Control Rod Scram Timing System Implementation

This document is a case study detailing the implementation of a new Control Rod Scram Timing (CRST) application at a single-unit boiling water reactor (BWR) nuclear power plant in the Midwestern United States. The objective of the project was to upgrade the scram time system as part of a broader modernization initiative. The CRST application enables end-to-end data tracking and automated calculations, significantly reducing testing times while minimizing human error and enhancing worker productivity. The case study outlines the importance of scram time testing as a safety procedure, describing how control rods are used to manage the nuclear fission reaction and prevent accidents. It also discusses the integration of the CRST software with existing systems, including a new plant process computer and transient timing system, and highlights the successful completion of the project during the COVID pandemic. The document concludes with an assessment of the results and outcomes of the CRST implementation, emphasizing its role in monitoring scram timing and improving operational efficiency.
