Resolution of Generic Safety Issues: Task HF7: Human Reliability (Rev. 2) ( NUREG-0933, Main Report with Supplements 1–35 )

The primary purposes of this task are to develop a technical support system for NRC reliability evaluations, especially the PRA programs, and to provide feedback links from operating experience to other elements of the human factors program. A secondary goal is to develop approaches for employing human error data as baseline performance measures in man-machine safety system evaluations.

ITEM HF7.1: HUMAN ERROR DATA ACQUISITION

DESCRIPTION

Staff stated in the Supplement to NUREG-0933 published in 1986 that ongoing and planned activities were designed to provide NRC reliability evaluation programs with methods and techniques for acquiring reliable human error data from a variety of nuclear power related sources. Significant research involved developing guidelines for acquiring human error data from expert judgment, training simulators, operating nuclear power plants using LER data, and from a non-punitive reporting concept.

This item is related to increasing knowledge, certainty, and understanding of safety issues in order to increase confidence in assessing levels of safety and is, therefore, considered a licensing issue.

CONCLUSION

As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,1967 that the Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues. Because licensing and regulatory impact issues are not safety issues by the classification guidance in the legacy Generic Issues Program, these issues do not meet at least one of the Generic Issues Program screening criteria and do not warrant further processing in accordance with Management Directive 6.4, "Generic Issues Program," dated November 17, 2009.1858 Therefore, this issue will not be pursued any further in the Generic Issues Program.

ITEM HF7.2: HUMAN ERROR DATA STORAGE AND RETRIEVAL

DESCRIPTION

Staff stated in the Supplement to NUREG-0933 published in 1986 that activities were designed to provide the NRC with a human reliability data bank for use in processing human error data for use by reliability evaluation specialists. Planned activities included developing methods and procedures for computing human error probability statements from diverse information sources and storing, updating and retrieving human error probability statements and related information.

This item is related to increasing knowledge, certainty, and understanding of safety issues in order to increase confidence in assessing levels of safety and is, therefore, considered a licensing issue.

CONCLUSION

As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,1967 that the Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues.

ITEM HF7.3: RELIABILITY EVALUATION SPECIALIST AIDS

DESCRIPTION

Staff stated in the Supplement to NUREG-0933 published in 1986 that that a comprehensive and accurate analysis of human behavior sequences leading to recognition, diagnosis and reaction to nuclear power station normal, transient and emergency events was necessary for risk assessment. Analytic techniques and methods for portraying adequately the human segments of those events were needed, especially events involving redundant or interdependent actions by individuals or groups. Also needed were techniques for analyzing cognitive and performance shaping factor (e.g., stress, fatigue, attitude) aspects of human behavior. Significant research activities in this area involved: (1) developing techniques for analyzing safety-related events, especially those involving redundancy and/or interdependent actions; and (2) investigating the feasibility of objectively analyzing cognitive and performance shaping aspects of human behavior within the content of NRC reliability evaluation programs, especially PRAs.

This item is related to increasing knowledge, certainty, and understanding of safety issues in order to increase confidence in assessing levels of safety and is, therefore, considered a licensing issue.

CONCLUSION

As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,1967 that the Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues.

ITEM HF7.4: SAFETY EVENT ANALYSIS RESULTS APPLICATION

DESCRIPTION

The PRAs are a potential source of quantitative and qualitative human performance data, both generic and plant-specific. Staff stated in the Supplement to NUREG-0933 published in 1986 that human reliability research would be directed toward developing and testing approaches and techniques for systematically using human performance data from PRAs to: (1) identify generic and plant-specific man-man and man-machine safety system retrofit requirements, (2) establish objective baseline performance measures for evaluating plant retrofits, and (3) identify future human reliability/human factors research needs.

This item is related to increasing knowledge, certainty, and understanding of safety issues in order to increase confidence in assessing levels of safety and is, therefore, considered a licensing issue.

As a part of the improvements to NUREG-0933, the NRC staff clarified in SECY-11-0101, "Summary of Activities Related to Generic Issues Program," dated July 26, 2011,1967 that the Generic Issues Program will not pursue any further actions toward resolution of licensing and regulatory impact issues.
