Comprehensive exergetic and economic comparison of PWR and hybrid fossil fuel-PWR power plants
Energy, 2010A 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.

The control of a nuclear power plant is important due to its nonlinear dynamics. An optimized proportional–integral–derivative (PID) controller is a popular tool to this end. PID is tuned by various methods, including a genetic algorithm (GA).

The objective of this work is to determine which of the main three fuel types (UO2, (Th,U)O2 and MOX fuel) can burn minor actinides (MAs) effectively and at the same time sustain the main operating parameters at an acceptable level.

Surveillance of vibrations in PWR
Progress in Nuclear Energy, 1982Abstract 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.
