I MO: 08031738000 ORIGINAL @ Category 70 POSITIVE COMPONENT VERIFICATION:
REQUIRED OBSERVABLE BEHAVIOR STEPS As requested in the craft surveys, in order to increase compliance and effecLiveness in conducting positive component verifications (PCV's),
the below required observable behavior steps have been included in the MO/CWO as an aide.
These steps should be performed PRIOR to performing work on equipment, components, or terminations.
See S0123-I-1.43 "Maintenance Human Performance Application" for complete PCV program requirements and labeling exceptions.
A.
PRIOR TO LOCATTtG EQUIPMENT IN FIELD (TYPICALLY DONE DURING PRE-JOB BRIEF):
Step 1: 'IDENTIFY TARGET ID'
- Write down the "Target ID" on the PCV Tracking Record (Attachment 8 of S0123-I-1.43) or MO/CWO.
Step 2:
'VERIFY CORRECT ID' Compare written "Target ID" with the "MO/CWO Equipment ID" to validate that the "Target ID" was written correctly.
B. AT JOB SITE:
Step 3:
'LOCATE EQUIPMENT'
- With the MO/CWO in hand, compare the "Target ID" to the component-identifying label using verbalization (point-shout-shoot).
Step 4:
'WRITE EQUIPMENT ID'
- Write down the component-identifying label "EquipmenL ID" near previously written "Target ID".
Step 5: 'INITIAL & DATE' Compare the written down component-identifying label "Equipment ID" with the "Target ID" and initial and date if the ID's match exactly (See S0123-I-1.43 for approved labeling exceptions).
If the ID's do not match exactly, STOP and contact the work supervisor to resolve in accordance with Procedure S0123-I-1.43.
C. SECOND COGNIZANT EMPLOYEE:
Step 6:
'SECOND-PERSON SELF-CHECK'
- A second person should repeat Step 3 and initial signifying agreement that the intended component has been positively identified.
(Note: The responsible supervisor may waive the second-person self-check based on a SAFER evaluation.)
08031738-0 Page 3
MO:1 08031738000 ORIGINAL @ Category 70 WORK PLAN DETAIL:
The correct equipment/component must be positively identified prior to performing any work.
THIS M.O.
IS ON EQUIPMENT WHICH REQUIRES RECORDING OF M&TE USE AS DESCRIBED IN S0123-XV-1
'CALIBRATION AND CONTROL OF MEASURE AND TEST EQUIPMENT'.
DWGS/REFS:
EQ REFS:
None POSITIVE COMPONENT VERIFICATION The specific steps of performing Positive Component Verification should be repeated for each task:
- When conducted by different worker,
- After an extended break from work,
- When the level of distraction is high,
- When working in Skill-Base or Rule-Base performance modes, Or as directed by the work supervisor.

NUCLEAR ORGANIZATION UNITS 1, 2 AND 3 MAINTENANCE PROCEDURE REVISION 7 S0123-1-2.3 PAGE 23 OF 50 TCN 7-1 6.10.3.1.2 As much as possible, wipe the narrow space between the adjacent Jar Covers.
.1.3 Clean the Jar Cover. Be careful NOT to smear the Cover with the NO-OX-ID grease at f Battery Terminals.
.2 Record Cell Numbers showing age inthe MO.
Cc 6.10.4 If necessary, clean visible corrosion from the Battei
..nections and coat with NO-OX-ID Special Grade "A" Grease.
Nr 6.11 Restoration 6.11.1 Verify the following:
.1 All Measuring and Test Equipment have been removed from the Battery Cells.
.2 All dust covers, cell caps, and flame arresters are installed.
.3 Verify equipment remaining in the Battery Room is seismically restrained.
.4 All Inter-cell dust covers are installed.
(b)(6)
INT:
NT:
.5 Have a second person verify the conditions listed above, 2nd Pom ITW NOTE:
If performing this procedure to satisfy the prerequisites of a Battery Service Test, Procedure S0123-1-2.5, or a Battery Performance Test, Procedure S0123-1-2.6, do NOTperform Steps 6.11.2 through 6.11.2.3.1 6.11.2 Notify the Engineer. An MO MAY be initiated to perform an Equalize Charge if one of the following conditions exist:
SNOTIE:
Verity low or abnormally high Specific Gravity readings by triple dipping.
( Read Specific Gravity at the top, middle, and bottom of the cell to determine the Average Specific Gravity).
.1 If one or more Cell's Corrected Specific Gravity is more than 0.010 below the average of all cells at the time of inspection,
.2 If the Average Corrected Specific Gravity of all cells: < 1.205,
.3 If one or more individual Cell Voltage ( ICV ) is:
_ 2.14 VDC.
