SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos. 1&2; Docket Nos. 50-317 & 50-318 Resoonse to NRC Bulletin 88-05.

REFERENCE:

(a)

NRC Bulletin 88-05 and Supplements 1 and 2; Nonconforming Materials Supplied by Piping

Supplies, Inc. at Folsom, New Jersey and West Jersey Manufacturing Company at Williamstown, New Jersey Gentlemen:

As requested in Reference (a), we have reviewed our purchasing records to determine whether any West Jersey Manufacturing Company (WJM) or Piping Supplies, Inc. (PSI) flanges or fittings have been supplied to Calvert Cliffs for the period since January 1, 1976.

We have located 81 flanges furnished by WJMr 56 flanges are installed in the Auxiliary Feedwater (AFW) System and 25 flanges are in stock.

No PSI materials were found.

The flanges in the AFW system were field tested using the Equotip hardness method.

On July 8, 1988, the NRC Operations Center was notified within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> of receiving the test results that six flanges failed to meet the ASME Code specification for hardness.

An analysis to justify continued operation concluded that the flanges are capable of meeting their operational and design basis requirements.

Subsequently, NUMARC provided us with tables that correct Equotip readings at elevated temperatures.

The nonconforming flanges were rotested and only four flanges failed to meet the hardness specification (see Attachment 1).

NUMARC has compiled and analyzed utility and laboratory testing of WJM and PSI flanges and fittings.

These data

show, in general, that the suspect materials meet strength requirements and are satisfactory for ASME code applications.

NUMARC has also determined that the testing results justify a tolerance band 8809140221 800900 gDR ADOCK 0 % %7

i (i.e.,

116-137 HB) for the hardness acceptance criteria.

All of our WJM flanges meet this criteria and, therefore, the continued use of these flanges do not present a safety problem.

The in-stock flanges were sent to our metallurgical laboratory l

j for testing.

Four flanges failed the Code specification for hardness (HB <137) and three flanges failed the code specifica-j tion for ultimate tensile strength (UTS <70 ksi) (see Attachment 2).

We have segregated and retained all of the in-stock WJM i

i flanges.

In accordance with Supplement 1 to the Bulletin, we have enclosed j

all our test results for WJM flanges (see Attachment 3).

i Should you have any further questions regarding this matter, we i

will be pleased to discuss them with you.
