I spent decades in energy -Here are the problems with UK nuclear plans

IT is clear that the issue of Scotland’s moratorium on new nuclear power
will be a key battle line in May’s Scottish Parliament election. Anas
Sarwar has joined the Labour energy minister Michael Shanks in the call for
building more nuclear power in Scotland – and the electricity cables to
take the generated electricity to energy-hungry England. MP Shanks
continues to declare that he would be relaxed about having a small
modularised reactor (SMR) erected in his constituency.

I am not sure how
the good people of Rutherglen feel about this. What I find mystifying is
the lack of proper scrutiny being applied to the claims made by those
members of the Nuclear Energy All-Party Parliamentary Group and its
well-funded nuclear lobbyists. It does not surprise me that they are unable
to set out what configuration they favour, as the reactors which they claim
will produce 400 MWs do not exist. They have not been manufactured, tested,
or installed – anywhere! As an engineer, I would be keen to ask the
politicians if they have thought about some of the basic elements of a
power plant. Do they have any ideas what the thermal capacity of the
proposed reactors are? Have they understood what the cooling requirements
might be? How about the status of the “core catcher”, the system
designed to prevent a Chernobyl-type event?

Be under no illusion, Shanks,
Sarwar and the nuclear lobby are building a Potemkin village, a deceptive,
impressive facade. They of course don’t want to talk about the European
Power Reactor (EPR) configuration being installed at astronomical cost at
Hinkley C. This project is forecast to cost around £45 billion when it
finally comes online sometime next decade. It is not easy to get a proper
sense of this sum but it might surprise people to realise that this is the
equivalent of paying £1 million every single day for 120 years – and this
is just the construction cost.

We have not even started talking about
operational costs, asset management and asset decommissioning. When Julia
Pyke, the managing director of Sizewell C, was asked by the BBC how the
project was going, she answered airily that it is “on schedule and within
budget”. I waited eagerly for the obvious follow-up question – what is
the budget and schedule? – but that never came. If the Sizewell C
construction consortium defies recent construction trends and achieve a 10%
saving relative to Hinkley C, that would still indicate a £40bn project
cost – which is enough to build 130 hospitals similar to, for example,
Forth Valley Royal Hospital.

The supporters of nuclear energy tell us that
we need these plants for baseload capacity. They fail to acknowledge that
in Scotland we already generate more capacity from renewables than we
consume – and this surplus is only going to grow as we continue to see more
investment in wind, solar, tidal and energy storage.

“What about
intermittency and the lack of system inertia?” is the nuclear advocates’
stock question when discussing the growth of renewables. This is a
legitimate question but the answer is beautifully simple – we will continue
to do what we do now, rely on combined-cycle gas turbines (CCGTs). Which is
reassuring as there will be no nuclear plant coming on stream anytime soon.

“But what about net zero?” might be the next question. Thankfully,
there are a raft of solutions to this currently available and more coming
on stream every week. For example, gas turbine manufacturers are building
on 50 years of experience of burning hydrogen and will be ready to burn
hydrogen or blended hydrogen/methane as quickly as the hydrogen market can
come on stream. My prediction is that the hydrogen market will come on
stream faster than any SMRs can be built – and if UK politicians had a
strategic bone in their bodies, they would be trying to beat our friends in
Europe to win the hydrogen race.
