Some Technical Solutions for Environmental Protection System during Accidents at Nuclear Power Plants

[Occupational radiation exposures during maintenance activities at nuclear power plants].

Occupational exposures at nuclear power plants occur mostly during maintenance activities rather than during routine reactor operation. In this paper, statistical summaries of occupational exposures during routine maintenance activities for the years 1982-84 at nuclear power plants in Japan are presented, including comparison of the exposure levels by reactor type and by plant age. Average annu...

Alternative evacuation strategies for nuclear power accidents

In the U.S., current protective-action strategies to safeguard the public following a nuclear power accident have remained largely unchanged since their implementation in the early 1980s. In the past thirty years, new technologies have been introduced, allowing faster computations, better modeling of predicted radiological consequences, and improved accident mapping using geographic information...

Environmental Radiological Surveillance around Nuclear Power Plants in Argentina

During the last five years of operation of Atucha I Nuclear Power Plant (CNA I) and Embalse Nuclear Power Plant (CNE), a field team from the Environmental Radioactivity Division of Nuclear Regulatory Authority (NRA) has carried out surveillance programs in the surroundings of these facilities, in order to estimate the radiological impact. The argentine nuclear power plants use natural uranium a...

Mobile Post-Emergency Monitoring System for Nuclear Power Plants

In this paper, a concept of designing the post-emergency system for monitoring the equipment and territory of nuclear power plant after a severe accident was developed. Power and communications network lines are found out as the most vulnerable ones during the accident monitoring, and selfdescriptiveness and survivability and veracity are recognized as system basic parameters. To ensure the sel...
