DESIGN FEATURES 5.4 REACTOR COOLANT SYSTEM DESIGN PRESSURE AND TEMPERATURE 5.4.1 The reactor coolant system is designed and shall be maintained:

a.

In accordance with the code requirements specified in Section 4.1.2 of' the -

FSAR, with. allowance for normal degradation pursuant to applicable Surveillance Requirements, b.

For a pressure of 2500 psig, and c.

For a tempe sture of 6500F, except for the pressurizer and pressurizer surge

-line, which is 6700F.

VOLUME 5.4.2 The total water and steam volume of the reactor coolant system is 12,180 1 200 cubic feet at a nominal Tavg of 5250F.

5.5 METEOROLOGICAL TOWER LOCATION 5.5.1 The ineteorological tower shall be located as shown on Figure 5.1-1.

5.6 FUEL STORAGE CRITICALITY 5.6.1, The new fuel storage racks and spent fuel storage racks in pool "B" are designed l

and shall be maintained with a nominal 21-1/8 inch center-to-center distance between fuel assemblies placed in the storage racks. The high density spent fuel storage racks in pool "A" are designed and shall be maintained with a nominal 10.5 l

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

All of these rack designs ensure a keff equivalent tos0.95 with the storage pool filled with unborated water. The keff ofs0.95 includes a conservative allowance of >1% ak/k for uncertainties. In addition, fuel in the new and spent fuel storage racks shall have a U-235 loading of $ 6.14 grams of U-235 per axial centimeter of 4
