Core Operation, experiments and code validation
Abstract
In the first decade of June 2008, during the power commissioning of the reactor at Mohovce NPP unit 1, the experiment with reducing the thermal power of core almost to the balance-of-plant (BOP) needs was performed. After the reactor has operated for seven hours at low power (about 200(220 MW (thermal)), its power was increased (at a rate of about 0.25% of Nnom/min) to the initial level, close to 107% (1471 MW).
