Pursuant to 10CFR 50.90, Northeast Nuclear Energy Company (NNECO) hereby proposes to amend Operating License NPF-49 by incorporating the attached proposed revision into the Millstone Unit No. 3 Technical Specifications Surveillances 4.1.2.3.1, 4.1.2.4.1, 4.5.2.f and 4.5.2.h.
Description of Proposed Revision Technical Specification Surveillances 4.1.2.3.1, 4.1.2.4.1, 4.5.2.f and 4.5.2.h require the centrifugal charging and safety injection pumps be tested on a periodic basis and after modifications that alter subsystem flow characteristics. The proposed revision to these specifications includes an increase in the required differential pressure at recirculation flow for the safety injection and centrifugal charging pumps, a decrease in the required individual safety injection and centrifugal charging pump injection line flow rates, an increase in the allowed individual safety injection pump total flow rate, and editorial changes to the surveillances.
Markup of Proposed Revision A copy of the marked up Technical Specification pages is contained in Attachment 2.
The markup reflects the currently issued version of the Technical Specifications.
Pending Technical Specifications revisions or Technical Specification revisions issued subsequent to this submittal are not reflected in the enclosed markup.
Retype of Proposed Revision A copy of the retyped Technical Specification pages is contained in Attachment 3. The retyped pages reflect the currently issued version of the Technical Specifications.
