Robert A. Clark Large Capacity Iquipment Snubbers:
The equipment snu ber is of the traditional design.
However, the poppet value is so designed to of fer a performance insensitive to the contact position wnicn is a desirable feature from the standpoint of reliability.
,an in-service, in-p,iece testir.g momu,.e ca,i,.ec :estan is cresently s ing s
e finali:ed for metile use witnin re;ui ed service areas for nuclear power facili;ies.
This rcdule.-;ill have tne cacabilit;, of testing snutter performanca parameters without tne remeval and reinstallaticn of the snuober ceing tested.
It will not only reduce tne time ar.d ef fort recuired for testing, but will also avoid possible snubber damage resulting from the re oval and reinstallation af a snubber being testec.
(Tne Testan general 3rrangement and test equipment hcck-up diagrams are attached.)
