SEP 071988 Docket No.
50-456 License No. NPF-72 EA 88-91 Comonwealth Edison Company ATTN: Mr. James T. O' Conner President 4
Post Office Box 767 Chicago, Illinois, 60690-0767 Gentlemen:
By a letter dated June 20, 1988 Comnonwealth Edison responded to a Notice of l
Violation (tiOV) and Proposed Im>osition of Civil Penalty which was issued by the NRC staff May 6, 1988 for tiree violations associated with design control deficiencies for the Control Roon Ventilation System at Braidwood tlnit 1.
In that letter Cormonwealth Edison, in part, took exception to Violation 8 stating that the preoperational testing performed on March 4 and 11, 1967 could not have detected the logic switch wit ing problem because the irplementing design change 4
was not completed until a nunhr of weeks af ter that testing.
The tiFC staff agrees that the testing on the dates stated would not have detected the problem, i
however, by Comonwealth Edison's admission, the testing that was performed subsequent to the completion of the design change was not adequate to detect I
the problem.
In addition, you agreed that the Control Room Ventilation System was degraded as stated in the cover letter to the itay Notice of Violation.
l Acordingly, the staff is inodifying Violation B as follows:
l
'l Contrary to the above, the licensee's test program did not demonstrate that the Control Room Yentilation Systems (CRYS) weuld perforn satisfactorily in that CRVS preoperational testing, which was corpleted l
)
before the CRVS were declared operable at the time of Unit 1 initial criticality on May 29, 1987, did not identify that heater interlock logic i
switches were wired incorrectly, that specified switch setpoints had not j
been adjusted, and that CRYS were in degraded condition.
l The fiRC staff intends to consider Violation B as medified above when reviewing j
Commonwealth Edison's response to the NOV and Proposed Irposition cf Civil 3
renalty.
Sheuld you have any further coments on this specific issue, please i
submit ' hen in writing to the Directer, Office of Enforcer:ent U.S. Nuclear Regulat Jry Comission, with a copy to the Regional Moinistrator within twn weeks t
of the date of this letter.
