15. Operational Safety
To confirm the applicability and quality of the operating procedures, they are verified to
ensure their technical accuracy, and are validated to ensure their usability with the
installed equipment and controls as far as possible prior to loading fuel into the core. This
process continues during the commissioning phase. This preliminary verification and
validation process also applies to maintenance, surveillance and chemistry procedures, as
appropriate.
The operating organization ensures that the commissioning program includes all the tests
necessary to demonstrate that the plant as installed meets the requirements of the FSAR,
satisfies the design intent, and consequently can be operable in accordance with the
LCOs. The tests are carried out in a logical order. Tests that may place the plant in a
condition that has not been analyzed shall not be performed. The program ensures that
system and component “base line” data, important to safety of the plant and for
subsequent safety reviews, is collected and retained.
From the start of commissioning, adequate work control and modification procedures are
implemented to ensure that the commissioning tests are not invalidated by subsequent
intervention on the plant. These procedures are the same as those intended for the
operating phase.
From construction to commissioning, and finally to operation, the plant is adequately
monitored and maintained in order to protect the equipment, support the testing phase and
continue to satisfy the SAR. Records of operations and maintenance are produced from
the initial energizing and operation of each plant system, and are retained by the
operating organization in proper archive facilities for periods as agreed with the
regulatory body.
