In this report, the staff of the US Nuclear Regulatory Commission provides a regulatory analysis for the proposed resolution of Generic Issue 153 (GI-153), ``Loss of Essential Service Water in LWRS.`` GI-153 deals with the concerns pertaining to the reliability of essential service water (ESW) system and related problems for all light water reactors except the seven multi-unit sites addressed by GI-130. ``Essential Service Water Pump failures at Multi-Unit Sites.`` On the basis of the technical findings of a scoping study for GI-153, the staff recommends that the insights gained from the study serve as a complement to the on-going ESW performance inspection program. The staff also concludes that ESW system reliability is being addressed by various on-going regulatory programs. Therefore, the staff recommends that GI-153 should be considered ``RESOLVED.`` The need for future action(s) on ESW reliability is expected to be determined from these on-going programs.
