ONR represents the UK at the IAEA Transport Safety Standards Committee (TRANSSC) and is seeking views on other Member State proposals concerning SSG-26. ONR will hold a Stakeholder meeting at its Bootle office on 2 October 2018 but spaces are limited. If you think that you need to attend then please email firstname.lastname@example.org. If you are unable to attend the meeting but you have comments on either the latest draft of SSG-26 or the current Member State proposals then please email those comments to email@example.com clearly marked SSG-26 review; and we will make sure that your comments are noted at the meeting. Member State comments have been through an initial review at an IAEA Consultants meeting. We expect that proposals will receive final sentencing at the next TRANSSC, which is planned for 26 to 30 November 2018.
This is a continuation of the consultation on DS496 that ONR initiated in September 2017.
ONR's mission is to provide efficient and effective regulation of the nuclear industry, holding it to account on behalf of the public. ONR Transport's contribution to achieving the mission is to regulate safety and security during the transport of radioactive material by road and rail in Great Britain. ONR Transport also advises on the transportation of radioactive material by air and sea within the United Kingdom's territorial waters. This includes the movement of flasks carrying spent nuclear fuel from operating and decommissioning nuclear reactors, radio-pharmaceuticals needed for hospitals, sealed radioactive sources needed in the construction industry and, for instance, in the non-destructive testing of North Sea oil rigs.
ONR Transport carries out a range of regulatory activities to assure the safe transport of radioactive materials. Approval is granted for the designs of packages used to carry high-hazard radioactive materials to ensure they meet exacting international safety standards, and the packages are built to robust quality assurance plans, and are correctly used and maintained. Regulation is also carried out through a programme of targeted, risk-informed inspections and engagement with duty holders which may lead to interventions. Inspections examine the management systems utilised by duty holders, as well as compliance with safety and security legal requirements. ONR Transport inspects duty holders across nuclear; non-nuclear; and industrial, medical and carrier sectors.
Regulations governing the transport of radioactive material in Great Britain are based on standards developed by the International Atomic Energy Agency. The IAEA regulations are prescriptive and apply internationally to enable the safe transport of packages across international borders.
For more information see guidance and resources.
For advice and guidance on the transport of dangerous goods you should first consult a Dangerous Goods Safety Adviser (DGSA .
For specific advice regarding the transport of radioactive materials you should consult a Radiation Protection Adviser (RPA) .
If you have been unable to get the advice or guidance you seek regarding the transport of radioactive materials from your DGSA or RPA you may wish to contact ONR at firstname.lastname@example.org.
Organisations who transport radioactive substances have a duty to notify ONR of incidents or other events that have the potential to affect safety or security. The following guidance explains when and how to notify ONR:
|Between 08.30 and 17.00 (Monday to Friday)||0151 922 5911|
|Out of hours||0151 922 9235|
According to paragraphs 673(a)(vi) and 679 of the IAEA Transport Regulations, SSR-6, and paragraph 673.8 of the IAEA Transport Guidance, SSG-26, temperatures resulting from ambient conditions of –40°C to +38°C should be considered unless the Competent Authority specifies otherwise in the certificate of approval. Package temperatures resulting from the thermal tests should also be considered.
Temperature variations in a transport package will result in changes in both the physical and nuclear properties of the package materials. Until very recently, it has not been practicable to assess the effects of temperature on the criticality safety of transport packages. Preliminary studies using the latest nuclear data library JEFF3.1.2, which has only recently become available to the industry, indicate that temperature variations may lead to a change in neutron multiplication.
The IAEA Transport Regulations require the impact of temperature on criticality safety to be assessed. Applicants for a transport licence must consider both the nuclear and physical effects of temperature changes (eg reactivity changes from contraction/expansion).
Suitable methods to estimate the impact on criticality safety of low temperatures should be used, for example considerations based on nuclear and physical data and/or suitable extrapolations from data obtained at higher temperatures and supported by reasoned arguments. For those packages with a large criticality safety margin being transported solely in the UK, reasoned argument may be sufficient.
For existing package approvals, the evidence so far does not indicate that temperature variations will compromise criticality safety. ONR is currently discussing this issue with a number of international competent authorities, and establishing research needs in this area.
ONR encourages early engagement in order to discuss package approval applications on a case by case basis; for some applications a temperature restriction or a Special Arrangement may be appropriate. ONR will take a proportionate approach in assessing applications.
The International Atomic Energy Agency (IAEA) commenced a review and revision cycle in 2015 for the regulations and advisory material concerning the transport of radioactive material. Following notification from the IAEA (Note Verbale) and in consultation with the GB Stakeholders, we put forward the following UK proposals and formed a GB position on each of the other Member State’s proposals. We also produced a position paper on two specific proposals that seek to change IAEA SSR-6  with respect to dose rate allowable increases following Normal Conditions of Transport
In November 2015, TRANSCC 31 decided that there were a sufficient number of significant changes required to revise SSR-6 and they tasked a consultancy group to produce a working draft SSR-6. Based on this draft, we have produced a presentation which briefly describes each of the main changes to SSR-6.
The working draft of SSR-6 will be discussed by TRANSSC 32 in June 2016, after which Member States will have a further 120 days to provide any final comments
This draft document, is the proposed revision of SSR-6 and has been sent to Member States for final review. This is not to seek further proposals for changes but instead to check that the implementation of the agreed changes is correct.
The Office for Nuclear Regulation (ONR) is responsible for regulating the transport of radioactive materials to and from the nuclear licensed sites in the UK. ONR is also responsible for regulating the transport of radioactive materials used by organisations in the industrial and medical sectors (for example; hospital trusts, universities, laboratories etc).
We are currently requesting information from organisations within the industrial and medical sectors that transport radioactive material. The information gathered will be used to inform our inspection programme and to ensure that a risk based approach is used for the regulation of radioactive material transport.
On 1st April 2014 ONR Transport introduced cost recovery for all package design approvals. Prior to the decision to adopt the cost recovery scheme, ONR carried out an Impact Assessment which took into account comments from industry and ONR's other stakeholders. A guidance document explains how cost recovery works across ONR's programmes.
This Authorisation (No.500) will exclude from CDG the transport of certain very low level radioactive wastes that are permitted to be disposed of as normal waste to public landfill.1 Essentially this means that organisations like schools and universities that are allowed to dispose of very small quantities of radioactivity by this route, may now use normal refuse collection services to do so, subject to conditions in the authorisation.
ONR’s technical assessment supporting this work concludes that there will be no resulting impact on public safety from the introduction of the authorisation.2
ONR has issued an Authorisation (501) under Regulation 12 of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (as amended) (CDG)
This Authorisation (No.501) will permit the transport of certain types of Class 7 goods where asbestos forms a subsidiary hazard and the conditions of ADR or RID Special Provision 168 cannot be met. Essentially this means that some types of radioactive material comingled with asbestos may be transported in an IP-2 or Type A package after wrapping in polythene subject to conditions in the authorisation.
ONR has issued an Authorisation (502) under Regulation 12 of the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2009 (as amended) (CDG)
This Authorisation permits the use of a Regular Transport Document within Great Britain, subject to certain conditions in the authorisation. Essentially this allows the same transport document to be used for a specified period of up to 3 months, where the same packaging with the same radioactive contents (and no sub-risk) is consigned on a regular basis in GB by the same consignor, who is also the carrier of that package.
