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, L. E. Kanter, P. R. Wohld and P. L. Eng of this of fice on
September 26 through November 17, 1986, 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. Plim1 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.
A written response
is required.
With regards to the July 23, 1983, loss of recirculation flow to the Unit 1
injection tank (BIT), we are concerned about operator awareness of the status
of current out of service (00S) jobs prior to issuing new 00S jobs.
More
generally, we are also concerned about operator awareness of the plant status,
i
We feel that operators should have available information regarding normal and
abnormal positions of valves, breakers, switches, and other operating control
components, and that this information should be considered prior to making
other necessary changes in the state of these components in order to prevent
causing a safety syste:r. or train from becoming inoperable.
Please include in
your response to this letter your plans to review and upgrade, if necessary,
operator awareness of plant status.
In addition, the ability of operators to
detect the loss of BIT recirculation flow was adversely affected by burned out
annunciator lamps.
Shift lamp checks had been reduced to a daily frequency
because the lamp checks have often resulted in blown fuses.
Please include in
your response to this letter the actions you plan to take to resolve the
overcurrent problem associated with annunciator lamp checks.
