4 1. PURPOSli l.1 Objective This procedure satisfies Technical Specification Surveillance 4.8.4.1.a.2 for overcurrent testing of the following containment penetration overcurrent protection devices:

Load center breakers l

Gould Ampcap MCC starters j

  • Molded case breakers 1.2 Discussion Surveillance requirement 4.8.4.1.a.2 requires that 10% of each type of penetration conductor overcurrent protective devices below 4KV be functionally tested every 18 months. The function of the penetration conductor overcurrent protective device is to open the circuit on an overcurrent condition. Operability is proven by injecting overcurrent levels into the protective device and ensuring it trips within its required time band.

Satisfactory completion of section 4.1, meets the requirement for load center breakers.

Satisfactory completion of section 4.2, meets the requirement for Gould Ampeap MCC Starter.

Satisfactory completion of section 4.3, meets the requirement for molded case breakers.

For each circuit breaker found inoperable during these functional tests, an additional 10% of all the circuit breakers of the inoperable type shall also be tested until no more failurcs are found or all circuit breakers of that type have been tested.[+ LER 97-004-00]

This procedure should be performed prior to performing Urcaker PMs (SP 3712TA and SP 3712TB). Performing the PM first would precondition the breaker.

Instructions on operating the test equipment may be found in its operating instruction manual or in the MP 3787 series procedures. This procedure overrides any conflicts found between it and the operating instruction manual or the MP 3787 series procedure.

  • 1.3 - Applicability gi "

This procedure applies to all circuit breakers described in Tecn:. cal Specifications, Millstone Nuclear Power Station, Unit No. 3, OPS Form 3273 - 3/4.3.8.4.1," Containment Penetration Conductor Overcurrent Protective Devices." This surveillance applies in modes 1,2, 3, and 4, 1.4 Frequency A minimum of 10% of each type of breaker below 4KV shall be functionally tested at least once every 18 months. Circuit breakers selected for functional testing shall be selected on a rotating basis.

SUMMARY

OF CIIANGES

- 7.1 - Reworded, rearranged and regrouped steps from previous revision.

7.2 Removed Long and Short pick-up tests.These tests were not required to be performed by tech specs.

7.3 LER 97-004-00 corrective actions required that SP3712T be rewritten to ensure procedure was in verbatim compliance with technical

specifications. The following changes were'made in rev 6

l 1 i

'~

!- 7.3.1 Add requirement to do additional testing to a molded case i breaker or unitized starter if t fails a single pole test. (ACR ,

M3-97-0136) 7.3.2 Added steps to schedule surveillance for an additional 10%

1 sample of breaker of the same type for cach circuit breaker found I

inoperable, 7.4 60 month surveillance requiren ents have been moved to SP 3712TA and SP 3712TB.

7.5 Changed procedure order to take as found data prior to performing preventative maintenance in accordance with NRC Information Notice 96-24," Preconditioning of Molded-Case Circuit Breakers Before Surveillance Testing."

7.6 Containment penetration breakers 3SCA-PNL5N (CKT2) and 3RCP-PNL3A ( -R4B) were listed in Maint. Form 3712T-I twice.

Removed duplicate in this revision, each breaker is only required to be tested once cach 18 months.
