1.0 SCOPE

EFFECTIVE DATE

PROCEDURE CLASSIFICATION: QUALITY RELATED

1.1 This test provides instructions for the calibration of RefuelingWater Storage Tank (RWST) 1-1 water level channel.

1.1.1 Affected Loop: 9-1.

1.1.2 Affected Devices: LT-920, LQ-920, LC-920A/B, LC-920C/D,LM-920, LI-920, and ERFDS 03/08.

1.1.3 PME Indicator (Ref MA2.ID2): LI-920.

1.2 This test satisfies the L-920 CHANNEL CALIBRATION specified inTS 4.3.3.6, Tbl 4.3-7, Item 8.

1.3 This test may be performed in any Mode subject to the conditionsstated in the Prerequisites Section.

2.0 DISCUSSION

2.1 Devices included in this test collectively function to provide:~ One input to Residual Heat Removal (RHR) Pump trip 2 out of 3

coincidence.~ Control Room and ERFDS indication of RWST 1-1 water level.~ Control Room alarm of RWST l-l High, Low, and Low-Low water

level.

2.2 This test is structured such that it allows for the independentcalibration of the transmitter and electronics.

2.2.1 Section 8.3 performs a calibration of the transmitter.

2.2.2 Section 8.4 performs a calibration of the electronics.

3.0 RES PONS IB ILITIES

3.1 Cognizant Foreman (Test Director) is responsible for performanceand initial management review of this test.

5.1 If "As Found" data for LT-920 or LI-920 are out-of-tolerance dueto an apparent module failure, then notify your Supervisor andinitiate an AR. "As Left" data for these devices shall be withindesired.

5.2 If "As Found" data exceeds a "TS or ECS OOT" accuracy, then notifyyour Supervisor and initiate an AR. "As Left" data for same shallbe within desired.

5.3 If "As Found" data exceeds a "PME OOT" accuracy, then theSupervisor to report IAW MA2. ID2. "As 'Left" data for thesedevices, as well as LM-920, shall be within desired prior to useof this channel for PME purposes.

5.4 Other Administrative Requirements for "As Left" Data

ERFDS and LC-920ClD shall be within desired.

5.5

5.6

Acceptance Criteria for this test are denoted in the InstructionsSection by use of asterisks (*). If "As Found" actions do notoccur as desired, then notify your Supervisor and initiate an AR."As Left" actions for same shall be within desired. IData not denoted as Acceptance Criteria is desired. The TestDirector may return the channel to service with "As Left" data outof desired provided there is no significant degradation of,overallloop function and an AR has been generated to document the action.

6.2 Job Preplanning

6.2.1 Applicable Technical Specifications - TS 3.3.3.6 andTS 3.5.5.

6.2.2 Indication/alarm functions provided by this loop.

6.2.3 One input to RHR Pump trip 2 out of 3 coincidence isprovided by this loop.

7.0 PRECAUTIONS AND LIMITATIONS

,

7.1

7.2

Transmitter Calibration (Section 8.3) requires that RWST LOW LEVELTRIP TEST LS-920 Switch be in the CUT OUT position. One input tothe RHR Pump trip 2 out of 3 coincidence will be defeated duringthe performance of this section.

One input to the RHR Pump trip 2 out of 3 coincidence will be madeup during part of the Analog Channel Calibration (Section 8.4).
