SUBJECT:

WESTINGHOUSE 10CFR70.72 FACILITY CHANGE REPORT Westinghouse Electric Company LLC (Westinghouse) hereby submits the report of Columbia Fuel Fabrication Facility (CFFF) changes that did not require Nuclear Regulatory Commission (NRC) pre-approval in accordance with 10CFR70.72.

This report addresses those changes completed within calendar year 2017. Westinghouse had no facility changes that required NRC pre-approval during this time period.

Westinghouse uses an integrated safety review approach for all modifications of, or additions to, existing structures, systems and components at the CFFF.

This process is described in, and conducted in accordance with the requirements of CFFF Regulatory Procedure RA-104, "Regulatory Review of Configuration Change Authorization." This integrated review is conducted by the various regulatory disciplines, including Nuclear Criticality Safety, Radiation Safety, Environmental Protection, Safeguards, Fire Safety, Chemical/Industrial Safety and other applicable Health and Safety experts when necessary. A key aspect of this review is a determination that the change is not prohibited by 10CFR70, a SNM-1107 license condition, or a governing order. The reviewers also determine whether NRC pre-approval and SNM-1107license amendment changes are required prior to implementation.

Specific guidance is provided to ensure that NRC pre-approval is obtained for changes that:

create new types of accident sequences that, unless mitigated or prevented, would exceed the performance requirements of 10CFR70.61 and that have not previously been described in the Integrated Safety Analysis (ISA) Summary; use new processes, technologies or control systems for which the licensee has no prior expenence; remove, without at least an equivalent replacement of the safety function, an Item Relied On For Safety that is listed in the ISA Summary and is necessary for compliance with the performance requirements of 10CFR70.61; or alter any Item Relied On Safety, listed in the ISA Summary, that is the sole item preventing or mitigating an accident sequence that exceeds the performance requirements of 10CFR70.61.

Each of the changes identified in the attachment to this correspondence were evaluated in accordance with this RA-104 procedure, and a determination was made that NRC pre-approval of the respective change was not required.

Replace P-3A with a 5 HP pump, and relocate it further from P-3B.

Remove abandoned Line 4 PLC cabinets and associated conduits and wiring.

Remove tank agitator and blind off nozzle/plate where agitator entered tank. Replace recirculation dip leg with drip tip.

Replace the decanter frame and housing on conversion line 2.

Remove the existing acetone dispensing station across the aisle from the new ECG machine area near column 15A.

Remove the out of service access ladder by line 4 in the ADU Rod area and install the new aluminum counter balanced ladder.

Justification Current welded valves are leaking. This CCF will update these valves to the new style used in the scrap area.

Pump condition is degrading. Relocation would make future P-3B replacement easier.

Equipment is out of service.

Agitators are not necessary to produce a homogenous UN solution and require inspection and repair (require confined space entry) and are not sealed, so that FME could enter the tank.

The frame is corroding.

The existing acetone dispensing station is too close to the gas fired heater on the corner over the aisle near column 15A and will be too close to the new ECG machine.

Panel required for Line 3 press installation per CCF 16086.

The current lubrication grease for the hot oil dryer bearings was found to be of poor quality.

Current controllers are obsolete.

The addition of these controls will provide defense-in-depth in the active engineered control systems for hydrogen deflagration mitigation.

The consultant performing the annual Boiler inspection recommended we increase the size of the PSV stack drains.

This access ladder was removed from service. The replacement ladder will provide safety features the out of service ladder did not have.
