Docket No. 50-295
Docket No. 50-304
Commonwealth Edison Company
ATTN: Mr. Cordell Reed
Vice President
Post Office Box 767
Chicago, IL 60690
Gentlemen:
This refers to the routine safety inspection conducted by NRC inspectors,
M. M. Holzmer and P. L. Eng of this office on December 30, 1986 through
February 3,1987, of activities at the Zion Nuclear Generating Station,
authorized by Licenses No. DPR-39 and No. DPR-48 and to the discussion
of our findings with Mr. G. Pliml at the conclusion of the inspection.
The enclosed copy of our inspection report identifies areas examined during
the inspection. Within these areas, the inspection consisted of a selective
examination of procedures and representative records, observations, and
interviews with personnel.
During this inspection, certain of your activities appeared to be in violation
of NRC requirements, as specified in the enclosed Notice. Our concern with
this violation is not based so much on the short time that surveillance
requirements were not implemented, as on the six months that were available
to put procedures in place before the requirements took effect. A written
response is required.
With regard to the December 30, 1986 event in which Unit 2 Reactor Coolant
System pressure was below the Technical Specifications lower limit of 2205
psig, we are concerned that this pressure transient was not detected for over
three hours by either the unit operator or shift supervision. We are also
concerned that no Reactor Coolant System low pressure alarm was received.
In addition to your response to the Notice of Violation described in the
preceding paragraph, please include your assessment of the two concerns
described above, and any actions taken or planned to prevent their recurrence.
In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of
this letter, the enclosures, and your response to this letter will be placed
in the NRC Public Document Room.
