3.7.13

' The groundwater level of the service water reservoir (shared by Units 1 and 2)l shall not exceed the elevation at the locations listed in Tabis 3.74. The flow of groundwater f

from the drains beneath the pumphouse shall not exceed the values phen in Table,3.7 ,

l APPUCABluTY: ALLMODES.

i

! MIX 2$:

1 i a. With the groundwater level of the servios water reservoir or the groundwater flow rate esosoding any of the Amits of Table 3.74. an engineering evaluation l l

i shall be performed by a Uconsed Civl Engineer to determine the cause of the high 1

gmund water or flow rates and the influence on the stablRty of the service water j reservoir and pumphouse. A Special Report shat be prepared and submitted to the '

Commission pursuant to SWetion 6.9.2 within 90 clays, containing the resuhs of the evaluation and any corrective action determined to be necessary.

- b. With the inabNty to obtain at least one measurement from each of the locations l listed in SR 4.7.13.1, an engineering evaluation shaR be performed by a Ucensed Ckt Engineer to determine 4he consequences of not meeting <

l Special Report shal be prepared and submitted to theission Comm.SR

( pursuant4.7.13.1.

to A i

1 Specification 8.9.2 within 90 days, containing the results of the evaluation and i 1 any corrective action determined to be necessary.

c. The provisions of Specification 3.0.4 are not appDesble.. .

~ SURVEILLANCE REQUIREMENTS j

! 4.7.13.1 ,

At least once per six months verify the groundwater level within the dka of the i

service water reservoir does not exceed the value established in Table 3.7-6.

The groundwater level shan be determined by measurement imm eadt zone. At a j .

minimum, at least one measurement shaR be made at each zone Asted bebw and .

the measurement shaN be within the Amits presented in Table 3.74

1 l

= service water pump house (Nos.11,14 or 20), and

acuth east end of the reservoir (Nos. 10,15,21 or 22), and

+ a$rvice water valve house (Nos.18 or 19) 4.7.13.2 At least once per six months vertfy that the groundwater flow rate does not exceed the value estabashed in Table 3.74. The groundwater flow rate shan be -

determined by measurements at the drain outlet gallery. A visual inspectbn of the clartty of the outflow from each drain shaR be performed in conjunction with the flow monhoring effort.

. A program a monitor groundwater levels in the area of the service water reservoir has

been establisned to ensure that the. integrity of the service water reservoir embankments ard pumphouse is maintained.

1 .

i i Groundwater threshold levels have been established based on historical groundwater da j available in 1977. These levels are sufficiently conservative to ensure that the service water reservoir and pumphouse wOl perform their intended function. An engineering evaluatbn will i

be performed if these threshold values are exceeded, to determine if there is any substantive ) '

i cause to believe that any aspect of the service water reservoir, dke, or pumphouse wm not j perform its intended furetion. A conclusion to this effect and the appropriate corrective actbns to be performed, wul be reported to the Commission.

A minimum of one measurement device 'n each of the three zones is required to be l j OPERABLE in order to monitor the groundwater levels. The groundwater levels are p i

^

reviewed to determine whether a changing groundwater erwironment warrants a change in l threshold levels.
