Dear Mr. Spina:

resubmitted Relief Request Nos. ISI-020 and ISI-021 for the Calvert Cliffs Nuclear Power Plant, Unit No.2. The proposed relief requests would decrease the frequency of inspections by extending the American Society of Mechanical Engineers Boiler Pressure and Vessel Code (ASME Code),Section XI inservice inspection interval from the current 10 years to 20 years for ASME Code,Section XI examination Categories B-A and B-D reactor pressure vessel welds.
The letter also withdrew Relief Request Nos. ISI-020 and ISI-021 included in your application dated May 1, 2008 (ADAMS Accession No. ML081230381), that proposed deferring the subject weld examinations for one fuel cycle.
The purpose of this letter is to provide the results of the Nuclear Regulatory Commission (NRC) staff's acceptance review of these relief requests. The acceptance review was performed to determine if there is sufficient technical information in scope and depth to allow the NRC staff to complete its detailed technical review. The acceptance review is also intended to identify whether the application has any readily apparent information insufficiencies in its characterization of the regulatory requirements or the licensing basis of the plant.
Pursuant to Sections 50.55a(a)(3)(i) and 50.55a(a)(3)(ii) of Title 10 of the Code of Federal Regulations (10 CFR), the applicant shall demonstrate that the proposed alternatives would provide an acceptable level of quality and safety, or that compliance with the specified requirements of Section 50.55a would result in hardship or unusual difficulty without a compensating increase in the level of quality or safety.
The NRC staff has reviewed your application and concluded that it provides technical information in sufficient detail to enable the staff to proceed with its detailed technical review and make an independent assessment regarding the acceptability of the proposed amendment in terms of regulatory requirements and the protection of public health and safety and the environment. If additional information is needed for the staff to complete its technical review, you will be advised by separate correspondence.
