The Region and NRR staff have been involved in the assessment of D.C. Cook Unit 1 and 2 containment structural issues since March 2000. The operability of the D.C. Cook Unit 1 and 2 containment structures was reviewed by NRR staff as a part of the Manual Chapter 0350 process. Following the restart of both Units, the licensee continued to perform transient mass distribution (TMD) and structural calculations to determine conformance with the design basis. The licensee made a presentation to NRR staff on June 11, 2001, regarding their determination that containment structures met design basis requirements. However, during the meeting the licensee did not provide detailed information regarding calculation assumptions, and Unit 2 walkdowns to verify as built dimensions used in the calculations had not been completed. The licensee completed the walkdowns in September 2001, and finalized their calculations in late November 2001.
