EMERGENCY CORE COOLING SYSTEMS SURVEILLANCE REQUIREMENTS __(continued) 4.
Verifying that the following valves are in their normally closed position with power to the valve operator removed by disconnecting the power cables as they leave the motor starter:
Valve Number Valve Function
- a. CS-MOV-532 LPSI Recirculation Line
- b. CS-MOV-534 LPSI Pump Header Isolation Valve Bypass Note: CS-MOV-532 may be opened for < 30 minutes once per week for safety injection tank mixing or low pressure safety injection pump testing after restoring power to the valve operator. Insure that power to the valve operator is properly removed after closing the valve.

DESIGN FEATURES CONTROL ROD 5.3.2 The reactor core shall cont'in 24 cone rol rods. Thecontrolrodsshail a
contain a nominal 90 inches of absorber material. The nominal values of this absorber material shall be 80 percent silver,15 percent indium and 5 percent ca dmita. The silver-indium-cadmium control rods shall be clad with Inconel.
5.4 MAIN COOLANT SYSTEM DESIGN PRESSURE AND TEMPERATURE 5.4.1 The Stain Coolant System is de' signed and shall be maintained:
a.
In accordance with the code requirements specified in ASME Boiler and Pressure Vessel Code,Section VIII, including all addenda through 1956, and the ANSI (formerly ASI) Standards, Power Piping Code, B31.1, 1955 Edition, and B16.5, 1957 Edition, with allowance for normal degradation pursurnt to the applicable Sureelllance Requirements, b.
For a ressure of 2500 psig, and c.
For a temperature of 6500F, except for the pressurizer which is 6680F.
VOLUME 5.4.2 The total water and steam volume of the Main Coolant System is 2940 cubic feet.
5.5 METEOROLOGICAL TO'JER LOCATION 5.1.1 The meteorological tower shall be located as shown in Figure 5.1-1.
5.6 FUEL STORAGE CRITICALITY 5.6.1 The new and spent fuel storage racks are designed and shall be maintained with a center-to-center distance between fuel assemblies placed in the storage racks to ensure a k gg equivalent to -0.95 with the new or spent e
fuel storage areas flooded with unborated water. The keff of -0.95 includes a conservative allowance of 3%
k/k for uncertainties.
