O s*SES:
This COMMITMENT is provided to ensure that groundwater levels will be monitored and prevented from rising to unacceptable levels. High groundwater levels could result in unacceptable structural stresses in the Containment and/or Auxiliary Building due to uplift and hydrostatic forces during design basis events. Although these buildings have been statically analyzed to withstand soil pressure along with the uplift and hydrostatic forces resulting from groundwater rebound to yard elevation (593'6"), this analysis did not include any other loadings and was not a design condition for these buildings.

BASES:
The OPERABILITY of the Fire Suppression Systems ensures that adequate fire suppression capability is available to confine and extinguish fires occurring in any portion of the facility where safety-related equipment is located. The Fire Suppression System consists of the water system, spray, and/or sprinklers, CO2, C
and fire hose stations. The collective capability of the Fire Suppression Systems is adequate to minimize potential damage to safety-related equipment and is a major element in the facility Fire Protection Program.
The proper positioning of RF/RY valves is critical to delivering fire suppression CO2 l
at the fire source as quickly as possible. The option of increasing or decreasing the l
frequency of valve position verification allows the ability to optimize plant operational resources. Should an adverse trend develop with CO Systems valve positions, the 2
frequency of verification shall be increased. Similarly if the CO Systems valve 2
position trends are positive, the frequency of verification could be decreased.
Through programmed trending of CO Systems as found valve positions, the CO 2
2 l
fire protection systems will be maintained at predetermined reliability standards.
The RF/RY System Engineer is responsible for trending and determining verification frequencies based on the following:
Initially the frequency will be monthly.
Annually review the results of the completed valve position verification procedures.
if the results demonstrates that the valves are found in the correct position at least 99% of the time, the frequency of conducting the valve position verification may be decreased from - monthly to quarterly or - quarterly to semlannually or-O CHAPTER 16.9-3 Page 3 of 4 05/05/99
O BASES (cont'd) semiannually to annually - as applicable. The frequency shall not be extended beyond annually (plus grace period).
if the results demonstrates that the valves are not found in the correct position at e
l least 99% of the time, the frequency of conducting the valve position verification l
shall be increased from - annually to semiannually or - semiannually to quarterly l
or - quarterly to monthly - as applicable. The valve position verification need not be conducted more often than monthly.

D.ASES (con't) minimum water volume at a minimum boron concentration, as presented in the CORE OPERATING LIMITS REPORT, is required from the boric acid storage tanks or the refueling water storage tank.
A minimum contained water volume r ad boron concentration, as presented in the CORE OPERATING LIMITS REPORT (COLR), is required to be available from the borated water sources in MODES 1,2,3, and 4. This volume is based on the required volume for maintaining SDM, unusable volume (to allow for a full suction pipe), instrument error, and additional margin for conservatism as follows:
Boric Acid Tank -
Required Volume for Maintaining SDM presented in the COLR Additional Margin (Unit 1) 854 gallons Additional Margin (Unit 2) 1,303 gallons Unusable Volume (to maintain full suction pipe) 7,230 gallons 14" of water equivalent Vortexing (4" of water above top of suction pipe) 2,066 gallons V
instrumentation Error (Based on Total Loop Acc. 1,550 gallons for 1 & 2 NV5740 loops)- 2" of water equivalent Refuelina Water Storaae Tank Required Volume for Maintaining SDM presented in the COLR Unusable Volume (below nozzle) 13,442 gallons Instrument inaccuracy 11,307 gallons Vortexing 13,247 gallons i
Additional Margin 3,504 gallons The contained water volume limits include allowance for water not available because of discharge line location and other physical characteristics.
