Tribocorrosion in Pressurized Water Reactors

2013
Most of the metallic alloys employed in pressurized water reactors (PWRs) have passivating properties that allow them to withstand relatively aggressive environmental conditions such as high temperatures, high pressure, and water-based coolants containing boric acid and lithium hydroxide.

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.

Dynamic analysis of a pressurized water reactor

Annals of Nuclear Energy, 1976
Abstract An apparent malfunction in a pressurized water reactor system has been investigated using fluctuation analysis. Both frequency-domain and time-domain analyses have been used and the results obtained by the two methods have been compared. The recording was performed by a relatively simple, cheap system giving high recording precision and the ...

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 ...

Constrained control for a pressurized water reactor

Proceedings of the 37th IEEE Conference on Decision and Control (Cat. No.98CH36171), 2002
One of the main objective in controlling a pressurized water reactor of a nuclear power plant is to regulate the temperature of the water of the primary circuit while satisfying many constraints on both input and measured variables. We describe two approaches to deal with such constraints. The first approach is a classical 2-step design procedure where

High Pressure Boiling Water Reactor

Nuclear Technology, 2010
Some 400 boiling water reactors (BWRs) and pressurized water reactors (PWRs) have been in operation for several decades. The presented concept, the high pressure boiling water reactor (HP-BWR), combines the best parts and omits the troublesome components of traditional BWRs and PWRs by taking into consideration the experiences gained during their ...

The reliability of pressurized water reactor vessels

1987
The mechanical integrity of major engineering structures such as pressure vessels, pipelines, nuclear reactors, aircraft and offshore oil platforms is a matter of great practical importance for both economic and safety reasons. In practice this integrity must be assured by careful attention to many aspects of design, materials, manufacture, inspection,
