Dear Sir,
In keeping with its objective of providing clear and consistent information to the NRC, the Nebraska Public Power District (the District) has identified an example of submitted information that could potentially be misconstrued. In compliance with reference 2, CNS has been performing control rod withdrawal and insedion mobility checks as part of Startup Physics Testing. Since Reload 4, Cycle 5 in 1979, the District has submitted a Startup Physics Testing letter to the NRC which typically has included a discussion describing CNS compliance with the control rod mobility checks (see reference 1 as an example). The wording in the submittals leaves the impression that a mobility check will be performed prior to loading the next fuel bundle. In fact, it is only after the entire core is loaded that the control rod mobility checks are performed. This methodology is in keeping with the standard industry practice of performing this testing following core verification.
This issue was verbally communicated to Messrs. Phil Harrell and Terry Reis of NRC Region IV on April 4,1995, by the CNS Nuclear Licensing and Safety Manager. Investigations have revealed that Sections 1,2, and 3 of the associated attachments were recopied from submittal to submittal without critical review, most likely because the information regarding the Purpose, Description, and Criteria and Actions do not change between tests. A validation was performed for the remaining information, which was determined to be accurate and clear.
In reviewing this matter, it does not appear to have been the NRC's intent that Startup Physics Testing completion letters be submitted on a routine basis. Accordingly, the District intends to discontinue the submittal. The NRC should consider the Startup Physics Testing process to be
