EGIRES – Survey on National Experiences


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.


CRPPH Expert Group on Occupational Exposure (EGOE)

– Scope: Policy and strategic areas of ORP in the OECD countries with a focus on the nuclear power sector,

– since 2006,

– 30 members, observers and consultants from 13 OECD countries

and International Organisations.


Work of the EGOE

Policy and strategic areas of ORP,

with a focus on the nuclear power sector

• Case Study No.1: ORP principles and criteria for designing new NPPs (Published in 2010)

• Case Study No.2: Dose Constraints in ORP – Regulations and Practices - approved by the CRRPH for publication (May 2011) (Published in 2011)

• Case Study No.3: Radiological protection policy and operational issues

• Management of total risk

• Trans-boundary itinerant workers


Case Study 1

12

Occupational radiation protection

principles and criteria for

designing new nuclear power

plants

From “a posterior” to “a priory”.

Integrating occupational radiation

protection principles already at the design

stage of nuclear power plants.


Case Study 2

13

Dose Constraints in Optimisation

of Occupational Radiation

Protection

in the light of

• the concept of ICRP Pub. 103,

• international and national regulations,

• operators’ practices and experiences in

NPP and non-nuclear sectors.


Case Study 3

Management of total risk

– 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.

14


Case Study 3

Trans-boundary Itinerant Workers

Background:

– 90 % of all NPPs are situated in OECD countries

– Increasing international exchange of nuclear outside workers

between these countries,

– RP Issue for itinerant workers on the agendas of the European

Union and the IAEA,

– Important: a timely and co-ordinated approach by the relevant

international organisations.

15


Trans-boundary itinerant workers (cont.)

Analyses of the following items:

– 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.

16


Survey on trans-boundary itinerant Workers

– Questionnaire for CRPPH Members

– Sent out by e-mail through CRPPH Bureau (15. Nov. 2011)

– Response expected until 01. Dec. 2011

17


Questionnaire

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

dose registers),

– Other dose (exposure) data.

18


Questionnaire (cont.)

• 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)?

19



• 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.).

What annual dose limits apply to the applicant?

20



A radiation worker from your country worked and received occupational dose in

another country and returns back to your country.

Does your country register the occupational exposure doses of the worker

received in another country?

– If yes, how do you collect estimated dose and official dose-of-record

information?

– How do you provide data to other countries on occupational exposure accrued in your country?

– Do you have any restrictions on privacy regarding dose and medical records?

• 11th EGOE meeting: (30/31 Jan.2012)

• Progress report to the CRPPH (20. March 2012)

• 12th EGOE meeting (Autumn 2012)

publication to CRPPH (Spring 2013)

EGOE plans for 2012 / 2013


Effluent Management

• Assessment report on BAT for new build

– Good Practice in Effluent Management for Nuclear

Power Plant New Build

• Comparison of discharge data for potential new build reactors.

• Discussion of discharge data with stakeholders e.g. reactor operators and vendors.

• Organisation of a workshop on BAT with regulators, operators and vendors.

• Preparation of guidance on BAT, potentially with input into the MDEP.

• Workshop on Effluent Management (24 – 26 January 2012)


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?
