Severe Accident Management Systems and Procedures

A nuclear power plant’s safe operation involves the planning for non-standard operational emergencies, where pre-determined safety measures and damage control interventions must be taken into consideration depending on the developed event. A nuclear power plant’s safe operation involves the planning for non-standard operational emergencies, where pre-determined safety measures and damage control interventions must be taken into consideration depending on the developed event. The definition of the severe accident management cannot be explained in a single concept, it needs to be examined in detail. As a result of this it becomes necessary to specify the procedure guidelines appropriate to the nature of the event, which can be used with optimal efficiency under hierarchical organisational control. The experience of nuclear accidents in the world and the precognition of future events, the knowledge of existing guidelines for severe accident management needs to be deepened continuously, but at the same time it can be parallelly upgraded with the application of new technologies.

The Identification of Characteristic, Cause, and Disaster Management of Traffic Accident at the Sungailiat – Belinyu Road

This study aims to identify the characteristic, cause, and disaster management of traffic accidents at the Sungailiat – Belinyu road. The research method used is descriptive quantitative. Data collection techniques is in the form of documentation and observation. The data collected then analyzed using data analysis techniques with classification methods. Based on the research done, the results obtained are the accidents that occur on Jalan Raya Sungailiat - Belinyu are the most common in Riau Silip District with a percentage of 59.8%. The accidents characteristics on Sungailiat - Belinyu road based on the time of the incident, mostly occurred during the afternoon to evening at 12.00 - 17.59 WIB and in the evening at 18.00 - 23.59 WIB. Based on the type of collision, the most common types of collisions are frontal collisions by 30% and collisions due to loss of control by 26.6%. Based on road users, road users who are most involved in accidents are motorcycles by 40%, cars by 23.3%, dump trucks by 10%, and the other vehicles in a small percentage. As for the factors causing the accident, it was found that the accident was caused by road users (73.33%), road factors (23.33%), and environmental factors (6.66%). The handling of accident management is arranged according to the causative factors that are done before, when it occurs, and after an accident occurs as an effort to reduce the risk of accidents on the Sungailiat – Belinyu road, Bangka Regency.

Supporting societal and economic dynamics of recovery: lessons from Chernobyl and Fukushima

This paper does not necessarily reflect the views of the International Commission on Radiological Protection. Beyond the consideration of radiological aspects, the rehabilitation of living and working conditions after a large nuclear accident is a complex process in which all dimensions of individual and community life are involved and interconnected. Responsibles of socio-economic entities are facing various difficulties/challenges, including the implementation of protective actions for ensuring the protection of employees, the continuity of production of good-quality products in affected areas, and restoring the confidence of consumers. For affected local communities, the deployment of a socio-economic programme is essential to enable a sustainable future while recognising that a return to the pre-accident situation is generally not achievable. In this context, supporting the societal and economic dynamics of the recovery process requires the adoption of specific governance mechanisms respecting a series of ethical and social values, as highlighted by lessons from the post-accident management of the Chernobyl and Fukshima accidents at Chernobyl and Fukushima Daiichi nuclear power plants.

Involvement of stakeholders during the preparedness phase of post-accident situation management

The Steering Committee for Post-accident Management Preparedness (CODIRPA) was commissioned by the French Government in 2005 with the aim of establishing the main principles to be set up for population protection and recovery in the long term. From the beginning, one of the main principles was the pluralistic nature of the working groups (WGs), including scientific and technical experts, representatives from state departments, nuclear operators, and representatives of civil society (i.e. stakeholders). Stakeholders were mainly associated with the various WGs of CODIRPA. In order to foster the involvement of stakeholders from civil society in the works of CODIRPA, a new organisation was implemented with two WGs: one mainly composed of technical experts for tackling technical issues, and one for evaluating the proposals made by the experts from the stakeholders’ point of view. This article presents the results of this new strategy.

Development and usage of the digital SAMG system

In order to reduce the work burden during the training and drilling of the severe accident and severe accident management guidelines, and improve the implementation efficiency of the guidelines, a method of digitizing the SAMG program files is proposed. A set of digital SAMG system supported by information technology and combined with software and hardware is developed to transform the manual processes of paper file browsing, data searching, logical judgment and auxiliary calculation into automatic and digital processes, which can be used for SAMG training and drilling, and also for verifying the SAMG execution process and the effectiveness of mitigation measures.
