Set point calculations for RAPID project

The Respond and Pump in Days (RAPID) project was initiated to pump part of the contents of tank 241-SY-101 into tank 241-SY-102. This document establishes the basis for all set points and ranges used in the RAPID project. There are 23 instrument and/or control loops utilized by the RAPID project. These range from the simple indication loop with two components to complex indication, control, and alarm loops with up to eight components. Several loops include safety class elements. This document is intended to describe the loops in full and to provide the basis for each of the element setpoints, ranges and accuracies identified in the RAPID project Master Equipment List (MEL). These values are developed in two steps. First, the base value is identified with reference to the supporting document providing that value. Second, a spreadsheet calculation is performed on each element and loop, utilizing a standard methodology described below, that takes into account known and suspected variance in output and establishes the actual setpoint used on a given element. The results of the spreadsheet are reported directly in this document
