i i
j 1.
DESCRIPTION OF DEFICIENCY Bergen Paterson, a sub-supplier to Applied Engineering Co. (APCO), used magnetic test methods fo r non-des truct ive examinations that were in conflict with those speci fied.
The welded clevises examined for weld acceptability and initially accepted by Bergen Paterson are not ac cep t-able for BVPS-2 application.
2.
AFFECTED COMPONENTS 1
The af fected components are clevises used on pipe rupture res traint s.
t 3.
PRELIMINARY SAFETY EVALUATION If the pipe rupture res traint s should fail after a pipe bresk, other safety related eq uipment within the vicinity of the ru ptur e could be damaged.
An engineering evaluation of the weld de ficiencies is c ont inuing.
4.
IMMEDIATE ACTION TAKEN, APCO issued a stop-work order to Bergen Paterson on May 5,1983.
The stop-work order has now been lif ted based on an acceptable program for the remanu facture of the c levises.
In order to assure conformance to specification, APCO has assigned a resident inspector to Bergen Pater-son, and DLC is pe rfo rming increased surveil lance at the vendo r 's d
- plant, k
5.
ADDITIONAL REPORTS The results of the evaluation are expected to be available by mid-July.
l An additional report on this issue will be submitted by July 20, 1983.
