A summary of the evaluation of each, performed according to 10 CFR 50.59, is included. The determination was made that prior NRC approval was not required for these facility changes.
17-08-03 Remove Extension Building South Side of WTB An abandoned concrete block building extension (4'W X 4'D X 8'H) was dilapidated and in danger of collapse. The structure was removed from the south side of the Waste Treatment Building. The 50.59 screen, prepared in accordance with LACBWR Administrative Control Procedure (ACP) 06.4, "10 CFR 50.59 Evaluations," concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
19-07-25 Set Up Decon Area in Turbine Building Decon sinks removed from the Waste Treatment Building were used in establishing a larger, more easily accessible, and more functional decontamination area in the Turbine Building. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
51-07-03 Abandon Primary Purification Pump in Place The purification pump took suction through a nozzle appurtenance on the lower head of the reactor pressure vessel (RPV); the system returned filtered flow to 1B Forced Circulation Pump (FCP) loop. The RPV has been disposed of and FCP loop remnants have been filled with grout. The purification pump was electrically dismantled and abandoned in place awaiting mechanical removal at a later date. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
64-97-11 Remove Main Steam Equipment in Turbine Building Various piping and valves comprising the main steam supply to the turbine, including turbine inlet valves, were removed. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
74-07-83 Restore 120-V Receptacles and Lighting in Reactor Building For RPV disposal, bio-shield cutting and removal sacrificed some Reactor Building mezzanine level gallery lighting and 120-V receptacles. Temporary services were installed during the project. This change restored normal gallery lighting and receptacles. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.

74-08-85 Modify RB MCC Feeds MCA Trip The "Reactor Building MCA Feeds-MCA Trip" control switch, located on the Control Room benchboard provided the capability to de-energize the three 480-V AC motor control centers (MCCs) located in the Reactor Building. Maximum Credible Accident (MCA) was the equivalent of a loss of coolant accident (LOCA). Operation of the MCA Trip control switch, in accordance with the Operating Manual emergency procedure, was a required action in response to a major primary system leak. During MCA conditions, electrical sources in the Reactor (Containment) Building were de-energized prior to flood-up of the building with river water. These shunt trip functions were removed from the Reactor Building MCC feed breakers. One remote trip function, available from the Control Room switch, was maintained for the feed to a power disconnect used to supply the RPV removal lifting device. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
75-99-14 Remove Sprinkler Heads and Piping Sprinklers installed over the turbine oil tank obstructed dismantlement of the turbine oil system. Sections of the sprinkler system were removed to clear obstruction. This removal did not decrease the effectiveness of the Fire Protection Program. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
91-08-07 Replace 1B LPSW Pump 1B Low Pressure Service Water (LPSW) pump failed mechanically. The 3000-gpm pump was driven by a 150-hp, 2400-V AC, Allis Chalmers motor. Due to reduced LPSW system demand, the unit was replaced by a more economical 600-gpm, 40-hp, 480-V AC, Goulds pump and motor. The 50.59 screen, prepared in accordance with ACP-06.4, concluded that implementation of this facility change did not require prior NRC approval, that there was no need for any change to Technical Specifications, and that a 50.59 Evaluation per ACP-06.4 was not required.
TESTS There were no tests conducted during 2008.
EXPERIMENTS There were no experiments conducted during 2008.
