Correlation between grain boundary strength determined by impact test of miniature specimen and stress corrosion cracking resistance of irradiated austenitic steels used for the internals of WWER-type and PWR-type nuclear reactors

Engineering Failure Analysis, 2021
Abstract Austenitic chromium-nickel 321, 316 and 304 stainless steels used for internals of PWR (pressurized water reactor) and WWER (water-water energetic reactor) reactors were irradiated to 4–125 dpa in different neutron energy spectra and investigated by impact bending tests of miniature specimens.

Considerations in the control of PWR-type multimodular reactor plants

IEEE Transactions on Nuclear Science, 1994
Issues in the control of PWR-type multimodular reactor plants are discussed with emphasis on the need for operation under conditions of unbalanced loads, operating strategies for both single- and multireactor systems, and the coordinated adjustment of power and temperature.

An Adaptive Gain Scheduled PID Controller for PWR type of Nuclear Reactor

2017 International Conference on Innovations in Control, Communication and Information Systems (ICICCI), 2017
In this paper a strategy for an adaptive gain scheduled PID controller is proposed for PWR type of Nuclear reactor. Nuclear reactors are highly nonlinear in nature. The proportion of Pressurized Water Reactor is beyond 60% of the total Nuclear reactor components, since PWRs are the most desirable reactors for producing nuclear power.

Numerical Investigation of Flow Diffuser Optimization for a PWR Reactor With Code_Saturne: Analysis on EPR Type Reactor

Volume 3: Thermal-Hydraulics, 2016
In order to provide scientific basis for new reactor design in terms of optimal Flow Diffuser, a study was launched on the analysis and investigation on flow distribution of existing flow diffuser design of five different reactors including EPR, VVER, Konvoi, APR+ and Westinghouse. The strategy is to change each time only the flow diffuser within the 1/
