RNO: Notify WCC SRO to initiate Encl 5.2 (Primary Leak Check) and of the leak area (AB or RB), if known 4.7 Initiate Encl 5.1 (Leak Rate Determination). (This will calculate RCS leakage based on CC surge tank level increase and is a very gross calculation since there is no OAC point for CC surge tank level and therefore control room gage must be used.

NOTE:

• CC Surge Tank is hard piped to overflow to LAWT.

• Chemicals from the CC system will rapidly exhaust demineralizers used to process LAWT water. Radwaste has limited storage capability and a Rx shutdown may be required if the leak CANNOT be isolated.

SRO /BOP 4.17 IAAT CC Surge Tank level is off-scale high, THEN notify Radwaste that the CC Surge Tank has overflowed to the LAWT.

4.18 IAAT RCS leakage is flashing the CC system, OR threatens to overflow the LAWT, THEN perform the following: N/A at this time NOTE RCS to CC leakage may be indicated by one RCP cooler outlet temperature increasing more than the others (use historical temperature trend) near the time of increase on 1RIA-50.

4.19 Verify leakage indicated by change in RCP cooler outlet temperatures (Turn-on code "GD AP02"): (No leakage indicated)

RNO GO TO Step 4.24 NOTE RCS leakage to CC in the letdown coolers may be indicated by a cooler outlet temperature increasing more than the other cooler. Due to CC system setup, letdown cooler CC outlet temperatures may be different. A historical OAC temperature trend may be required to determine if leakage exists and if actions taken are successful in leak isolation. If leaking cooler CANNOT be identified, the coolers will be isolated one at a time starting with the 1A Letdown Cooler.

4.24 Monitor letdown cooler outlet temperatures to determine which cooler is leaking (Turn-on code "GD AP02"):

• O1A0065 (LETDOWN COOLER 1A CC OUTLET TEMP)

• O1A0066 (LETDOWN COOLER 1B CC OUTLET TEMP) 4.25 GO TO the appropriate step to isolate affected cooler:

• The following alarms actuate due to the RCP trip:

• 1SA-7/D8

• 1SA-2/A3

• 1SA-2/A5

• FDW flow will begin to re-ratio but the delta Tc failure will not allow correct re-ratio

• Actual TC to increase (become more negative).

• NIs will begin to slowly diverge until Tcs are restored to normal.

• Tech Specs: Failure to adjust FDW flow will result in QPT alarm (1SA-4/C1) approximately 4 minutes following the failure. This will eventually result in entry into TS 3.2.3 if incore tilt exceeds allowable value. It may also result in PZR level > 260 which is entry into TS 3.4.9.

Crew Response:

OATC/BOP

• Crew should perform Plant Transient Response (PTR)

• Diagnose the TC failure by observing the TC meter on 1UB1. It should return to zero but is staying at + 3.5 degrees.

Total feedwater flow should be maintained constant while individual loop flows are adjusted to establish the desired Tc. Maintaining total FDW flow constant will prevent unwanted changes in reactor power.

3. Notify SPOC to perform the following:

__ Investigate and repair the failed Delta TC controller BOOTH CUE: When notified to investigate and repair the failed TC controller, respond as SPOC and state that the TC controller will be repaired as soon as possible.

If RCS bora tion is for a Forced Outage, targeted boron should not exceed 200 ppm above the required SDM to prevent excessive RCS boration. The 200 ppm above required SDM will borate the Pressurizer to the required SDM since the Pressurizer usually lags the RCS by approximately 200 ppm.

• 50 gal of DW added due to flushing must be included in determination

• Volume required ____________gallons.

2.2 CBAST required volume approved (SRO). (R.M.)

NOTE:

Placing an idle Letdown Filter in service can change RCS boron by adding 60 gals of w aterto RCS at different boron (negligible for RCS boration). {10}

1. Stabilize RCS Temperature BOP/OATC

2. Notify WCC to secure all primary draining/RB washdown evolutions if applicable.

NOTE Depending on leak location, leakage may NOT be detected by all the formulas. One or more of the following methods may be necessary to determine RCS leak rate.

3. Calculate leak rate using the following, as required:

Examiners Note: There are several other methods to calculate leakage rate. While one of the two below will most likely be used, depending on plant conditions they may not be the only correct methods available.

Method #1: Calculation of RCS Volume Loss:

Leak Rate = ______ + ______ - ______ - ______ = ______

MU SI LD TSR Where: MU = makeup Flow SI = Seal Inlet Hdr Flow LD = Letdown Flow TSR = Total Seal Return Flow Method #2: LDST Level Change:

Leak Rate = (LDST level change) x (31 gal/inch) + BTP Flowrate (gpm)

(minutes)

Leak Rate = ( inches) x 31 gal/inch + ______ gpm = _________ gpm

_____minutes

4. Notify OSM and SRO of calculated leak rate.

This event is complete when the 1B RBCU is started or as directed by the lead Examiner.
