SUPPLEMENTARY INFORMATION:

I. Background

Draft regulatory guide DG-1141 describes practices and criteria that the staff of the NRC considers acceptable for compliance with NRC requirements for ensuring that setpoints for safety related instruments are initially within, and should remain within, technical specification limits. This DG also presents practices and criteria for establishing those technical specification limits and ensuring that those limits will adequately support the proper operation of the associated systems—that is, that establishing and maintaining setpoints in accordance with those limits will provide adequate assurance that a plant will operate as described in the plant safety analyses.

II. Public Meeting

The public meeting will be held in North Bethesda, Maryland, at 11601 Landsdown Street in conference room 1C05 of the 3 White Flint North building adjacent to the White Flint metro station.
