Five questions on Helicopter Pad at Hinkley Point

Information released

1) What are the regulations or guidelines governing the frequency and admissible purposes of helicopter landings and take-offs from the Hinkley Point nuclear complex in West Somerset, and what distance is the landing pad from the Hinkley A and B reactor buildings.

The Air Navigation (Restriction of Flying) (Nuclear Installations) Regulations 2007 govern restrictions on flying around nuclear installations.

Regulation 3 places restrictions on flights within a cylinder with a radius of 2 nautical miles and to a height of 2000 feet from the centre of the Hinkley Point site.

Regulation 4. however states that:

  1. Regulation 3 does not prohibit at a nuclear installation specified in paragraph (2), flight for the purpose of landing at or taking off from the helicopter landing area at the installation with the permission of the person in charge of the installation and in accordance with any conditions to which that permission is made subject.
  2. Paragraph (1) applies to the nuclear installations at Aldermaston, Barrow-in-Furness, Berkeley, Bradwell, Burghfield, Chapelcross, Dungeness, Hartlepool, Harwell, Heysham, Hunterston, Hinkley Point, Oldbury, Sellafield, Sizewell, Springfields, Torness, Trawsfynydd and Wylfa.

The landing pad is on the Hinkley Point C site c 600m from the Hinkley Point A Reactor Buildings and c 800m from the Hinkley Point B Reactor Buildings.

It should be noted that the Hinkley Point C planning permission constraints also apply to non-emergency commercial helicopter landings, restricting its use to 5 two-way flights each calendar year
