DEFICIENCY EVALUATION 50.55 (e) , 's ,;,

I. DESCRIPTION OF DEFICIENCY

During a Bechtel repair operation to the Reae or Coolant Pump No. lA suppliedby Combustion Engineering, imperfections (sand holes) were found'$n thrust

-bearing housing 8000-400-001. Repair attempt by grinding to remove sand holesdisclosed-imperfections extended below .750" depth.

II. ANALYSIS OF SAFETY IMPLICATIONS ,

As per the attached Combustion Engineering letter V CE-15596 dated 12-4-81,this conditon is evaluated as not reportable since no foreign material remainedin the " cavity" and the defect does not affect the . structural' integrity of thethrust bearing housing. Should this condition have remained undetected itwould not represent a safety significant condition.

~I

II. CORRECTIVE ACTION )~

,/ , \\' j N-- ,

..

The Bechtel repair will be completed as per the referenced Combustion s( ,

' C- 'Engineering letter and documented by NCR NC-563.': .

(DearMr. Bingham: N

CE-KSB Engineering and Quality Assurance have reviewed DER #81-42 and have ,

the following comments:

The conditions described in NCR-NC-520 and idt hC-563 were addres' sed ''

and documented (Attachment (1) by CE-KSB and' Glacier Metal Company LTD(Bearing Housing manufacturer) in November,1979, and again in August,198T. These conditions were found not to be detrimental to performanceof the uni.t6 CEsKSB's acceptance of the subject condition is based on(1) the def,4ct does not affect structural integrity, and (2) followinga high pressurer flush of the area any possible imefgn material remain-ing in the Ocavity" will not become dislodged since' there is noappreciable oil velocity in the area during operation.

The disposition by C-E to grind .750" maximum depth was based uponincomplete information since Scot-Test LTD's UT Report (Attachment.(1))shows porosity at depths greater than .750". CE-KSB has again reviewed

|this condition, and finds the component acceptable for use. However,rework must be perfonned as the cavity has been excavated. Rework'

should consist of " cosmetic" grinding to remove rough and feathered edgeswith blending into surrounding area, high pressure flush to remove for,eign t

|material. The final prepared area shall be sealed with Synobel- e,- ,

\Isolphthalete manufactured by Imperial Chemical Company, Specification, s'

Number F270-4007 which will be supplied by CE-KSB. ,
