Leiston Development and Sizewell Emergency Arrangements

Information released

Q1) Could you please explain why the assessment of Sizewell B RoA / HIRE has not been completed. The station has been operating since 1995. Does the failure to have completed these assessments imply that the Emergency Arrangements have not been adopted to meet the requirements of the B Station?

A1) Sizewell B produced an RoA / HIRE in 2001 and the station has submitted triennial declarations of no change since then, in accordance with the requirements of REPPIR.  There has been no failure to complete the required assessments by the licensee. 

Q2) I now refer to your last sentence of section 2. "After receipt .of further information from SCC.."  Would you please supply, under the FoI Act, a copy of this further information?

A2) I have attached a pdf copy of email correspondence between ONR and Suffolk County Council that contains the further information received from SCC and the ONR response to it.  Personal details names, etc have been redacted under Reg 13 - which is an absolute exemption not requiring a Public Information Test.

Q3) The NII and SCDC told the Sizewell B Inquiry that only another 157 domestic units would be built in Leiston. As a FoI request would you please confirm when this policy was abandoned, how were the public informed of the change of policy, what was the technical basis for this change of policy?

A3) The ONR's policy on Land Use Planning may be summarised as follows. 

When consulted on planning applications ONR will state that it does not advise against the proposed development on planning grounds if, in the Inspectors opinion, both of the following statements apply:

  1. local authority emergency planners have provided adequate assurance that the proposed development can be accommodated within their existing off-site emergency planning arrangements (or an amended version); and
  2. the development does not represent an external hazard to a nuclear licensed site  

These conditions reflect ONR's regulatory functions with regard to:

  1. the Radiation (Emergency Preparedness and Public Information) Regulations 2001 (specifically the requirement for the relevant local authority to prepare an adequate off-site emergency plan if it is reasonably foreseeable that a radiation emergency may arise on a nuclear site); and
  2. the ONR's nuclear health and safety purposes, including: securing the health, safety and welfare of persons at work on GB nuclear sites; and protecting persons, other than persons at work on GB nuclear sites, against risks to health or safety arising out of or in connection with the activities of persons at work on GB nuclear sites; Policy is not determined nor defined by evidence presented in Public Inquiries.
