7. RIC's place in operating specifications

7.1 Flow card execution requirements

A flow map is required in three main cases.

The first is the need to verify that the core conforms to the design calculations. To this end, complete flux maps are produced during physical restart tests after redivergence (neutron tests), and then on a monthly basis during the cycle.

Two points are of particular interest: the verification of the absence of loading errors by means of a flux map taken at 8% PN, and the verification of the evolution of core hot-spot factors as a function of exhaustion, by means of a series of flux maps run every month at nominal power.

The second is the calibration of external power distribution instrumentation, i.e. the determination of sensitivity...
