CP-86-04 (INTERIM REPORT) 1 l
Gentlemen:
On February 13, 1987, we notified you by our letter logged TXX-6260, of a l
deficiency involving the placement of Richmond inserts in the proximity of loaded embedded plates which could compromise the integrity of adjacent shear cones.
This is an interim report of a deficiency which is reportable under the provisions of 10CFR50.55(e).
Our last interim report was logged TXX-6423, i
dated May 1, 1987.
Our corrective actions previously specified are continuing as planned.
Since our last report, spacing criteria issues arising from the internal review of Design Specification 2323-SS-30 (Structural Embedments) have been resolved and l
quality control instructions have been added as an appendix to the specification. This effort has delayed the issuance of the specification revision which is expected to be issued shortly.
Following the issuance of this specification, engineering will complete their evaluation to identify all corrective actions and means to prevent recurrence for this and related l
issues, as described in our letter logged TXX-6260, dated February 13, 1987.
We anticipate submitting our next report no later than October 5,1987.
Very truly yours,
/
