Sažetak
IRIS (International Reactor Innovative and Secure)is a modular,small/medium size (335 MWe)PWR with integral vessel configuration.IRIS satisfies key requirements associated with advanced reactors,including improved safety, enhanced proliferation resistance,competitive electricity production cost,and improved waste management. Maintenance is optimized in such a way that opening the reactor pressure vessel (RPV)is required not sooner than every four years.Therefore,cycles of four years with full fuel reload are being developed.The resulting improved capacity factor and reduced manpower for maintenance/reload contribute to favorable cycle economics.IRIS design aims at significantly reducing soluble boron concentration to simplify related systems.Additionally,requirements resulting from a four-year straight-burn core design are notably more complex than those resulting from present 12- month or 18-month PWR cycles.To address these requirements,enhanced burnable absorbers (including IFBA,Er,Gd, and their combinations)were evaluated.Standard code systems based on nodal diffusion theory were employed to evaluate various core design alternatives,while modeling of novel fuel features was additionally benchmarked via Monte Carlo based simulations.The paper will discuss neutronics analyses and present preliminary core configurations that are being developed to satisfy the design requirements.
