4.8 Probabilistic Risk Assessment
For those facilities for which a Probabilistic Risk Assessment (PRA) has been performed, initial
and continuing training programs should include the principal results of the PRA. The training
should address the following:
C
The importance of facility systems in preventing damage or severe accidents
C
The probabilistic basis for defining magnitudes and compositions of potential releases
of radionuclides (or other toxic materials) and consequences of potential releases in
terms of facility worker and offsite population health effects
C
Dominant types of potential operational accidents as defined in terms of frequency and
consequences
C
Locations of all significant amounts of radioactive and other hazardous materials, and
measures to prevent their release
C
The importance of maintaining operational limits and conditions, and the consequences
of violating those limits
C
Identification of potential hardware failures and human errors which constitute dominant
contributors to important accident sequences
C
The role PRA can play in optimizing operating limits, Technical Safety Requirements,
testing, and maintenance intervals
C
The role of external events such as earthquakes, extreme winds, flooding,
transportation accidents, etc., in terms of their contribution to facility risk
C
The role PRA can play in evaluating proposed changes in operating procedures or
equipment configuration.
4.9 Nuclear Safety
A goal of operations of DOE facilities is that operation will not result in any significant impact
on the health and safety of the public, facility employees or contractors, or the environment.
Therefore, STA trainees should receive training in the following areas:
C
Nuclear criticality safety limits
C
Nuclear materials safeguards
C
Limiting conditions of operation
C
Safety envelope
C
Facility Safety Analysis Report
C
Technical Safety Appraisals
C
Safety analysis and review system
C
DOE Nuclear Safety Policy Statement
C
DOE orders relating to nuclear safety
C
Applicable NRC regulations relating to nuclear safety
C
Operating experience.
