You think the biggest cost for Nuclear is in it's design/implentation and operation?

They cost an absolute fortune to get rid of at the end of their useful life safely and make sure all the nasty's are taken care of properly to keep the green brigade happy. That's where the majority of costs for Nuke power goes.

As for the yanks, they've been doing this for years with proper carriers. If we were ever going to go Nuke on our CV's we should have done it in the 60's. Plus the US military is like a massive job creation scheme. The systems are available for a CV to be manned with very few people, yet the US still have crew's of 3500 (without CAG). The magazines alone have 400+ crew in them and the reactor has huge numbers too. QEC will sail with a similar size ships company to the CVS.

Finally, the latest US Carrier is costing (just to build, not dispose of) $13bn, the UK Government is getting two CV's for £6bn (guestimate as the CV conversion is still being assessed).

Personally I think we're getting a massive capability for very little money in real terms. It's a shame the government, the media and therefore the general public don't realise this.

that's not very accurate though.

people come up with all kinds of figures for de-commissioning, the reality is that this is pure guesswork and scaremongering, yes it's not cheap, but the kind of figures banded about are laughable, just how much fuel do you think these things have in them? even if you include all the low level stuff when they are scraped, it's not that significant, compared to the levels of low level nuclear waste the NHS generates.

Yes, I agree, dry dock facilities are a bit of a sticking point, however, realistically, if we are going to have a viable navy, don;t you think we should have this kind of facility anyway?

(if we can justify it for a single class of sub, what is a ship any different?)

their new carrier has cost some $9Bn in design, not making it, currently they are something like $4-5Bn build cost.

I agree, I just wish they would stop fannying around and build them, the longer they take, the more it costs and the more compromised they become.

as an example, MS Queen Elizabeth cruise ship at some 91,000 tonnes (ie, half as much again as the Queen Elizabeth class aircraft carrier) took 15 months from Laid down to in-service and cost ~£350M, now, I appreciate an aircraft carrier is a little more complex in some respects than this, however, how the hell does it suddenly cost north of £3Bn - ie. almost 10x the amount?

and before somebody goes on about one off's etc, cruise ships this size are hardly mass-produced.

the difference is that this is commercial building, with commercial budget's and controls, and without the goal-posts continually being moved.

It's not just job creation. They have a different operational philosophy to the UK. Their stance used to be - although things are changing - that a man is more reliable than technology - especially when factoring battle damage. Automation and RO kit is cheaper in the long run than a billet though so we don't really have the option unlike the US with their very deep pockets.

On the topic of costs. According to the NRC you're looking at 400-500 million dollars for a civil reactor to be decommissioned fully. Astute's costs were (according to wiki £3.9 billion for the first three boats. That doesn't include the running costs of the R-R design authority, and the nuclear specific elements of naval bases. Design and Justification costs more than you think.

With regards to the nuclear propulsion side of things, there is a nuclear facility of some sort at Rosyth, where QEC is being assembled in dry dock.

Not sure what sort of facility, but if they really wanted to make her nuclear, given the amount of investment in infrastructure elsewhere, at the dry dock itself in Rosyth, which was never big enough for the ship before they spent millions widening it, adding new doors, a new crane, etc, and at all the other build yards, it probably wouldn't have been that big a deal to create a re-fuelling facility at Rosyth?

However, as i understand it, the initial outlay was the main driving factor behind the GT/electric propulsion route, as opposed to nuclear.

Would have been ideal, but been shut (the NLC part) since 2001/2002. Decommissioning well under way now. The only nuke base in the North now is where the bombers live on the west coast - Faslane / Clyde.

ETA re the costs not being a big deal. Here's an exerptt from an article on D154 (which replaced Roysth)

At its peak, in August 2001, the D154 project employed 2,865 personnel. It is estimated that, at various stages, more than 100 separate contractors and 40,000 people were involved in turning the facility proposals into timely reality. This article provides an overview of the new facilities, which stand as a visible testimony to the efforts of all involved.

http://www.ingenia.org.uk/ingenia/articles.aspx?In...

Think how much 40k engineering consultants and the like cost per day. Then factor in the material costs for seismically qualified buildings, infrastructure etc. and that doesn't include any costs for the other infrastructure that would have needed to be in place that is already at Devonport.

Had they decided from the start that QEC was to be nuclear though, they wouldn't have shut it in 2001/2002. We knew about CVF from as early as '98. The fact that they've since shut the facility might not have been a driving factor in that decision. Might have been, but really, who knows?

It was way out of date though and would have needed a LOT of money throwing at it. Of course we could have done it but when looking at the pros and cons it comes down in favour of conventional for carriers. The balance shifts due to the air independent propulsion aspect when you look at subs though hence why we still have them.

The other factor of course is whether there would have been enough SQEP people to build it in Scotland? There was a big skills shortage for Astute due to the lack of throughput to keep people skilled. Anyone with those skills is probably working off shore for more money.

Off topic, If anyone wants to make a fortune over the next few years, get yourself certified to weld the stainless types used in primary secondary pipework.

Or doesn't want to work in the sthole that is Barrow!

Anyway, it seems we mostly agree on the reasoning.

I see QEC in the shed here on a daily basis, but i was in Rosyth recently, standing in the hangar taking a look at the weapons lifts, and man, it's a big boat!

Looking forward to seeing her finished. Although i'll need to find a new job!

No, i can't. But then, i'm not a welder, i'm a structural/stress/design engineer, whatever you want to call it.

You'd be surprised how many people have swapped. We used to have a lot of lads go out the offices to inspection work too. I think it was the lads in their 20s turning up in a nearly new Cayman or Exige that did it.

Pity you're in Scotland - R-R subs are always short of FEA bods.

I'll be spending more time in rosyth too as build progresse Doogz, starting next month with my first trip there. Have seen LB02 and am looking forwrd to geting on Superblock 3.

Also can't wait to be doing sea trials in a few years too!! biggrin It's going to be one hell of an experience.

Yeah, mainly, with one day a week in Frimley as part of Mission Systems.

isnt it going to be a massive problem for our navy if the scottish do manage to get independence? as they'll inherit our only nuclear refuelling depot?

There isn't one in Scotland any more. It was Rosyth and they started decom in 01/02. The subs are maintained/refuelled at Devonport. You're thinking of Faslane which is the home of the bombers, but even they're refuelled and maintained down south.

ASME and the French equivalent - can't remember what that acronym is now. I guess it will depend on whether EPR or AP1000 gets the nod - or both. UK is traditionally ASME though, but given EPR is French???

No idea of the detail beyond that in terms of specific methods and what grades. I used to have ASME specialists to provide that sort of info and it's five years hence since I was intimately involved with AMSE codes etc. I'm not a welder, just cognisant of likely future demand when new build kicks off in earnest.

There is the problem though of where the bomber fleet will reside if they force close Faslane. Unlikely due to the numbers it employs but who knows with an idiot like Salmon in charge.

For example, Dounreay would have been the perfect site for a new build - existing infrastructure, SQEP people, pro nuclear local population, would take up the slack in employment downturn as UKAEA site winds down, but no Salmon is anti-nuke. Silly IMO.
