I L-97-325, Attachment 3, DESIGN FEATURES VOLUME 5.4.2 The total water and steam volume of the reactor coolant system is 10,931 + 275 cubic feet at a nominal T of 572'F.

5.5 METEOROLOGICAL TOWER LOCATION

5. 5;1 The meteorological tower shall be located as shown on Figure 5.1-1.

5.6 FUEL STORAGE CRITICALITY

.6.1 The spent fuel storage racks are designed and shall be mai ined with:

ess than or equal to 0 when f1 ooded

~pe& wi f equi val ent to funborated'ater, 1 which includes a co ervative al lowance of 0. 4 hk ff for eff Total Uncertainty.

2. A nominal 8. inch center-to-c er distance between fuel

~e ~~ assemblies pla in the sto ge racks.

s<<~ i'J 3. A boron concentra i eater than or equal to 1720 ppm.

Region I can be used store fu which has a U-235 enrichment less than or equa o 4.5 weight pe ent'. Region II can be used to store fuel ch has achieved suffi ent burnup such that storage in gion I is not required. The nitial enrichment vs.

burnup r uirements of Figure 5.6-1 shall be et prior to storage of f assemblies in Region II.

b. he new fuel storage racks are designed for dry stora of unirradiated fuel assemblies having a U-235 enrichment 1 than or equal to 4.5 weight percent, while maintaining a k << o ess than or equal to 0.98 under the most reactive conditi5h.

DRAINAGE 5.6.2 The spent fuel storage pool is 'designed and shall be maintained to prevent inadvertent draining of the pool below elevation 56 feet.

CAPACITY 5.6.3 The spent fuel storage pool is de ned and shall be maintained with a storage capacity limited to no more than fuel assemblies.

5.7 COMPONENT CYCLIC OR TRANSIENT LIMITS f,560 5.7.1 The components identified in Table 5.7-1 are designed and shall be maintained within the cyclic or transient limits of Table 5.7-1.

~~~y'A Proposed License Amendment I hI H.

INSERT A to L-97-325, Attachment 3 5.6.1 a. The spent fuel pool and spent fuel storage racks shall be maintained with:

A k,<< equivalent to less than 1.0 when flooded with unborated water, including a conservative allowance for biases and uncertainties.

2. A k,<< equivalent to less than or equal to 0.95 when flooded with water containing 520 ppm boron, including a conservative allowance for biases and uncertainties.

3. A boron concentration greater than or equal to 1720 ppm.

A nominal 8.96 inch center-to-center distance between fuel assemblies placed in the storage racks.

5.6.1 b. Fuel placed in Region I of the spent fuel storage racks shall be stored in a configuration that will assure compliance with 5.6.1 a.1 and 5.6.1 a.2, above, with the following considerations:

Fresh fuel shall have a nominal average U-235 enrichment of less than or equal to 4.5 weight percent.

2. The reactivity effect of CEAs placed in fuel assemblies may be considered.

3. The reactivity equivalencing effects of burnable absorbers may be considered.

The reactivity effects of fuel assembly burnup and decay time may be considered as specified in Figures 5.6-1c through 5.6-le ~

5.6.1 c. Fuel placed in Region ZI of the spent fuel storage racks shall be placed in a configuration that will assure compliance with 5.6.1 a.l and 5.6.1 a.2, above, with the following considerations:

Fuel placed in Region EI shall meet the burnup and decay time requirements specified in Figure 5.6-1a oz 5.6-1b.

2~ The reactivity effect of CEAs placed in fuel assemblies may be considered.

3. The reactivity equivalencing effects of burnable absorbers may be considered.

5.6.1 d. The new fuel storage racks are designed for dry storage of unirradiated fuel assemblies having a U-235 enrichment less than or equal to 4 ' weight percent, while maintaining a k,<< of less than or equal to 0.98'nder the most restrictive condition.
