• 123rd session of the Steering Committee for Nuclear Energy on 27-28 October.
• Fukushima-related activities and NEA work in a policy debate
• Official request received from the Russian Federation on 24 October to join the NEA (fact-finding mission)
• Approved NEA co-sponsorship of the new "Radiation Protection and Safety of Radiation Sources: International Basic Safety Standards", as adopted by the IAEA Board of Governors in September 2011.
ISOE EG-SAM • collecting information on dose management of high radiation area workers and practical experience available in the
nuclear industry on addressing operational aspects, dosimetry, etc with special emphasis on procedures to the control of occupational exposures,
• Some first elements have been identified for collecting information, such as : – RP Management on an highly contaminated / irradiated area – RP equipment needed on site – Emergency procedures dosimetry prevision (the post accident situation "normal" procedures) – Remote tooling available – Sites stress tests dosimetric impact – Crew stress management – Searching and stopping of releases and contamination carry off – Means to fix and eliminate contamination, – Access procedures to the site, – Monitoring of high dose rate areas, pinpoint hot spots – Shielding and blocking of high dose rate areas – Declaration of new controlled areas and zoning – Selection of persons to act in emergency organizations and be exposed above normal annual dose limit (e.g.
genetic tests)
• identifying factors and aspects which play key roles in achieving good practices on occupational radiation protection in severe accident management and post-accident recovery (knowledge, experience, technology, regulatory requirements and guidance, worker involvement, information exchange, training aspects, etc) and analysing and quantifying their impact on worker doses,
• submitting a report, including possible recommendations for further work, to the ISOE MB for approval, and to the CRPPH.
– Management of multiple risk situations (radiation risk and conventional workplace risks, e.g. chemical hazards, heat stress, etc.) and the role of RP professionals,
– Management of occupational radiation risk in the context of nuclear safety, environmental safety, industrial safety and facility reliability.
– Comparison of existing radiation passbook systems in OECD countries in order to reflect need and appropriate extent of an international harmonisation,
– Implications of different national dose limits in origin and destination countries of transboundary travelling nuclear workers,
– Provisions for dose recording of trans-boundary itinerant workers for complete individual dose histories.
A worker from another country intents to work temporarily in your country in a radiation controlled area (e.g. in a nuclear power plant during a periodical revision).
What sort of dose (exposure) data does your regulatory authority require in
order to allow the worker to access a controlled area? Please identify in terms of:
– Data about previous / current-year estimated doses to the worker as recorded by operational dosimetry (for example, electronic dosimetry or direct-reading dosimeters,
sometimes documented in a radiation passbook carried by the worker),
– Data about previous / current-year doses of the worker from official “dose-of-record” dosimetry (usually data base extracts from accredited dosimetry services or central
• From whom is this dose information for the itinerant worker requested? (worker, licensee, others?)
• Is verification of the information carried by an arriving worker required to be sought or received prior to the worker’s accessing a controlled area?
• What other information does the regulatory authority of your country require from an itinerant worker from another country in order for the worker to be allowed to access a controlled area (e.g., medical record which indicates the physical condition of the worker as medically fit/conditionally/not fit, radiation protection training, and/or respiratory protection training)?
• Do the dose limits in your country that are applied to an itinerant
worker refer to a:
calendar year?
twelve-month exposure period beginning in another month of
the calendar year,
rolling twelve-month period?
Your country and the applicant’s home country may have differently specified dose limits (e.g., 20 mSv/year vs. 50 mSv/year, calendar year vs. rolling 12 month period, etc.).
EGBAT Workshop • The workshop will focus on achieving a broad understanding of the practical aspects
of effluent management regulation and application, with a view to support the EGBAT in improving its draft document to also represent “best practice”.
• The overall objective of the workshop will be to identify those optimisation and BAT effluent management aspects on which there is agreement, and on which there still remain questions for example:
– What are the aspects of effluent management that characterise good practice?
– Building a bridge between good operating practice for Gen 3 to New Build
– What aspects of monitoring and reporting could use some form of harmonisation, and why?
– If you had no constraints to improving your system, what would you change? What priority would you identify to selecting from such a list of possible improvements?
