This Technical Report provides guidance on the handling of setpoints for sequenced actions in both nuclear safety-related and nuclear power plant non-safety-related instrumentation.

Purpose

The purpose of this Technical Report is to supplement the information provided in ANSI/ISA-S67.04-Part I-1994, Setpoints for Nuclear Safety-Related Instrumentation, and ISA-RP67.04-Part II-1994, Methodologies for the Determination of Setpoints for Nuclear Safety- Related Instrumentation, for the performance of instrument uncertainty calculations and instrument setpoint determinations. Specifically, the topics addressed in this Technical Report expand on the discussion of Sections 7 (Establishment of Setpoints) and 9 (Interfaces) of ISA-RP67.04, Part II.
