Docket No. 50-457
Commonwealth Edison Company
ATTN: Mr. Cordell Reed
Senior Vice President
Post Office Box 767
Chicago, IL 60690
Gentlemen:
This refers to the special safety inspection conducted by Messrs.
J. A. Hopkins, T. M. Tongue, and T. E. Taylor of this office from March 20
through April 5, 1990, at the Braidwood_ Station, Unit 2, authorized by NRC
Operating License No. NPF-77, and to the discussion of our findings with-
Mr. Querio and others of your staff at the conclusion of the inspection.
The special inspection was related to the inadvertent depressurization
of the reactor coolant system and rapid pressurizer cooldown event that.
occurred on March 18, 1990.
The enclosed copy of our inspection resort identifies areas examined during
the inspection. Within these areas, t1e inspection consisted of a- selective
examination of procedures and representative records, observations, and
interviews with personnel.
No violations of NRC requirements were identified during the course of this
inspection. The cause of the event appears to have originated as,a result
of poor communication practices between supervisors and operators. This
deficiency is being corrected by licensee initiated programs which will
identify non-routine evolutions that require increased communications
between supervisors and operators.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy. of
this letter and the enclosed inspection report will be placed in the NRC.
Public Document Room.
