Operational skills

Operational skills

For the purpose of evaluation, it is necessary to identify the response strategies and the feasibility of establishing an action to cope with the incidents by taking into consideration the linkages of each field of the stress test execution guidelines, System-related facilities, procedures, organization / personnel, etc.), etc.
Evaluation items
◦ (6-1) Appropriateness of accident response strategy establishment
◦ (6-2) Appropriateness of major operator measures
◦ (6-3) Appropriateness of major resources
◦ (6-4) Ergonomic effectiveness
◦ (6-5) Ability to cope with multiple simultaneous accidents

Detailed instructions by item

◦ (6-1) Appropriateness of accident response strategy establishment
• Assessment of operational aspects of the accident scenarios established in Sector 3 (ability to respond to loss of safety functions such as power systems) and Sector 4 (serious accident management ability). Evaluation of the feasibility of the prepared accident scenario response strategy and the appropriateness of the linked items (facilities, procedures, etc.) for the established accident scenarios
- Considerations • The established accident scenarios consider each loss of essential coping skills and assess whether strategies are in place to restore them
- 32 -
• Essential coping functions are defined based on the safety-related functions considered in the Emergency Operation Procedures (EOP) and the Critical Incident Management Guidelines (SAMG). • A strategy for maintaining and recovering essential coping functions to respond to established accident scenarios. • Evaluate the appropriateness of linking items such as equipment, facilities, equipment, procedures, procedures, procedures, equipment, and organization / personnel to implement the response strategy for the established accident scenarios. ) Appropriateness of key operator actions
• Appropriateness and feasibility assessment of key operator actions derived from the analysis of accident scenarios established in paragraph (6-1), • Assessment of the adequacy of key operator actions derived through analysis of incident scenarios, Evaluating the feasibility of the operator measures. Identifying and evaluating possible human errors or decision errors in the process of successfully implementing the established incident response strategies.
- Considerations • Analyze and define the tasks required to implement the response strategy in the assumption of accident scenarios and assess the adequacy of the key operator actions necessary to perform the defined tasks. • Evaluate extreme situations (earthquake, fire, etc.) • assessing the feasibility of implementing key operator actions for the tasks required to implement a response strategy; and • assessing the available time to perform key operator actions and ensuring that they are sufficiently secured, assuming that major operator actions fail due to human error Establish alternative implementation plan • Identify possible human errors or decision errors that may occur when using facilities, procedures, etc. during accident scenarios to establish a minimization plan and propose measures to respond
- 33 -
◦ (6-3) Appropriateness of major resources
• Assessing the adequacy of key resources to carry out key operator actions derived from paragraphs (6-1) and (6-2), including human-system linkage facilities, procedures, organizations and personnel, operations Evaluation of appropriateness of tools, etc. Evaluation of appropriateness of education and training to ensure effectiveness of major operator measures Analysis and evaluation of resources, responsibility and authority necessary for decision making A rating
- Considerations • Human-system linkage facilities to perform key operator actions should be available in extreme situations (earthquakes, fires, etc.), including assumed accident scenarios, and alternatives should be available if not available • Perform key operator actions The procedures to be followed must be clearly defined and the linkage between each procedure and guidance document should be ensured. • Ensure that sufficient staff and personnel are available to carry out key operator actions derived from (6-2). • Ability to perform the functions of the operator, (Including specific scenarios, cycles, methods, and results) that are consistent with the responsibilities and responsibilities of each member • Identify the nature of the incident Analysis and procedures for the adequacy, responsibility and authority of the organization and manpower, And also establishing resource utilization strategy called alienation must check the suitability, sonae. Obtain skills necessary for running other coping strategies
- 34 -
◦ (6-4) Ergonomic effectiveness
• Assessment of operational skills, including the actual implementation of incident response strategies, key operator actions and resources (human-system linkage facilities, procedures, organization and personnel, etc.) established in view of accident scenarios. • Evaluate the appropriateness of the incident response strategy and check whether it is feasible • Evaluate appropriateness of the link items (facilities, procedures, etc.) for each field • Identify the possibility of human errors and decision errors through human engineering evaluation and evaluate countermeasures - Evaluate the assumptions of the accident scenarios and the appropriateness of the established incident response strategies and confirm the feasibility of their actual implementation. • Confirm the appropriateness of facility availability, site accessibility, environmental conditions and livability to implement the accident scenario response strategy. • In order to carry out the established accident response strategy, each item (facility, procedure, organization / manpower, etc.) • The result of the ergonomic effectiveness evaluation is ergonomically analyzed and evaluated and the improvement is derived. • The ergonomic validity evaluation stage is confirmed from the regulation side. (6-5)
Evaluation of feasibility of countermeasures even when considering simultaneous accident of multiple units. Evaluation of appropriateness of accident response strategy established considering consideration of simultaneous accident of multiple units. Assess the adequacy of available resources - Considerations • Incident response strategies should be able to be implemented even in the event of multiple simultaneous accidents involving extreme conditions. • In the event of multiple accidental accidents, if the incident response strategy changes, , Resources, and human error possibilities, etc. • In case of multiple simultaneous accidents, the responsibilities and authority between the incident response organizations may conflict.
