Who may carry out an investigation of an accident involving a power plant?

The Chief Inspector of the jurisdiction plays a critical role in the oversight of safety and regulatory compliance in power plants. This answer is correct because the Chief Inspector is typically authorized to conduct investigations into accidents in facilities under their jurisdiction, including power plants. Their responsibilities often include evaluating incidents to ensure that safety regulations are adhered to and determining the root causes of any accidents in order to prevent future occurrences. This regulatory authority is crucial for maintaining safety standards and protecting both workers and the public.

In many jurisdictions, safety oversight is delineated in specific regulatory frameworks, which empower the Chief Inspector to conduct these investigations. This guarantees that there is a designated authority that has the necessary expertise and responsibility for understanding the complexities of power plant operations.

The other options lack specificity regarding the authority and responsibilities for accident investigations. Some do not address the regulatory framework that necessitates such investigations, while others downplay the Chief Inspector's crucial role in ensuring safety and compliance in power plant operations.
