Part 1: Nuclear Energy Generation Projects: Regulated Asset Base Model Section 9: Expiry of modifications made under section 6.
This section sets out the consequences for licence modifications made under section 6 in the event the designation of the nuclear company in question expires, or if its designation lapses or is revoked.
	Subsection (1) states that this section is only applicable if the designation of a nuclear company ceases to have effect because the designation has expired, lapsed or been revoked. In other words, it does not apply where a nuclear company’s designation ceases to have effect in accordance with section 4(1)(b) because it has entered into a revenue collection contract with a revenue collection counterparty.
	Subsection (2) provides that if a nuclear company’s designation has ceased to have effect in accordance with the provisions set out in subsection (1), any modification which was made by the Secretary of State to the terms and conditions of the nuclear company’s electricity generation licence, under the power in section 6(1), will be treated, from the ‘relevant time’ as never having been made. Under subsection (3), the same applies to any modifications made under section 6(7) in consequence of, or for purposes incidental or supplementary to, the relevant modifications under section 6(1).
	Subsection (4) defines "relevant time" for the purpose of subsections (2) to (3). It means the time when the designation of the relevant nuclear company ceases to have effect.
	Subsection (5) obliges the Secretary of State to publish details of the fact that modifications are to be treated as not having been made under subsection (2) or (3).
