REFERENCE:

(1) NRC Letter, Eisenhut to Linder, dated January 1, 1980

Dear Mr. Eisenhut:

We have inspected all safety related and non-safety related electrical equipment to determine that positive anchorage exists (load carrying mechanism other than friction). The following list of electrical equipment within the Containment Building was inspected and we have determined that positive anchorage does exist: (1) In Core Flux Drive System: Bolted and welded to steel grouted in floor. (2) Reactor Building Motor Control Center lA: Bolted and welded to steel grouted in floor. (3) Control Rod Drive Gas Readout Panel: Bolted to floor. (4) Shield Cooling Pumps: Bolted and grouted in floor. (5) Portable Hoist: Bolted and welded, has rail stops. (6) Control Rod Drive Mechanism: Bolted to pressure vessel. l [ 8006050 DO {

1 Mr. Darrell G. Eisenhut, Acting Director LAC-6960 Operating Reactors Branch #2 May 30, 1980 (7) Seal Injection Pump Motors: Bolted and grouted in floor. (8) Air Conditioner Units lA and 1B: Bolted to floor. (9) Emergency Core Cooling Pumps lA and 1B: Bolted to frame grouted in floor. (10) Motor Control Center IC, 1B: Bolted and welded to steel grouted in floor.- (11) Fuel Storage Well Pump 1A and 1B: Bolted to frame grouted in floor. The following list of e_ cctrical equipment within the Turbine Building and inspected and we have determined that positive anchorage does exist: '(1) 480-Volt lA and 1B Switchgear: Bolted to steel grouted in 1 floor. (2) 1A and 1B Gwitchgear Transformers: Welded to steel grouted in floor. (3) Unit Auxiliary Transformer: Bolted to steel grouted in floor. (4) Resistor Bank: Bolted to floor anchors. (5) Demineralizer Panel: Welded to steel grouted in floor. (6) Laundry Equipment Transformer: Bolted to floor anchors. (7) Turbine Building Motor Control Center 1B, 1C, 1D, lE: Bolted and welded to steel grouted in floor. (8) Laundry Equipment: Bolted to floor anchors. (9) Auxiliary Building Transformer: Bolted to wall steel supports to "I" beam. (10) All Auxiliary Miscellaneous Motors: Bolted to steel grouted in floor. (11) Generator Switchgear: Bolted to steel grouted in floor. i

Mr. Darrell G. Eisenhut, Acting Director LAC-6960 Operating Reactors Branch #2 May 30, 1980 The following list of electrical equipment within the Electrical Room beneath the Control Room was inspected and we have determined that positive anchorage does exist. (1) Generator Plant Battery Rack: Floor mounted and bolted to wall. (2) Reactor Plant Battery Rack: Bolted to floor. (3) Generator Plant Battery Charger: Bolted to floor top conduit supports. (4) Reactor. Plant Battery Charger: solted to floor top coaduit supports. (5) Reactor Relay Panel: Bolted to floor. (6) 1A, 1C, Small Inverters: Bolted to wall. (7) Turbine Building Motor Control Center lA: Bolted to floor. (8) Control Room Air Conditioner: Bolted to floor. (9) Generator Plant Protective Relay Panel: Shock mounts bolted to floor, upper panel support shock mounts bolted to wall. The following list of electrical equipment within the 1B Electrical Equipment Room was inspected and we have determined that positive anchorage does exist.- (1) 480-Volt Essential Switchgear lA and 1B: Bolted to steel grouted in floor. (2) 1B Inverter: Bolted and welded to steel grouted in floor. (3) 1B Battery Charger: Bolted and welded to steel grouted in floor. (4) Electrical Switchgear: Bolted and welded to steel grouted in floor. (5) 1B Battery Rack: Bolted to floor. (6) 1B Diesel Generator Control Panel: Bolted and welded to steel grouted in floor. f

Mr. Darrell G. Eisenhut, Acting Director LAC-6960 Operating Reactors Branch #2 May 30, 1980 A vertical control panel is one continuous unit bolted section to section and floor supported. The panel is bolted to shdek mounts that are welded to steel grouted to the floor.. The upper section is back supported by bolted shock mounts to wall. The benchboard control panel is one continuous unit bolted section to section and floor supported-the panel is bolted to shock mounts that are welded to steel grouted to the floor. Other miscellaneous motor control centers located in the Crib House and the Waste Treatment Building are bolted and welded to steel grouted in the floor.

1980, Regarding Seismic Design Evaluation for Anchorage and Support of Safety Related Electrical Equipment.

(2) DPC Linder to Eisenhut, dated May 30, 1980, LAC-6960, (attached). (3) Sargent & Lundy Standards EB-122, 133, 135; EE-138, 142, 173; EF-241, 246, 248, 249; EB-686 (attached). In addition to the inspection conducted in mid May 1980, for evidence of positive anchorage of. electrical equipment, the following items listed in the NRC IE Information Notice No. 80-21 were inspected. (1) Emergency Diesel Generator lA and 1B Room Heaters consist of a metal frame bolted to anchors in concrete wall. (2) Emergency Diesel Generator Start Batteries in metal frame bolted to anchors in concrete wall and floor. (3) Emergency Diesel Water Pump Start Batteries in metal frame bolted to wall and anchors in concrete floor. (4) Cable Trays are secured by unistrut bolted to "I" beams or threaded rod secured to "I" beams or anchored to concrete. (5) Instrument Air System Dryers are bolted and grouted to the concrete floor. Upper end supported by piping. By my observation and the review of the Sargent & Lundy Standards which governed the installation of our equipment, the components at the LACBWR seem to be well anchored. WRN: abs
