Subject:

Response to NRC Bulletin 96-02; Movement of Heavy Loads Cooper Nuclear Station, NRC Docket No. 50-298, License No. DPR-46

References:

1) NRC Bulletin 96-02, dated April 11,1996, " Movement of Heavy Loads Over Spent Fuel Pool, Over Fuel in the Reactor Core, or Over Safety-Related Equipment"
2) NUREG 0612, dated July 1980, " Control of Heavy Loads at Nuclear Power Plants"
3) Letter to J. M. Pilant (NPPD) from D. Vassallo (NRC), dated October 31, 1983, " Control of Heavy Loads (Phase 1)"

Gentlemen:

Pursuant to the requirements of 10 CFR 50.54(f), the Nebraska Public Power District (District) hereby submits to the Nuclear Regulatory Commission (NRC)its response to NRC Bulletin 96-

02. As required by the bulletin, the District has reviewed its plans and capabilities to handle heavy loads over spent fuel, fuel in the reactor core, or safety-related equipment while the reactor is at power and currently scheduled to be moved within the next two years from the date of the bulletin. The District has determined that its plans and capabilities to handle these heavy loads are in accordance with the existing regulatory guidelines, and that these activities are within its licensing basis. At this time, no changes to the Cooper Nuclear Station's (CNS's)

Technical Specifications are required.

Because the medes excluded from the scopo of the bulletin (cold shutdown, refueling, and defueled) do not precisely correlate to the plant modes defined in the CNS Technical Specifications, the District has interpreted the scope of the bulletin for CNS as applying to heavy loads being moved during the Run Mode, Startup/ Hot Standby Mode, and Shutdown Mode where the station is not in Cold Shutdown (reactor coolant temperature equal to or less than 212' F and the reactor vessel vented). The attached table describes the movement of heavy loads within the scope of this bulletin anticipated within the next two years.

  • As discussed in Reference 3, the Reactor Building crane, Intake Structure crano, and Control Building hoist (H-7) are all subject to the guidelines of NUREG-0612 (Reference 2). Other load handling devices have been excluded from the guidance of NUREG-0612 because either no safe shutdown / decay heat removal equipment or irradiated fuel is

- located in proximity of the device, or the load handling device's sole purpose is to provide

, a maintenance function such that a load drop will damage only equipment which is already out of service for maintenance.

  • The NRC has accepted our response to Phase I to NUREG 0612 in the Safety Evaluation Report (SER) per Reference 3.
  • The District has no plans to lift loads greater than those already analyzed in the Updated Safety Analysis Report (USAR) using the cranes subject to NUREG 0612 guidelines (see attached table).
  • The District currently has no plans to move loads in excess of the analyzed limits (e.g.,

dry storage casks such as those used at Oyster Creek) over spent fuel.

Should you have any questions or require any additional information, please contact me.
