Comprehensive exergetic and economic comparison of PWR and hybrid fossil fuel-PWR power plants

Energy, 2010
A typical 1000 MW Pressurized Water Reactor (PWR) nuclear power plant and two similar hybrid 1000 MW PWR plants operate with natural gas and coal fired fossil fuel superheater-economizers (Hybrid PWR-Fossil fuel plants) are compared exergetically and economically. Comparison is performed based on energetic and economic features of three systems.

Surveillance of vibrations in PWR

Progress in Nuclear Energy, 1982
Abstract The core of a PWR — including fuel elements, internal structure, control rods and core support structure inside the pressure vessel — is subjected to forces which can cause vibrations. One sensitive method to detect and analyse such vibrations is by means of the noise from incore and excore neutron detector signals.

Simulation of PWR Crud

Volume 1: Plant Operations, Maintenance, Engineering, Modifications, Life Cycle and Balance of Plant; Nuclear Fuel and Materials; Plant Systems, Structures and Components; Codes, Standards, Licensing and Regulatory Issues, 2014
Corrosion products deposit on Pressurized Water Reactor (PWR) fuel rod cladding surfaces and can create a number of issues including increased cladding temperature, elevated cladding corrosion, and the precipitation of boron species within the deposits.

PWR pressurizer modeling

Nuclear Engineering and Design, 1987
Abstract A series of experiments have been performed which help to provide fundamental understanding of the phenomena which are important to the analysis of a PWR pressurizer. The transients considered include insurges to a partially-full tank, outsurges, insurges to a tank with hot walls, empty tank insurges, and combined insurges and outsurges. The

Construction time of PWRs

Energy Policy, 2013
Abstract The construction time of PWRs is studied considering published data about nuclear power plants in the world. For the 268 PWRs in operation in 2010, the mode of the construction time distribution is around 5–6 years, and 80% of the plants were built in less than 120 months.

A Small PWR-Core Physical Calculation Based on PWR-Core Analysis Code CORAL

Volume 3: Computational Fluid Dynamics (CFD); Verification and Validation; Advanced Methods of Manufacturing (AMM) for Nuclear Reactors and Components; Decontamination, Decommissioning, and Radioactive Waste Management; Beyond Design Basis and Nuclear Safety; Risk Informed Management and Regulation, 2021
Abstract Three dimensional PWR-core analysis code CORAL is developed by Wuhan Second Ship Design and Research Institute. This code provides basic functions including three-dimensional power distribution, fine power reconstruction, fuel temperature distribution, critical search, control rod worth, reactivity coefficients, burnup and ...

Scaling of natural circulation in PWR systems

Nuclear Engineering and Design, 1991
Abstract This paper deals with the problem of scaling complex thermalhydraulic scenarios measured in experimental facilities which simulate Pressurized Water Reactor systems. Phenomena occurring during different phases of natural circulation between the core and the steam generators are considered. The experimental data obtained in some integral test
