Letter from Mr. G. Vanderheyden (CCNPP) to Document Control Desk (NRC), dated December 12, 2003, License Amendment Request: Revision to the Technical Specifications to Support the ISFSI NUHOMS-32P Upgrade (b) 10 CFR 72.214, List of Approved Spent Fuel Storage Casks, Certificate Number 1004 (c)

Telecon with NRC staff, May 26, 2005 By Reference (a) we submitted a license amendment request to incorporate Technical Specification changes to support the Calvert Cliffs Independent Spent Fuel Storage Installation (ISFSI)

NUHOMS-32P Upgrade. In that request we indicated that for Technical Specification Surveillances 4.2.1.1 and 4.2.1.2 increasing the initial verification of boron concentration from "within one hour" to "within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />" was consistent with the provision for verification of boron concentration approved for the NUHOMSO general license. The approved surveillance time for NUIHOMS0 general license is four hours (contained in Certificate Number 1004, Reference b).

Per our telecon with your staff (Reference c), we propose to increase the surveillance time from "within one hour" to "within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />" consistent with the provision for verification of boron concentration approved for the NUHOMSO general license. This letter supersedes our proposed revision to Technical Specification Surveillances 4.2.1.1 and 4.2.1.2 in Reference (a). The Technical Specification marked-up page contained in Attachment (1) supersedes the marked-up page provided in Reference (a).

APPLICABILITY Applicable to all DSCs.

ACTION:

1.

With the measured boron concentration less than the specification prior to the beginning of DSC loading and unloading operations, suspend all activities involving DSC loading and unloading.

2.

With the measured boron concentration less than the specification during DSC loading and unloading operations, take action to increase boron concentration while. unloading fuel from the DSC.

SURVEILLANCE REQUIREMENTS ot 4.2.1.1 Within rpriorto insertion bf the first spent fuel assembly into a DSC, the dissolved boron concentration in water in the spent fuel pool and introduced. into the DSC cavity shall be independently determined by chemical analysis (two samples analyzed by two different individuals). The boron concentration in the water shall be reconfirmed at intervals not to exceed 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> until such time as the DSC is removed from the spent fuel pool.
