Upon review of two documents, Attachment 10 to the 11/01/13 submittal titled, NEDC-33576NP, Safety Analysis Report for Nine Mile Point Unit 2 Maximum Load Line Limit Analysis Plus, and, attachment to
the 02/14/14 submittal titled, Response to NRC Request for Supplement Information in Support of NMP2 MELLLA+ LAR Acceptance Review, the staff has the following requests for additional information:
RAI # APHB-1: Please describe any operator manual actions that will be added, deleted, or changed to support the proposed license amendment, including reductions in time available to complete the actions.
RAI # APHB-2: Please quantify the reductions in time available for operator actions and provide the process used to validate that all necessary human actions can be reliably completed within the available time.
RAI # APHB-3: Please provide the NRC with any operating experience that was used in this proposed change. These may include but are not limited to plant-specific condition reports, Licensee Event Reports, INPO reports, prior implementations of the MELLLA+ design, and other relevant sources.
RAI # APHB-4: As a result of the implementation, please describe any changes to the procedures, training documents, displays, and simulator referred to on page 89/119 of the submittal.
RAI # APHB-5: Will any changes to the Safety Parameter Display System be required? If yes, describe.
==================================
The NRC staff would like to receive the responses to the RAIs within 30 days from the date of this communication. Please contact me, ASAP, to schedule a telephone conference between the licensee and the NRC staff to ensure that the licensee clearly understands the RAIs and also, to obtain a firm commitment/ confirmation from the licensee for the Responses to these RAIs.
