Fort Calhoun request for additional information regarding license amendment to revise method for controlling raw water intake cell level during floods (MF2591)
Mr. Hansher and Mr. Edwards, By letter dated August 13, 2013 (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML13231A178) Omaha Public Power District (OPPD) submitted a license amendment application to revise the method for controlling raw water intake cell level during floods. The U.S. NRC staff has reviewed the information provided in your August 13, 2013, license amendment request and determined that additional information is required in order to complete its review. These requests for additional information (RAIs) can be found below.
A draft RAI was transmitted on June 5 and 6, 2014, and it was determined by OPPD that a clarification call was not needed.
Please provide a response to these RAIs by July 11, 2014. Should the NRC determine that the RAIs found below are no longer necessary prior to the dates found above, the request will be withdrawn. Please contact me if circumstances result in the need to revise the requested response date. Please treat this e-mail as formal transmittal of the RAIs.
