Stability analysis and parametric study of natural circulation integrated self-pressurized water reactor

, 2020
The stability analysis of a natural circulation integrated self-pressurized water reactor is investigated by the Lyapunov approach. The analysis of the pressurized water reactors (PWRs), particularly the integrated self-pressurized water reactors, is ...

Supercritical-Pressure Water Nuclear Reactors

Atomic Energy, 2004
The concepts concerning a nuclear reactor cooled by water at supercritical pressure (25 MPa) are presented. The system has one loop. Superheating the coolant to 530°C makes it possible to obtain ~44% efficiency. On the basis of the neutron spectrum, the reactor is a fast resonance reactor.

NOISE INVESTIGATIONS IN BOILING-WATER AND PRESSURIZED-WATER REACTORS

Progress in Nuclear Energy, 1980
Publisher Summary Reactor noise investigations, similarly to other scientific topics of engineering interest, can be divided into two categories: (1) the experimental and theoretical study of the phenomena, that is, the investigation of the information content of the different noise signals, and (2) the direct application of the technique aimed at ...

Development of an improved non-equilibrium multi-region model for pressurized water reactor pressurizer

Annals of Nuclear Energy, 2019
This paper presents an improved non-equilibrium multi-region model for accurate prediction of pressure in the pressurizer of pressurized water reactor under transient conditions. The pressurizer model consists of three layers: a liquid layer, a saturated
