Part 14: Civil Nuclear Sector Chapter 1: Civil Nuclear Sites Section 303: Decommissioning of nuclear sites etc
Section 303 amends provisions of the Nuclear Installations Act 1965 which concern nuclear third party liability and the processes for revoking and varying a nuclear site licence.
	It confirms that a nuclear site licence is required for decommissioning.
	Section 303 changes the conditions that must be satisfied before a nuclear site licence can be varied to exclude part of a site from that licence. The new conditions vary depending on the former use of that part of the site. The section also requires the appropriate national authority to consult the relevant Health and Safety Executive before revoking a nuclear site licence and removes a nuclear site licence holder’s ability to unilaterally surrender their licence. Licence holders will still be able to request that the appropriate national authority revoke or vary their licence.
	Section 303 also changes the conditions that must be satisfied in order to end the period of responsibility in respect of part of a nuclear licence site. The new conditions are based on the risk posed by the relevant part of the site. Where relevant, these amendments implement the OECD Nuclear Energy Agency’s 2014 "Decision and Recommendation of the Steering Committee Concerning the Application of the Paris Convention to Nuclear Installations in the Process of Being Decommissioned".
	Section 303 also ensures that, where a nuclear site licence is varied to remove what would otherwise be a relevant disposal site from the licence, the duties in section 7B of the Act apply to the operator of that relevant disposal site.
