Comparisons between the extensive radiological measurements made during start up of units I and II of the CNAAA NPP

Integrated tests (IT) applied to the Units I and II of the CNAAA NPP (Angra dos Reis, Rio de Janeiro) were part of the comprehensive test programme to which the plants were submitted before authorization for commercial operation is issued. The so called IT tests included operation at zero power and subsequent power levels (the power escalation) until the nominal operation power. This paper reports and compares the results of systematic neutron and gamma dose-rate measurements performed inside and outside the reactor containment of the units, during the start-up phase of the operation of the plants, for different power levels of the reactors.
