Description:

TC Controller Fails HIGH (A Loop Hot)

Time Position Applicant's Actions or Behavior SRO/OATC Plant Response:

• FDW flow will ratio incorrectly based on the failure

• A FDW flow will increase causing A loop TC to decrease.

• B FDW flow will decrease causing B loop TC to increase.

• This will cause actual TC to increase (become more negative). Failure to adjust FDW flow will result in QPT.

• 1SA-02/B-5, RC Cold Leg Diff. Temperature High, will actuate if actual TC increases to +/- 5°F

• 1SA-02/B-9 MS STM GEN A LEVEL High/Low will actuate when SG Operating Level is 86%

Crew Response:

• 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.

• Take the Diamond and Feedwater Masters to MANUAL and re-ratio feedwater using the Loop TC meters and/or OAC (RCS01) to return actual TC to near zero.

• SRO should direct the BOP to reference Statalarm 1SA-02/B-5

• SRO will refer to AP/28 (ICS Instrument Failures) 4.1 Provide control bands as required (per OMP 1-18 Attach I) 4.2 Initiate notification of the following:

4.6 GO TO the applicable section per the following table:

Section Failure 4F Delta TC AP/28 Section 4F NOTE This section applies to Delta TC controller failures. TC input signal failures are addressed in Section 4A The following may occur when an ICS Delta TC controller fails:

Delta TC controller may re-ratio loop FDW flows Possible ICS RUNBACK

1. Ensure the following in HAND:

__ 1A and 1B FDW MASTERS

__ DELTA TC CAUTION 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.

2. Re-ratio feedwater flow, as required, to establish desired DELTA TC while maintaining total feedwater flow constant

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.

4. WHEN notified by SPOC that DELTA TC controller has been repaired, THEN GO TO OP/1/A/1102/004 A Encl (Placing ICS Stations To Auto)

NOTE: ICS will remain in manual for the remainder of the scenario.

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.

1B MSLB outside the reactor building Time Position Applicant's Actions or Behavior OATC/BOP Rule 8 (as directed by Rule 5)

EXAMINER NOTE: Neither of the criteria in the note below are met so no actions are required in Rule 8. If the crew pulls Rule 8 as directed by Rule 5, they should immediately EXIT back out based on the note at the beginning.

NOTE This rule is invoked under either of the following conditions:

• A cooldown below 400°F Tc at > 100 °F/hr has occurred.

• HPI has injected through an open or throttled open 1HP-26, 27, 409, 410 with all RCPs OFF.

SCM must be minimized. The following methods may be used at the discretion of the CR SRO:

• Throttling HPI per Rule 6 (HPI)

• De-energizing Pzr heaters

• Using Pzr normal spray

• Using Pzr aux spray

• Using PORV

• Throttling LPI {22}

Once RCS temperature is stable, a 1-hour hold of RCS temperature must be performed unless a LOCA or SGTR is in progress. Use Tc in loop with an operating RCP or use CETCs if NO RCPs are operating.

Once invoked, SCM shall remain minimized until Engineering has performed an evaluation and determined that PTS restrictions NO longer apply. Starting RCPs and/or restoring cool down rates to normal values do NOT negate the need for this evaluation.
