Mr. C. E. Larson
Director of Nuclear

Gentlemen:
This refers to the routine safety inspection conducted by Drs. S. Rozak
and M. J. Destmann of this office on June 21-24, 1982, of activities
at 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. Watz1 and others of your staff at the plant
on June 24, 1982, and with Mr. Schuelke by telephone on June 28-29, and
July 2, 1982, 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 bromine-82 was found on a charcoal adsorber at
activity levels comparable to iodine-131 levels both by your staff and
by the NRC inspectors using the Mobile Measurements Van.
Since your
staff has never found bromine-82 in previous charcoal adsorber samples
collected at your nuclear plants, it is our understanding that you will
investigate the source of this radionuclide and determine the mechanism
and amount of production and any safety significance of this radionuclide.
Please provide us a report of this investigation once your work is com-
pleted.
(0 pen Item 50-282/82-10-01; 50-306/82-10-01).
No. items of noncompliance with NRC requirements were identified during
the course of this inspection.
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
