4.4 Training of operations staff
Training in nuclear criticality safety shall be provided with due consideration of the nature of the work operations stall perform and the sensitivity of that work in maintaining nuclear criticality safety.
Operations staff working according to procedures that are required to maintain nuclear criticality safety will require a greater extent of training than those staff who do not perform those duties or those who perform tasks that are intrinsically less sensitive for maintaining nuclear criticality safety.
EXAMPLE Staff In a facility handling inventories of multiple critical masses, with nuclear criticality safety based on administrative control of batch sizes, will typically require a higher level of training than a facility handling small fractions of a critical mass.
The scope and the level (depth) of training shall be formulated to enable the operations staff to operate a process with sufficient understanding of the criticality hazards associated with that process, and the importance and reasons behind the controls identified to maintain nuclear criticality safety.
Understanding the reasons behind the controls may reduce the risk of operations staff deviating from procedures and/or responding inappropriately to unexpected process conditions. Analysis of past criticality accidents and near-miss data has revealed a number of instances where inadequate understanding of the reasons behind the criticality safety controls has been a contributory factor.
4.5 Training of operations supervisors
Certain roles are particularly important in maintaining nuclear criticality safety. A supervisory role to operations staff is one such role, as are those roles responsible for making decisions which could significantly affect nuclear criticality safety (e.g. operations manager or shift team leader). These key safety roles are termed collectively in this document as operations supervisors (as defined in 32).
It is necessary for operations supervisors to have a more comprehensive understanding of the nuclear criticality safety issues and their significance. This could include understanding of typical or common themes that have caused criticality accidents and the need to maintain systems to monitor, maintain and improve nuclear criticality safety in a facility. The specific content of the required training is discussed in
Operations supervisor training shall be in addition to the identified training for operations staff and should be biased to the particular nuclear criticality safety issues associated with the process for which they have responsibilities.
4.6 Training of management
Management shall have an awareness of the severity of the consequences of nuclear criticality accidents and, hence, of the importance of a suitable nuclear criticality safety program.
Management have overall responsibility for the nuclear criticality safety of operations for a site, process or facility and define the nuclear criticality safety program. Management do not require detailed nuclear criticality safety training because they do not carry out operations and, therefore, rely on operations supervisors and operations staff to maintain day-to-day criticality safety.
5 Role in the training program
5.1 General
Subclauses 5.2 to 5.7 define the roles of operations staff, operations supervisors, management, nuclear criticality safety staff, the training coordinator, and the trainer in the nuclear criticality safety training program.
5.2 Operations staff
Operations staff shall attain a level of understanding of nuclear criticality safety consistent with the nature of the work they carry out, as defined by the operations nuclear criticality safety training program.
5.3 Operations supervisors
NOTE These responsibilities are in addition to those defined in ISO 14943.
Operations supervisors shall consult with the nuclear criticality safety staff to identify operations staff requiring nuclear criticality safety training.
Operations supervisors shall confirm, via the criticality trainer(s), whether operations staff have attained sufficient understanding of nuclear criticality safety prior to allowing commencement of activities for processes that may present a criticality hazard.
Operations supervisors shall attain a level of understanding of nuclear criticality safety consistent with the nature of the work they carry out, as defined by the operations nuclear criticality safety training program.
5.4 Management
NOTE These responsibilities are in addition to those defined in ISO 14943.
Management shall ensure the establishment and maintenance of an operations nuclear criticality safety training program. This shall include the requirement for training for operations staff, operations supervisors, and management.
Management shall consult with the nuclear criticality safety staff to identify operations supervisors requiring additional nuclear criticality safety training, beyond that identified for operations staff (as identified in Clause 6).
Management shall confirm, via the criticality trainer(s), that operations supervisors have attained sufficient understanding of nuclear criticality safety prior to them assuming responsibility for processes that may present a criticality hazard.
Management shall attain a level of understanding of nuclear criticality safety consistent with the requirements of the operations nuclear criticality safety training program.
5.5 Nuclear criticality safety staff
Nuclear criticality safety staff should develop and maintain the nuclear criticality safety training materials for operations staff, operations supervisors, and management.
5.6 TrainIng coordinator
The training coordinator should assist and advise in the development and delivery of the nuclear criticality safety training materials, in consultation with the nuclear criticality safety staff and criticality trainer(s).ISO 23133 pdf download.
