WebJul 1, 2001 · In the framework of safety analysis for the Belgian nuclear power plants and for the reload compatibility studies, Tractebel Energy Engineering (TEE) has developed, to define a 95/95 DNBR criterion, a statistical thermal design method based on the analytical full statistical approach: the Statistical Thermal Design Procedure (STDP). WebFuel cladding integrity shall be maintained by ensuring that the minimum departure from nucleate boiling ratio ( DNBR) remains above the 95/95 DNBR limit for PWRs (a 95% probability at a 95% confidence level) and that the critical power ratio (CPR) remains above the minimum critical power ratio (MCPR) safety limit for BWRs. fleet optics edmonton
