The use of probabilistic risk assessment to satisfy the Nuclear Regulatory Commission`s maintenance rule
- Massachusetts Inst. of Tech., Cambridge, MA (United States). Dept. of Nuclear Engineering
Maintenance and inspection at nuclear power plants consumes a large portion of a utility`s resources, making resource allocation for such procedures vital. The NRC Maintenance Rule, due to be implemented in July of 1996, requires utilities to select systems, structures, and components (SSCS) important to safety and to develop a monitoring program to ensure that these SSCs are capable of fulfilling their intended functions. In light of these concerns, two ratios were developed to compare the risk significance of individual components with the amount of plant staff time, or burden, associated with inspecting the component. These risk/burden ratios point out existing disparities between current inspection practices and safety concerns. These ratios can be used to develop new inspection schedules constituting a more equitable risk to burden distribution.
