Subject:
Braidwood Station Unit'1 Control Room Ventilation Interim Operation Plan NRC Docket No. 50-456
Reference:
(a) September 9, 1986 A.D. Miosi letter.to H.R. Denton (b) NUREG-1002, Safety Evaluation Report, Supplement
~#2, dated October, 1986
Dear Mr. Denton:
Reference (a) provide Commonwealth Edison's interim operation plan for the control room ventilation (VC) system.
Section 6.5.1 of reference (b) provided the staff evaluation and acceptance of that plan. This acceptance included the provision during fuel loading and reactor system testing before initial criticality that one train of the VC emergency make-up filter system be available including an associated chiller system and control room air handling unit.
The purpose of this letter is to provide, for your review and acceptance, our plan for a temporary chilled water source, via the service building chilled water system.
In an effort to complete the final modification and maintenance items on the control room chillers, prior to initial criticality, a temporary crosstie of the service building and-control room chilled water systems is being_ proposed. In effect this crosstie will add the load of the control room cooling to the service building chilled water system. This same_ method, utilized during early summer 1986 during the control room chilled water system preoperational testing, proved more than adequate in maintaining control room / auxiliary electric-room temperatures at design values.

{Lqs
Two temporary pipe sections, one supply and one return, will provide a flowpath from the service building chilled water header piping, (near the radiation chemistry laboratory air handling unit) to the control room cooling coils. All equipment in the control room chilled water system, other than the cooling coils and their associated supply and return water piping, will be isolated from the service building chilled water system. Utilizing the service building chillers, chilled water pumps and piping, an adequate source of 420F chilled water is thereby provided to cool all control room ve'.tilation loads. We anticipate this configuration to be in place for appropriately 14 days.
Please address any questions concerning this matter to this office.
Very truly yours, hv S. C. Hunsader Nuclear Licensing Administrator
