This paper presents an overview of the first 10 years IRIS project, summarizing its main technical achievements and evaluating impact on resurgence small modular reactors (SMRs). SMRs have been recurrently studied in past, from early days nuclear power, but never gained sufficient traction to reach commercialization. situation persisted also 1990s; focus was large based presumed common wisdom this being only way make power plants competitive. is one several reactor concepts that originated...
IRIS is an advanced integral pressurized water reactor, developed by international consortium led Westinghouse. The licensing process requires the execution of and separate effect tests on a properly scaled reactor simulator for concept, safety system verification, code assessment. Within framework Italian R&D program Nuclear Fission, managed ENEA supported Ministry Economic Development, SPES3 facility under design will be built operated at SIET laboratories. simulates primary,...
Recent pressure vessel fast fluence calculations have revealed numerical difficulties (spatial oscillations) in the SN solutions, which persisted spite of mesh refinement. It is demonstrated that other shielding/deep-penetration applications may be affected; fact, any solution uncollided flux component significant likely to exhibit such difficulties. Test problems been designed characterize and understand Main analyses are performed using diamond-difference (DD) scheme, linear forms basis...
Credibility requires predictability. Nuclear power plant (NPP) construction projects tend to be large and expensive, sometimes with high cost overruns far beyond those that might have been expected or predicted due usual recognized uncertainties variations (e.g., in labor materials costs combined multiyear duration complex logistics). This unaccounted for uncertainty brings the credibility of new NPP build into question may prevent future from going forward. It is believed initial capital...
The majority of nuclear reactors operating in the world today and similarly near-term new build will be LWRs. These currently accommodate traditional Zr clad UO2/PuO2 fuel designs which have an excellent performance record for normal operation. However, events at Fukushima culminated significant hydrogen production explosions, resulting from high temperature Zr/steam interaction following core uncovering extended period. resulted increased emphasis towards developing more accident tolerant...
One of the major limiting factors to nuclear reactors lifetime is radiation-induced material damage in Reactor Pressure Vessel (RPV). While older were designed assuming a 40-year operating lifetime, new reactor designs are expected have lifetimes up 100 years. For safe operation, integrity RPV must be ensured against significant property changes. In this work, typical neutron indicators calculated I2S-LWR (Integral Inherently Safe LWR) Power Plant, including DPA (displacements per atom) and...
