The applicant should provide the classification of radiation zones within the reactor facility. The applicant should also provide the criteria and rationale for radiation zone designations, including zone boundaries during normal, refuelling and accident conditions. The application should describe how the zones are based on predicted dose rates, contamination levels, concentration of airborne radionuclides, access requirements, and specific requirements such as the need to separate safety trains. The application should describe how the rationale for zoning includes control of radiation exposures to conform to the ALARA principle, to prevent spread of contamination and to prevent or limit potential radiation exposures.
The information submitted should demonstrate that local rules for the zones have been established and described.
The application should describe the methods for radiation exposure and dose control, including policies and procedures that provide the basis for work instructions with the intent of ensuring radiation exposures and doses conform to the ALARA principle.
The applicant should provide the policy and procedures for radiation work planning and radiation work protection. The application should demonstrate that anticipated radiological hazards are also considered in the establishment of operating and maintenance procedures.
The applicant should provide the policies for radiation personal protective equipment (RPPE) and respiratory protection, which includes selection, use and maintenance.
The applicant should identify the equipment for radiation exposure and dose control.
The applicant should provide the action levels and their bases.
The description of the radiation protection program should include the criteria for selecting fixed, portable and laboratory technical equipment and instrumentation for:
· performing radiation and contamination surveys
· airborne radioactivity monitoring and sampling within the reactor facility
· area radiation monitoring
· monitoring of workers for normal operation, AOOs and accident conditions
The application should describe how the program will provide adequate quantities and types of equipment for anticipated needs in normal operations and emergencies, taking into consideration unavailability during calibration, maintenance and repair.
The application should describe the provisions for instrument storage, calibration and maintenance facilities. The application should include details on the frequency of calibration, the maintenance programs and the traceability of the instrumentation's usage. The application should also describe the calibration services for instrumentation, including how the service ensures traceability to a national standards laboratory.
In the radiation protection program, the application should include the policy for a radiation monitoring and survey program with provisions for:
· routine monitoring, which is conducted to demonstrate that the working environment is satisfactory for continued operations and that no change has taken place that would call for a reassessment of operational procedures
· task-related monitoring, which supplies information about a particular task or operation and to provide, if necessary, a basis for immediate decisions on the execution of the task
· special monitoring, such as during the commissioning stage for new facilities, following major modifications to either facilities or procedures, or when operations are being carried out under abnormal circumstances such as those following an incident or an accident
The application should describe the methods for monitoring and performing surveys, as well as the frequency, types and locations of the measurements to be performed.
The applicant should provide the policy for radiation monitoring and dose assessments for workers. The information should include details on monitoring procedures for workers, bioassays, and recording and reporting doses for workers.
The application should describe the contamination control program and its provisions for monitoring and decontaminating objects and persons in controlled areas, including storage areas for contaminated tools and other items.
The application should include the policy describing provisions for radiation protection during AOOs, DBAs and BDBAs/severe accidents. The application should include information on access controls, properly designed habitability controls, communications systems, adequate radiation monitoring capabilities, portable emergency response radiation protection equipment and instrumentation, and radiation personal protective equipment (RPPE), instrumentation and equipment.
The applicant should provide a policy for oversight of the radiation protection program, including, but not limited to, considerations of:
· management commitment
· assignment of responsibilities for quality assurance and oversight of the radiation protection program
· corrective action feedback into the radiation protection program
The applicant should provide a policy for conducting regular reviews of the radiation protection program. The application should include details on the frequency of, and the process for, conducting the review. The application should describe how procedures, equipment and facilities are improved when warranted.
The applicant should provide the policy for developing performance indicators (such as goals, objectives and guiding principles for their development).
The applicant should also provide details on which records are generated and the retention periods for those records.
