systems. Branch, Office Reviewed by:

of Nuclear Reactor Regulation Sumary of Topical Report Westinghouse has designed a pneumatic lower inlet door shock absorber t

to replace the phenolic block shock absorber used in the design of the l

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

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

Report WCAP-8336 describes the new shock absorber design and the series of tests Westinghouse performed to demonstrate that the air box (pneumatic)

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