Talk:Hinkley Point C nuclear power station

How high above sea-level are the reactors? — Preceding unsigned comment added by 66.30.55.165 (talk) 21:39, 14 October 2017‎ (UTC)

According to this ref it is to be built 14 meters above sea level and located slightly inland, with a 900 meter long seawall that will be 13.5 meters tall.

Writing this after the second Reactor Pressure vessel was delivered, should this be added to the to the timeline on the article or would this be considered relatively unimportant? Galdorfia (talk) 19:47, 14 January 2026 (UTC)

The turbine speeds for Hinckley Point A and B are quoted as 3000rpm, but for Hinckley Point C as being "around" 1500 rpm. I'm querying the use of the word "around". The generators are almost certainly synchronous alternators which are essentially rotating electromagnets which synchronise with the 50Hz frequency of the UK National electricity Grid, with a two pole alternator synchronising at 3000rpm and a four pole alternator synchronising at 1500 rpm. Other technologies are theoretically available but would be considerably more expensive, and it's unthinkable that the engineers would take a risk with a different untried technology. Four pole generators are feasible and have a precedent for very large unit such as at HPC. Being pedantic the grid frequency does vary by a few tenths of a percent, depending on the supply and demand for electrical energy at any point in time, so the speed is not precise. The way the information is presented should be consistent between the three power stations. ~2026-29359-06 (talk) 14:31, 16 May 2026 (UTC)
