The index is still subject to potential revisions, but should they occur, they can be expected to be sufficiently rare and small for the US ruling on this issue to be acceptable where bonds are indexed to the first published figure for each monthly HICP. This methodology works well in the United States, where CPI-U is also exposed to revision risk. ...

Siting, both location and layout, is critical for inherently safer plants. Evaluate siting with respect to the risk imposed by the process on the population, environment, adjacent facilities, and community. These evaluations apply to small revisions as well as major new processes. 

After the hazard assessment has been conducted and the data has been collected, it should be organized in a logical outline that will estimate the potential for employee injury The organized data will help to decide the type of hazard(s) involved, the level of risk, and the seriousness of potential injury The appropriate levels of PPE are then selected based on the hazard determination and the availability of PPE. The user should be properly fitted for the specified PPE, and the employer should make sure that it is comfortable to wear. Hazard reassessments should be conducted as necessary based on the introduction of new or revised processes, equipment, and accident experience, to ensure the continued suitability of selection of the proper PPE. 

In May 1988, a Level-1 PSA was undertaken as part of the general risk assessment at DOE facilities. Revision 0 was completed, and reviewed by BNL, DOE and contractors. The revised report was available July 1990 (Azarm, 1990). The broad objective of the HFBR PRA program is to enhance the safety and operational activities throughout the. remaining lifetime of the reactor...
