The Pebble-Bed Modular Reactor: Safety Issues

The Bush Administration has made the expansion of nuclear power generation a centerpiece of its domestic energy policy. However, the White House has not addressed the practical issue of how to overcome the nearly three-decade-long aversion among U.S. electric utilities to investing in new nuclear plants. In today's deregulating market, utilities will not build new nuclear power plants unless th...

Safety Aspects of Nuclear Reactor Control

Reactor control and safety systems are discussed with emphasis on safety considerations. Consideration is given to the importance of reactor characteristics, control and safety system characteristics, the operational program of the reactor, and credible accidents, in a determination of safety of operation. Ecperience with research reactor control and safety systems has led to the development of...

Assessment of Cfd Codes Used in Nuclear Reactor Safety Simulations

The spectacular growth in computer hardware over the last quarter century and the accompanying advances in software development have resulted in the availability of reliable numerical tools for addressing safety issues in Nuclear Power Plants (NPPs). The first step forward was undertaken in the 1970s with the development of system codes using the two-fluid model approach [1], such as RELAP-5 [2...

Safety Status of Space Radioisotope and Reactor Power Sources

The current overall safety criterion for both radioisotope and reactor power sources is containment or immobilization in the case of a reentry accident. In addition, reactors are to be designed to remain subcritical under conditions of land impact or water immersion. A very extensive safety test and analysis program was completed on the radioisotope thermoelectric generators (RTGs) in use on th...
