Relationships of Process Hazard Analyses to Other DOE Required Hazard Analyses cont'd

are met, the resulting analysis should significantly contribute to the analysis required under the

DOE-STD-1027-92 (CH-1) for release mechanisms. However, analyses beyond PSM Rule

requirements may be needed to comply with other SAR requirements for Nuclear Hazard

Category 2 Facilities.

NUCLEAR HAZARD CATEGORY 1 FACILITIES.

Fault tree/event tree analyses are required if the

facility is a large reactor. If the facility is not a reactor and a PSM Rule PrHA is required, the

analyses can be conducted as described for Nuclear Hazard Category 2 Facilities. Different

systems or processes within the facility may be analyzed using different methods. For example,

HAZOP studies may be used as the PrHA method for processes that contain chemical hazards.

Fault tree/event tree analyses may be used to analyze systems that do not need to comply with

the PSM Rule.

All documents required by the PSM Rule should be referenced and their significant findings

summarized in the SAR. References and summaries should include not only the results of the

PrHA, but also all documents concerning the resolution of the PrHA team's findings.
