. A Global Energy Company December 15,1998 GDP 98-0269 Mr. Robert C. Pierson Chief, Special Projects Branch Division of Fuel Cycle Safety and Safeguards, NMSS U.S. Nuclear Regulatory Commission Washington, D.C. 20555-0001 Paducah Gaseous Diffusion Plant (PGDP)
- Docket No. 70-7001 Monthly Update on Progress of Seismic Upgrades to Buildings C-331 and C-335
Dear Mr. Pierson:
In accordance with USEC's commitments in our April 15,1998 letter (Reference 1), the purpose of this letter is to provide the monthly update on the progress of the installation of the seismic upgrade modifications to Buildings C-331 and C-335.
An update on the progress of the C-331 and C-335 seismic modifications was provided to the NRC in a telephone call between Dr. Carl Paperiello (NRC) and Mr. George Rifakes (USEC) on October 29,1998, following an evaluation of the overall project conducted by consultants retained by USEC.
As discussed in that call, USEC has determined that the seismic upgrades to these buildings cannot be completed by June 30,1999 as required by Issue 36 of DOE /ORO-2026," Plan for Achieving Compliance With NRC Regulations at the Paducah Gaseous Diffusion Plant" (the Compliance Plan).
p Construction activities in the buildings have proven to be substantially more diflicult than originally anticipated. In numerous locations, a significantly greater than expected effort has been required to remove and relocate interferences, remove existing steel, and install the new steel. These /[/,c unanticipated difficulties, coupled with the reduced worker productivity experienced in the high heat conditions of the process buildings, are projected to more than double the original estimated cost of the project and will result in a delay of approximately 12 months in the overall construction schedule.
A Certificate Amendment Request has been prepared to modify the Plan of Action and Schedule associated with Compliance Plan Issue 36 to reflect a revised date of June 30,2000 for completion of the seismic modifications in Buildings C-331 and C-335. USEC submitted this Compliance Plan change to the Department ofEnergy (DOE) for approval on December 11,1998 (Reference 2). Two l-weeks following receipt of the DOE letter approving the changes to Compliance Plan Issue 36, USEC
. will submit the associated Certificate Amendment Request to the NRC for approval.
