Docket No. 50-151
University of Illinois
ATTN: Dr. B. G. Jones
Acting Chairperson
Nuclear Engineering Program
214 Nuclear Engineering Laboratory
103 S. Goodwin Avenue
5
Urbana, IL 61801
Gentlemen:
This refers to the special inspection conducted by Mr. T. N. Tambling of this
office on October 8,1986, of activities at the University of Illinois Nuclear
Reactor Laboratory authorized by NRC Operating License No. R-115 and to the
discussion of our findings with you and others of your staff at the conclusion
of the inspection and during the Enforcement Conference held in the NRC
Region III office on October 28, 1986.
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
with NRC requirements, as specified in the enclosed Notice of Violation. The
root cause of this violation is your apparent failure to recognize that
continued operation of the reactor with a wiring error that could circumvent
the Standard Control Rod Position interlock violated your license and NRC
regulations.
In this case, continued reactor operations with the known wiring
error constituted a change to the description of the interlock in your Safety
Analysis Report and license and therefore required prior NRC approval. Such a
violation could be classified as Severity Level III.
However, because of the
low safety significance associated with the wiring error and the fact that
the interlock would have performed its intended function in all normal
operations, the violation has been classified as Severity Level IV.
In your
written response to this violation, you should address those actions taken or
planned to preclude this failure to recognize the operability requirements of
your license and need to request formal NRC approval prior to deviating from
these requirements.
In accordance with the Commission's regulations, a copy of this letter and
the enclosed inspection report will be placed in the NRC's Public Document
Room.
The responses directed by this letter (and the accompanying Notice) are not
subject to the clearance procedures of the Office of Management and Budget
as required by the Paperwork Reduction Act of 1980, PL 96-511.
