SUBJECT:

Calvert Cliffs Nuclear Power Plant Unit Nos. 1 & 2; Docket Nos. 50-317 & 50-3 18 Additional Information Concerning the License Amendment Request: Extension of Diesel Generator Required Action Completion Time (TAC Nos. MB8976 and MB8977)

(a) Letter from Mr. P. E. Katz (CCNPP) to Document Control Desk (NRC),

dated May 12, 2003, License Amendment Request: Extension of Diesel Generator Required Action Completion Time (b) Letter from Mr. K. J. Nietinann (CCNPP) to Document Control Desk (NRC), dated February 23, 2004, Response to Request for Additional Information Concerning the License Amendment Request: Extension of Diesel Generator Required Action Completion Time (TAC Nos. MB8976 and MB8977)

In our letter dated May 12, 2003 (Reference a), we requested a License Amendment that would extend several Required Action Completion Times for inoperable diesel generators. During a pre-implementation review, we determined that the original marked-up Technical Specification Insert 4 does not accurately reflect the discussion in Reference (a). Changes to the original marked-up Insert 4 are necessary so that it reflects and supports the extension of the diesel generator Required Action Completion Times requested in Reference (a) as modified by Reference (b). Specifically, Insert 4 should have included an additional statement that allowed the Control Room Emergency Ventilation System, Control Room Emergency Temperature System, and H2 Analyzer to be declared inoperable after 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. This change will support the discussion found on page 6 of Attachment 1 of Reference (a).

Attachment (1) contains the revised Insert 4. Attachment (2) contains new final pages that reflect the revised Insert 4.

This information does not change the conclusions of the No Significant Hazards Consideration Determination or the Environmental Impact Review provided in Reference (a).
