Each Member State has its own system or network which usually covers its whole territory. makes radiological monitoring data from most European countries available on a routine daily basis – and in close to real-time in emergencies. To achieve this, EU Member States, and other European countries which are members of , send their data to on a daily basis from at least one territorial radiation-monitoring network (some countries have more than one). The system makes this radiological data available via a web page.

Q

As the Chernobyl emergency demonstrated, the release of radioactive materials into the atmosphere is a transnational issue. Winds will carry these materials into the atmosphere where they can disperse across borders and continents. The national monitoring systems linked through EURDEP can detect and track the movement of radioactive releases – but national systems differ in the atmospheric dispersion models they employ and the resulting forecasts. The platform ensures a common coherent strategy across European national emergency management efforts. It makes use of new decision-making procedures and web-based tools for real-time reconciliation and harmonisation of forecasts from meteorological and emergency centres across Europe during an accident.

A

The prime responsibility for the nuclear safety of a nuclear installation rests with the licence holder. That responsibility cannot be delegated and includes responsibility for the activities of contractors and sub-contractors whose activities might affect the nuclear safety of a nuclear installation.

Defence-in-Depth is a nuclear safety concept relating to the designing and operating of nuclear facilities that aims to prevent and mitigate accidents. The key is creating multiple independent and redundant layers of defence. This means that the safety and security system in place should be able to compensate for potential human and mechanical failures so that no single layer, no matter how robust, is exclusively relied upon. Defence-in-depth includes the use of stringent access controls, physical barriers, redundant and diverse key safety functions, and effective emergency response measures.

The Convention on Nuclear Safety does not contain provisions. The convention is an incentive instrument based on a common interest to achieve higher levels of safety. It obliges the parties to submit reports on the implementation of their obligations for and, if necessary, .

A

The Convention on Nuclear Safety does not contain verification provisions. The convention is an incentive instrument based on a common interest to achieve higher levels of safety. It obliges the parties to submit reports on the implementation of their obligations for review by other parties and, if necessary, clarification.

Q

The guiding principle of radiation safety is “, which stands for “.”

means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: , , and .

A

The guiding principle of radiation safety is “ALARA, which stands for “as low as reasonably achievable.”

ALARA means avoiding exposure to radiation that does not have a direct benefit to you, even if the dose is small. To do this, you can use three basic protective measures in radiation safety: time, distance, and shielding.

51
Q

What is the standardized approach to rating the severity of nuclear incidents and accidents?

A

The International Nuclear and Radiological Event Scale (INES)

52
Q

In the INES, events are rated at x levels. The scale is – that is, the severity of an event is about x times greater for each increase in level of the scale.
Events are considered in terms of:
* Impact on and the
* Impact on barriers and
* Impact on in depth
Events without safety significance are rated as Below Scale/Level .
Events that have no safety relevance with respect to radiation or nuclear safety are not rated on the scale.

A

In the INES, events are rated at seven levels. The scale is logarithmic – that is, the severity of an event is about ten times greater for each increase in level of the scale.
Events are considered in terms of:
* Impact on people and the environment
* Impact on radiological barriers and control
* Impact on defence in depth
Events without safety significance are rated as Below Scale/Level 0.
Events that have no safety relevance with respect to radiation or nuclear safety are not rated on the scale.
