SUBJECT:
HADDAM NECK - NEW SWITCHGEAR ROOM - REQUEST FOR ADDITIONAL INFORMATION (TAC #65034)
On February 28, 1989, the staff with Connecticut Yankee Atomic Power Company (CYAPCO) to discuss the new switchgear room at the Haddam Neck site. At this time your staff provided several Plant Design Change Records (PDCRs) to c
describe the changes and additions being made as a result of the new l
switchgear room. Based on our review of your PDCRs, the NRC has determined that additional information is needed to complete our review.
Please respond-within 60 days of the receipt of this letter.
We believe this response time is necessary to support your start-up from CYCLE 16.
The reporting and/or recordkeeping requirements contained in this letter affect fewer than 10 respondents; therefore, OMB clearance is not rec;uired under P.L.96-511.
Sincerely,
/s/

ENCLOSURE:
REQUEST FOR ADDITIONAL INFORMATION HADDAM NECK PLANT NEW SWITCHGEAR PROJECT 1.
PDCR No. 910, Rev. O page 22 states that BA-MOV-373 control circuitry has been modified to incorporate contacts from the ARTP.
No similar statement is made for valves SI-MOV-901, SI-MOV-903 and SI-MOV-854A.
Will the control circuitry for these valves also be isolated from the main control room by the ARTP? Do the remaining loads supplied from MCC 12-11 have any indication or contro', features other than the molded case circuit breakers?
2.
PDCR No. 902 gives no details regarding the remote instrumentation panel.
Is the discussion presented on page TR-17 and Sketch IV-2 of your December 8, 1987 Progress Report No. 7 still applicable?
If not, please indicate any significant changes that have occurred since then.
3.
Describe how the power supply for speed control of the charging metering pump P-11-1A, and for the control of valve CH-A0V-278 from the new switchgear room is protected against a fire in the control room.
Are separate breakers / fuses used from the 120/208 distribution panel to the control room and to the new switchgear room?
w 4.
Provide the load profiles for Batteries 1A and IB for the worst case loading condition and confirm that the batteries are adequately sized in accordance with IEEE Standard 485.
5.
Describe how the non-Class 1E instrumentation at the remote instrument panel in the new switchgear room is electrically isolated from the Class IE Vital-ac power supply. Describe the separation between trains C and D of the instrumentation circuitry.
