Northern States Power Company
ATTN: Mr. L. R. Eliason
Vice President, Nucicar
Generation
414 Nicollet Mall
Minneapolis, MN 55401
Gentlemen:
This refers to the routine safety inspection conducted by Messrs.
P. L. Hartmann, Esquire, and D. C. Kosloff of this office on August 14
through September 24, 1990, of activities at the Prairie Island Nuclear
Generating Plant Units 1 and 2, authorized by NRC Operating Licenses No.
DPR-42 and No. DPR-60, and to the discussion of our findings with
Mr. E. L. Watz1 and other members of your staff 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.
Three licensee identified (self disclosing) non-cited violations are identified
within this report. These issues involved a failure to follow procedure
resulting in an auxiliary feed pump autostart; improper review of an installation
procedure resulting in the autostart of both auxiliary feed pumps during hardware
installation of an ATWS mitigation system; and performance of an electrical
maintenance procedure which did not account for de energization of chlorine
monitors. The latter issue resulted in the autostart of the 122 Control Room
Special Ventilation System. We have chosen not to issue a notice of violation
because these violations meet the criteria delineated in 10 CFR Part 2.
Also,
we recognize that with the large number of Unit 2 outage activities, the
opportunity for these type of errors is increased.
However, the NRC has
previously discussed attention to detail concerns with Northern States Power
and our expectations with respect to those concerns remain unchanged and will
be discussed in an upcoming NRC management meeting.
In accordance with 10 CFR 2.790(a) of the Commission's regulations, a copy of
this letter and the enclosure will be placed in the NRC Public Docue.ent
Room.
