NUREG-1432, Standard Technical Specifications for Combustion '

j Engineering Plants, Revision 0, September 1992 In Reference (a), Baltimore Gas and Electric Company (BGE) requested an amendment to the Technical Specifications for Calvcit Cliffs Unit Nos. I and 2 which would revise the Design Features section of the Technical Specifications.

Following discussions with the Nuclear Regulatory Commission Staff, BGE has agreed to withdraw the proposed climination of the " Control Element Assemblics" and " Drainage" paragraphs. The existing paragraphs will be retained and renumbered as required by the other proposed changes.

The proposed "Fuct Assemblies" section of the Design Features was based on Revision e of NUREG-1432 (Reference b). It contains the statement, "Each assembly shall consist of a matrix of zirecnium alloy fuel rods with an initial composition of natural or slightly enriched uranium dixoide (UO ) as fuel ma'erial."

10 CFR 50.46, " Acceptance criteria for emergency core cooling systems for light water nuclear power I

reactors", provides for use of cylindrical zircaloy or ZIRLO as a fuel cladding in light water reactors. The proposed Revision 1 of NUREG-1432 replaces the phrase " zirconium alloy" with the phrase " cylindrical ~

zircaloy or ZlRLO". For consistency with the regulations and the proposed Revision 1, BGE revises our L

proposed change to incorporate that phrasc.

In Reference (a), BGE proposed to replace the " Site" section and eeW~i maps with a new wrian, " Site Imition" which describes the leath of the site in ad,cc with SectSn 182.a of the Atomic Energy Act. In our discussions, the NRC has stated that the " Site Le*6" section must contam the minunum Exclusion Area radius to be acceptable. This informaten is not currently included in the Calvert Cliffs Technical Specifications Based on the request by NRC Staff and a need to expedite apprent and issuance of this amendment to support our upcommg refueling outage, we have included the Exclusion Area boundary reference. Inclusion of this reference, however, appears to represent a new requirement wliich we j

would reconsider as part of any future submittals to improve our Technical Specifications.

j Attachments (1) and (2) include revised " Insert A" pages for AM-Wents (1) and (2) of Reference (a).

'Ihe proposed revisions to Reference (a) do not change the " Determination of Significant Hazards" section of that submittal.
