EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 28 / 257 5. The licensee shall, if so specified by the Executive, not accumulate radioactive waste except in a place and in a manner approved by the Executive. This Licence Condition requires the licensee to make and implement adequate arrangements for minimising so far as is reasonably practicable the rate of production and total quantity of radioactive waste accumulated on the site at any time and for maintaining records of accumulated waste. The underlying purpose of the Licence Condition is to ensure that licensees have regard to the total quantities of waste that accumulate on a site and that where required the form of the waste is such that it is passively safe 1 . 3.4.2 Licence Condition 33 Disposal of Radioactive Waste Licence Condition 33 requires that: The licensee shall, if so directed by the Executive, ensure that radioactive waste accumulated or stored on the site is disposed of as the Executive may specify and in accordance with an authorisation granted under the Radioactive Substances Act 1960 (RSA 60) or, as the case may be, the Radioactive Substances Act 1993 (RSA 93; Ref. 10). The majority of Certificates of Authorisation are now granted under RSA93. Any New Nuclear Power Station will apply for an authorisation under RSA93. This Licence Condition provides the HSE with power to direct a licensee to dispose of waste. In practice this power is rarely used. 3.4.3 Licence Condition 34 Leakage and Escape of Radioactive Material and Radioactive Waste Licence Condition 34 states that: 1. The licensee shall ensure, so far as is reasonably practicable, that radioactive material and radioactive waste on the site is at all times adequately controlled or contained so that it cannot leak or otherwise escape from such control or containment. 2. Notwithstanding paragraph (1) of this condition the licensee shall ensure, so far as is reasonably practicable, that no such leak or escape of radioactive material or radioactive waste can occur without being detected, and that any such leak or escape is then notified, recorded, investigated and reported in accordance with arrangements made under condition 7. 3. Nothing in this condition shall apply to discharges or releases of radioactive waste in accordance with an approved operating rule or with disposal authorizations granted under RSA60 or, as the case may be, RSA93. 1 In the context of decommissioning and the interim storage of nuclear matter, providing and maintaining a safety function by minimising the need for active safety systems, monitoring or prompt human intervention.
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 29 / 257 This Licence Condition requires that the licensee shall ensure, so far as is reasonably practicable, that radioactive material and radioactive waste on the site is at all times adequately controlled or contained so that it cannot leak or otherwise escape from the containment and that in the event of any fault or accident which results in a leak or escape, there are adequate means for detecting the leak and reporting the incident to the HSE. 3.4.4 Safety Assessment Principles The NII provides guidance to its inspectors on the assessment of safety cases in their Safety Assessment Principles (SAPs) [Ref.11]. The SAPs relating to radioactive waste are as follows: · A strategy should be produced and implemented for the management of radioactive waste on a site (RW.1); · The generation of radioactive waste should be prevented or, where this is not reasonably practicable, minimised in terms of quantity and activity (RW.2); · The accumulation of radioactive waste should be minimised (RW.3); · Radioactive waste should be characterised and segregated to facilitate subsequent safe and effective management (RW.4); · Radioactive waste should be processed into a passively safe state as soon as is reasonably practicable (RW.6); · Radioactive waste should be stored in accordance with good engineering practice and in a passively safe condition (RW.5); · Information that might be required now and in the future for the safe management of radioactive waste should be recorded and preserved (RW.7). The SAPs also contain decommissioning principles. These reflect the regulatory expectation that decommissioning should be taken into account throughout all stages of the design and operation of nuclear plant. The decommissioning principles are as follows: · Facilities should be designed and operated so that they can be safely decommissioned (DC.1); · A decommissioning strategy should be prepared and maintained for each site and should be integrated with other relevant strategies (DC.2); · Decommissioning should be carried out as soon as is reasonably practicable taking relevant factors into account (DC.3); · A decommissioning plan and programme should be prepared and maintained for each nuclear facility throughout its lifecycle to demonstrate that it can be safely decommissioned (DC.4); · The facility should be made passively safe before entering a care and maintenance phase (DC.5) 2 ; 2 BERR guidance indicates that immediate decommissioning is preferred. The EPR reactor can be decommissioned over a period of twelve years immediately following shutdown with an assumed 40- year safe interim storage of packaged wastes. Each utility will develop their own decommissioning programme.
