Subject:
Environmental Qualification of Electrical Equipment
Dear Sir:
Enclosed is our revised equipment list for electrical equipment qualification purposes which we agreed to submit at our mid-July 1980 site audit with the NRC staff. This list has been revised to include only electrical equipment and displays involved in direct mitigation of a LOCA, MSLB, and FWLB.
The following changes have been made:
1.
Equipment required for cold shutdown has been added as per your guidelines.
2.
Enclosure B (asterisked items on Enclosure A) identifies equipment located in harsh environments (both inside and outside containment). Equipment in harsh environments resultird from recirculating fluid lines have not been identified. This information is still being developed and will be submitted in several weeks. Equipment not in a harsh environment (i.e., control room, switchgear room, and some locations in the PAB) remain on the list (Enclosure A) as per the guidelines.
3 Pneumatic equipment has been deleted for the purposes of this list.
4.
Equipment installed as a result of NUREG-0578 short term requirements has been added.
We are still in the process of updating our equipment data sheets for equipment in harsh environments and will submit these in several weeks.

~ August 1, 1980 Attention:
Mr. Dennis M. Crutchfield,' Chief
~Page 2 These data sheets are being revised to provide additional information on the specific environment, to add radiation doses, and to supply vendor information.
The following additional information is also submitted and was requested at the site meeting. The maximum containment water level, after a LOCA, was calculated to be approximately elevation 1057' (refer to FM-lC and FM-lX attached). This calculation assumed an injection of approximately 18,580 ft3 of water into the containment and a concrete displacement of approximately 14000 ft3 The details of the calculation are summarized in Enclosure C.
We trust this information is satisfactory; however, if you have any questions,
. please contact us.
Very truly yours, YANKEE ATOMIC ELECTRIC COMPANY
