95 of these CBs were purchased from Spectrum Technologies and the remaining 50 were purchased from Eaton-Cutler Hammer.
b.
We have verified the traceability of these molded-case CBs to the CBM.
95 CBs purchased from Spectrum Technologies i
have been verified traceable from the Westinghouse Spartanburg Distribution Center No. W34 in Duncan, South Carolina to WESCO in-Albany, NY then to Spectrum and subsequently to Peach Bottom.
The 50 CBu purchased from Eaton-Cutler Hammer have been verii'ed traceable to the CBM by Eaton-Cutler Hammer Quality Assurance.
Items No. le through 5 of the Actions Requested are not applicable as the CBs identified as stored spares are traceable to the CBM.
In accordance with item No. 6 of the Action Requested, we shall maintain the-information obtained during this investigation for at least a period of 5 years.
In accordance with item No. 7 of the Action Requested, future purchases of molded case circuit breakers intended for safety related use at PBAPS will be ordered from the equipment manufacturer with the requirements of 10 CFR 50, Appendix B, and 10 CFR 21 invoked.
If the purchase order is to be fulfilled by
-Document Control Desk April 3, 1989 Page 3 a supplier other than the manufacturer, the order will require that additional documentation traceable to the manufacturer in addition to the 10 CFR 50, Appendix B, and 10 CFR 21 requirements must be provided.

For CBs that pass these tests, the only information required is the number, manufacturer, model number, and to the extent possible the procurement chain of CBs tested (summaryareport format is acceptable).
For CBs that fail i
these test (s), these reports should indicate the test (s) and the values of test parameter (a) at which the failure (s) occurred, as well as the corresponding manufacturer, model number, and to the extent possible, the procurement chain.
RESPONSE
Not Applicable.
The CBs being maintained as stored spares have been tr aced to the CBM, therefore, no testing has been performed at PBAPS Units 2 and 3.
