SUBJECT:
EXEMPTION FROM THE REQUIREMENTS OF 10 CFR 70.24 - PRAIRIE ISLAND NUCLEAR GENERATING PLANT. UNITS 1 AND 2
Dear Mr. Anderson:
It is our understanding that Prairie Island Nuclear Generating Plant. Units 1 and 2. does not meet the requirements of 10 CFR 70.24 and does not have an exemption from this rule.
You may apply for an exemption under the provisions of 10 CFP 70.14.
Your exemption application should verify that Prairie Island Nuclear Generating Plant. Units 1 and 2. meets the following criteria:
1.
Plant procedures do not permit more than one pressurized-water reactor fuel assembly to be in transit between their associated shipping cask and dry storage rack at one time.
2.
The k-effective of the fresh fuel storage racks filled with fuel of the maximum permissible U-235 enrichment and flooded with pure water does not exceed 0.95, at a 95% probability. 95% confidence level.
3.
If optimum moderation of fuel in the fresh fuel storage racks occurs when the fresh fuel storage racks are not flooded, the k-effective corresponding to this optimum moderation does not exceed 0.98, at a 95%
probability. 95% confidence level.
4.
The k-effective of s)ent fuel storage racks filled with fuel of the maximum permissible J-235 enrichment and filled with pure water does not
/
exceed 0.95. at a 95% probability. 95% confidence level.
5.
The quantity of forms of special nuclear material, other than nuclear fuel, that are stored on site in any given area is less than the
{)h, quantity necessary for a critical mass.
6.
Radiation monitors, as required by General Design Criterion 63, are provided in fuel storage and handling areas to detect excessive radiation levels and to initiate appropriate safety actions.
7.
The maximum nominal U-235 enrichment is 5 weight percent.
