The Ventilation and EQ environmental conditions in the areas that contain the critical equipment, which is relied upon by the operators, and in the areas where operators will require access, has been evaluated via review of existing calculations and/or development of new calculations. These areas include: Primary Containment, Secondary Containment, Control Building (Control Room and Battery Rooms), and RCIC Pump Room. Equipment operability and habitability are confirmed for all the concerned areas. To protect station personnel from the adverse effects of performing FLEX related mitigation actions in thermally elevated environments, an evaluation of the plant areas requiring access for mitigation actions was performed and compensatory actions or restrictions were identified and incorporated into procedures. The detailed response for this item has been provided on the ePORTAL for NRG staff review.

NRG Audit Report NMP2 is located on the southeastern shore of Comglete Open Item AQ 20 (SE Lake Ontario, which is the ultimate heat sink for Tracker Item 20-B) - the plant.

When faced with the choice. of injection of low quality water or no injection, the action will always be to inject low quality water which is consistent with EPRI Severe Accident Management Guidance Technical Basis Report (EPRI Report 1025295) Volume 2, Section DD.

NMP2 EOPs require that injection sources be selected based on core and debris cooling requirements, reliability, resource requirements, effects on other severe accident response strategies, and the quality of the water source.

Raw water sources should generally be used only as a last resort. If other systems become available, injection lineups should be shifted to higher quality sources to minimize use of raw water. This strategy will ensure cooling for at least 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after commencing injection from the UHS. During this time, Nine Mile Point will develop recovery methods that will utilize a clean source of water. The recovery methods could i.nclude transition back to the reactor water grade sources, arranging for clean water sources, or other methods to filter water prior to injecting into the core. The detailed response for this item has been provided on the ePORTAL for NRC staff review.
