M97997 and M97998 'c uest for Additional Information L-97-171 ATTACHMENT Page 1of 2 To accelcratc the processing ofFPL's application for an exemption from 10 CFR 70.24, CriticalityAccident Requirements, for areas designated forncw (unirradiatcd) fuel handling and storage, Reference (2) rcqucsted FPL to verifythat St. Lucie Units 1 and 2 meet seven criteria for granting exemptions from this rule.
Criterion I: Plant procedures do not permit more than I PH%fuel assembly to be in storage or in transit between its associated shipping cask and dry storage rack at one time.
R~es onse l: FPL verified that St. Lucic plant procedures do not permit more than one PWR fuel assembly to be in storage or transit between its associated shipping cask and diy storage rack at one time.
Criterion 2: The keffective ofthefresh fuel storage racks filledwithfuel ofthe maximum permissible U235 enrichment andflooded with pure water does not exceed 0.95, at a 95% probability, 95% confidence level.
~Res onse 2; FPL verified that the I;-effective values ofthe fresh fuel (dry) storage racks filledwith fuel ofthc maximum permissible U-235 enrichment (4.5 weight-percent) and flooded with unborated water do not exceed 0.95 at a 95% probability, 95% confidence level for St. Lucie Units 1 and 2.
Criterion 3: Ifoptimum moderation offuel in the fresh fuel storage racks occurs when the fresh fuel storage racks are notflooded, the k-effective corresponding to this optimum moderation does not exceed 0.98, at a 95% probability, 95% confidence level.
R~es onse 3; FPL verified that the kwtfcclivecorresponding to the most reactive condition in thc St. Lucia Unit 1 and Unit2 fresh fuel (diy) storage racks with4.5 weight-percent enriched fuel assemblies docs not cxcecd 0.98 at a 95% probability, 95% confidence level.
Since the most reactive condition is equivalent to the optimum moderation condition, the diy fuel storage racks meet this criterion.
Criterion 4: The k-effective ofspent fuel storage racks filledwithfuel ofthe maximum permissible U-235 enrichment andflooded withpure water does not exceed 0.95, at a 95% probability, 95% confidence level.
~Res onse 4 FFL vcrificdthat thc k effective ofSt. Lucia Unit I cnd Unit 2 spent fuel storage racks filledwith fuel ofthe maximum permissible U-235 enrichment (4.5 weight-percent) and flooded with unboratcd water does not excccd 0.95 at a 95% probability, 95% confidence level.
Criterion 5: The quantity offorms ofspecial nuclear material, other than nuclear jiiel, that are stored on site in any given area is less than the quantity necessary for a critical mass.
R~es onse 5:
Forms of Special Nuclear Material (SNM), other than nuclear fuel, arc not stored in the dry fuel storage areas of either St. Lucic Unit 1 or Unit 2. FPL verified St. Lucic plant compliance with regulations governing SNM accountability and control, and determined that the quantity offorms ofSNM, other than nuclear fuel, that are stored on site in any given area is less than the quantity necessary for a critical mass.

Criterion 7: The maximum nominal U-235 enrichment is 5%.
~Res onse 7:
FPL verified that thc mnaimum nominal U-235 enriciunent for St. Lucia Units i and 2 is 4,5%
