Think that's a bit on the low side. Wink


Yeah I was quoting from the wiki entry - I doubt the government will release full details for some time yet - but nevertheless 2Mw is a fair amount of power from a reactor core about the size of a wheeleybin!

Yep, more than a little under. To give an idea of what a mega Watt is the Waverley paddle steamer (not a exactly a big ship, about 700 tons and 16 knots) is close to 1.5MW.

The light at the end of the tunnel is just another mine explorer.

I am off grid and installed a micro-hydro system to supply our house. It has required minimal attention and works 24/7, producing 12.5Kw hours of electricity a day, more than enough for our needs. These systems do work, it is only a shame that such plants could not be installed on the existing weirs for defunct mills, but the amount of surveys and licences required would make it too expensive.
The Milwr tunnel, however is a non starter as impounding it could cause major problems.

The H Core PWR2 is allegedly around 48-50 megawatts

Shome Mishtake Surely.

Most hunter-killer submarines have wet steam turbine main propulsion rated at around 30,000-40,000 shp which translated is about 22-30Mw. Wikpediaring Trafalgar Class subs gives a figure of 2.3Mw for the main turbo-alternators alone. There is also a deisel generator backup at about 1.5Mw. I think that this is the figure you are looking at - +30Mw from a wheeelie bin sized piece of kit is indeed pretty good!

The H Core PWR2 is supposedly 6 times the megawatt output of the PWR1 originally fitted to the Trafalgars.

Figures aren't readily available but thats what is generally reckoned upon, the orginal PWR1 output being around 11 megawatts and PWR2 being six times that could put output at closer to 60 megawatts
For 25 years without refuelling.....

Got a tour of Brittany Ferries' Normandie's engine room on the way back from France a few months ago, apart from it was probably far better than the on board entertainment of note was that it's four engines were running at 90% and this equated to about 24MW of power and close to 1000 litres of fuel an hour. The three generators could kick out 3MW together and they had to start one of these just to operate the bow prop.
