Independent Inspection Effort (Units 1 & 2)
The facility housekeeping in the Unit I auxiliary building and control building in the ESF switchgear areas was observed. Although debris was observed, ' the amounts were not excessive for construction and testing activities in progress..The in-place storage of unit 2 safety-related switchgear identified below was observed:
Auxiliary Building Switchgear (Elevation 119)
1.
480 volt motor control center (MCC) 26B11 2.
480 volt load center (LC) 2'3B3 3.
480 volt LC 26BB1 4.
480 volt LC 25BA3 Control Building Switchgear (Elevation Ill)
1.
4160 volt switchgear panel 25AA 2.
480 volt MCC 27B11 The auxiliary building switchgear was covered with internal space heaters energized.
The control building switchgear room was heated, and the i
switchgear was observed to have sufficient protection (e.g.,
glass on
'
maters and relays covered) for the construction and testing activities in progress.
Within the areas inspected, no items of noncompliance or deviations were identifie,

Electrical (Components and Systems I) Observation of Work and Work
,
Activities and Review of Quality Records The inspector selected Load Sequencing and Shedding panel number Q1H22P331 and Diesel Generator 21 Control panel number Q1H22P115 for inspection.
Installation instructions and inspection requirements are provided in Work Plan and Inspection Records (WP&IR) which are prepared in accordance with Bechtel procedure WP/P-1, " Establishment, Control and Implementation of the Construction Work Plan / Procedure Program". The inspector reviewed WP&IR number Q1H22-S-25A111-YO3 for panel P331 and W2&IR nshar Q1H22-P-12133-YO4 for panel P115. Panel installations were observed to be in accordance with the following Bechtel drawings.
Number Title C-0602A, R14 Unit 1 & 2 control Building Area 25A Reinforced Concrete, Floor Plan at El.111'-0" M-0013, R11 Equipment Location, Control Building Plan at El.93'-0",

Units 1 & 2 M-1026, R12 Equipment Location, Diesel Generator Building, Unit 1 C-1506C, R7 Unit 1 Diesel Gen. Bldg Area 12, Reinforced Concrete
'
Sections and Details E-1610, R3 Grounding Plans, Diesel Generator Building, Area 12, Unit 1 The Material Receiving Instruction and Inspection Report (MRI&IR) number 330E and the vendor certificate of compliance were reviewed for panel P331.
Both in-place panels were observed to be located in accordance with the above drawings.
Within the areas inspected, no items of noncompliance or deviations were identified.

Quality documentation reviewed included MRI&IR number NSSS-E22-IUC for the HPCS pump motor, MRI&IR number 129-M for the SSW pump B motor, MRI&IR number NSSS-S12-IUC for the RER pump B motor, and vendor certifications for all three pump motors. Although the installation of the HPCS pump motor was observed and appeared to meet requirements, the installa-tion was not verified against the WP&IR requirements.
The installations of the 480 volt m,.or operators for valves Q1P41F001A-A and QSP41F189-B were inspected for compliance with the valve Installation Card requirements.
The installation of motor operators for valves Q1G33F040-B and Q1E12F009-B was not observed due to the status of prepara-tions - for performance of the containment drywell integrity test (instru-mentation alignments were complete and containment lighting had been removed). Quality documentation reviewed included MRI&IR number 044 for valve operator Q1I41F001A-A, MRI&IR number 039 for valve operator Q1E12F009-B, and vendor certifications for valve operators Q1P41F001A and Q1E12F009-B.
Within the areas inspected, no items of noncompliance or deviations were identified.
