RESPONSE TO NRC IE BULLETIri tiO. 78-12,78-12A and 78-12B

Reference:

Reactor Pressure Vessel: Hope Creek II Gentlemen:

In compliance with subject bulletin, General Electric f4EBG requested Chicago Bridge and Iron liuclear Company (CBIN) tof conduct a records investi-gation of low alloy, high tensile weld deposits used in all reactor pressure vessels built in their, or their supplier's, facilities.

The purpose of this investigation was to identify any other atypical weld deposit similar to the one described in Bulletin 78-12.

In response to our request, CBIN has prepared a repcrt and submitted it to the NRC, as evidenced by the attached letter dated .May 1,1979. The report _ __

contains the attach.ed certification dated 4/30/79.

We have reviewed CBIN's report to the NRC and have not found any discrepan-cies. Consequently, we concuc with their certification and conclude that it is very unlikely that other, similar conditions (i.e., atypical weld deposits) exist in any reactor pressure vessel welds.

CBIli, in a separate communication to us, has stated that they do not have any archive material. Consequently, we are requesting that you review your inventory and advise the NRC accordingly1 Bulletin ~78-12,' Item 4)7 We recomend that you use this letter and the attached certification to satisfy the NRC request for verification of the generic search as outlined in IE Bulletin 78-12, Item 2.

Very truly yours /' RECElv e ,_,
