In what areas is the REA responsible?

The selected answer highlights the responsibilities of the Reactor Electrician (REA) in ensuring the operation, care, and maintenance of reactor electrical and propulsion plant electrical systems. This is a critical role because the REA is integral to maintaining the safety and efficiency of the reactor and its electrical components.

The REA must possess a deep understanding of how the electrical systems interact with reactor operations, including monitoring and troubleshooting any issues that arise. This encompasses everything from routine inspections and preventative maintenance to ensuring that systems are operationally ready during drills and actual operations. Proper functioning of these electrical systems is essential for the overall safety and performance of the propulsion plant and reactor.

In contrast, the other options focus on narrower or unrelated aspects. For instance, being responsible only for instrumentation systems does not encompass the full breadth of the REA's responsibilities, which include both power generation and distribution for propulsion. Maintenance of reactor control systems, while important, is just one aspect of the broader scope that includes electrical systems. Lastly, financial management of reactor operations is outside the technical scope of the REA's duties, as this role primarily involves hands-on technical skills rather than financial oversight. Thus, the focus on the comprehensive operation and maintenance of reactor electrical systems in the correct response aligns perfectly with
