Preventing recurrence of severe accidents at nuclear power plants

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...

Comparison of the Chernobyl and Fukushima Nuclear Power Plants Accidents and their Consequences

This work compares the radioactive consequences due to the Chernobyl and Fukushima NPP accidents. Due to non-homogeneous features of the fallouts of radioactive isotopes in the both cases the comparison of radioactive contamination density was compared for similar administrative units – in Russia (Bryansk region, Novozibkov subregion) and in Japan (Fukushima prefecture, Namie municipality). We ...

Accidents in a nuclear power reactor operation.

Automations influence on nuclear power plants: a look at three accidents and how automation played a role.

Nuclear power is one of the ways that we can design an efficient sustainable future. Automation is the primary system used to assist operators in the task of monitoring and controlling nuclear power plants (NPP). Automation performs tasks such as assessing the status of the plant's operations as well as making real time life critical situational specific decisions. While the advantages and disa...

[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...
