This document applies to the reactor physics tests that are performed following a refuelling or other
core alteration of a PWR for which nuclear design calculations are required. This document does not
address the physics test program for the initial core of a commercial PWR.
This document specifies the minimum acceptable startup reactor physics test program to determine
if the operating characteristics of the core are consistent with the design predictions, which provides
assurance that the core can be operated as designed.
This document does not address surveillance of reactor physics parameters during operation or other
required tests such as mechanical tests of system components (for example, the rod drop time test),
visual verification requirements for fuel assembly loading, or the calibration of instrumentation or
control systems (even though these tests are an integral part of an overall program to ensure that the
core behaves as designed).
