PERFORMANCE OPTIMISATION

The main areas that contribute to nuclear plant availability and reliability have been investigated in an IAEA study of six representative plants (IAEA-TECDOC-1098, 1999; Table 4.3). This involved case studies of plants from Western and Eastern Europe and the US. The plants chosen for the study had exhibited high-energy availability factors and also improvements over recent years in safety, availability […]

ACTIVE HEAT REMOVAL SYSTEMS

The dissipation of decay heat is accomplished in present generation water reactors via redundant and diverse emergency core cooling systems (ECCS). One approach in evolutionary reactor development, both ALWRs and AHWRs, is to utilise the best features of these present systems in an optimal way (Yadigaroglu et al., 1998), without significant recourse to new passive systems. Reactors based on this […]

Lead Cooled

12.6.2.1 BREST-300. Lead cooled reactor systems are under study at the Institute of Physics and Power Engineering (IPPE) and the Kurchatov Institute (IAEA-TEC- DOC-1289, 2002). In the BREST-300 designs, developed by RDIPE and Kurchatov there is a two circuit design, there are four parallel loops including pumped lead flow removing heat from the reactor core. Lead inlet and outlet temperatures […]

RUTA-TE

A number of small medium-size nuclear power plants have been developed by RDIPE in Russia for district heating which can also be used for seawater desalination. RUTA-TE is a pool-type thermal reactor that can be used for the cogeneration of electricity and power. The RUTA concept has already been described earlier in the book and more details are given in […]

In-Vessel

The main areas for additional research on in-vessel related response, following a core melt event, relate to the timing and influence of reflood, both early and late (Krugmann, 2001). There are uncertainties in the late core degradation mechanisms and how these affect the pressure vessel failure mode. There have been experimental programmes at Sandia

The Future of Nuclear Power

J. N. Lillington During the last century, nuclear power has been established as a reliable source of energy in the major industrialised countries. It has a potentially important role in the future since it does not contribute to the production of ‘Greenhouse’ gases; a growing concern of continued fossil fuel power generation. The time is now appropriate to review the […]

Operational Safety

3.1. INTRODUCTION/OBJECTIVES This chapter addresses the issues of operational safety for existing nuclear power plants. It concerns safety throughout all aspects of power plant operation and a number of topics are covered. There are diverse issues, some of which have already been introduced in the previous chapter. The management of radioactive waste is a particular concern and must be resolved, […]
