Calls to make Calder Hall the first nuclear reactor in the UK to be decommissioned

Whitehaven News 5th Feb 2019 , CALLS are growing to make Calder Hall the first nuclear reactor in the UK
to be decommissioned. Nuclear officials say that if decommissioning is
delayed, the asbestos in the reactor will pose a risk to workers, while
maintenance costs will become ‘unsupportable’.

Council bosses are ramping up the pressure on the Government to fast-track the dismantling of the world’s oldest industrial-scale nuclear power station based at
Sellafield. The authority’s nuclear board will be asked today to delegate
authority to council chief executive Pat Graham and the nuclear
portfolio-holder councillor David Moore to develop a detailed case for
accelerated decommissioning.

Councillors agreed at the end of last year
that the UK’s first industrial-scale power station to be built should
also be the first to be cleaned up. Calder Hall is one of 11 reactor sites
around the country and the Nuclear Decommissioning Authority is now
reviewing the “timing and sequence” of its nationwide clean-up
operation.

At present the defuelling of Calder Hall is due to be finished
in 2019/20, and would not enter a care and maintenance (C&M) status until
2034. The argument for tackling the Sellafield-based reactor first includes
the continuing risk it poses to workers and the public. The report said:
“As the oldest Magnox reactor, the deterioration of the building fabric
and the potential for significant quantities of asbestos to be present pose
risk to workers. The cost borne by the taxpayer associated with maintaining
the building in a safe state for a long period of care and maintenance
could be significant and could increase over time to meet future regulatory
requirement.”

The report concludes that the reactor could deteriorate to
the point that the cost of keeping it compliant with environmental
regulations becomes “unsupportable”. The accelerated clean-up of Calder
Hall could also create jobs to offset some of the 3,000 “surplus roles”
expected at Sellafield over the next four to five years.

Energy efficiency – theme for July 2019

Energy efficiency represents the single largest potential contributor to global emissions reduction, according to the International Energy Agency (IEA 2017). It should be a key part of the global energy strategy, for several reasons:

It could reduce global electric demand by more than 20 per cent, based on current rates in the U.S. power sector, while maintaining high levels of services such as heating and lighting.
It avoids the need for increased energy, capacity and grid services, making it the least expensive way to decarbonise at scale.
It can reduce carbon dioxide emissions by billions of tonnes.

A dramatic example of the power of energy efficiency is lighting. In 2017 the United States passed the milestone of 1 billion LED and CFL lights installed, avoiding 142 million tonnes a year of carbon dioxide emissions, at a cost of about $7 per ton of avoided carbon dioxide. In contrast, the cumulative installed capacity of rooftop solar reached 8,000 MW in 2017, saving 8 million tonnes a year of carbon dioxide, at a cost of $360 per ton. Lighting efficiency thus yielded almost 18 times the avoided carbon dioxide, at about 2 per cent the cost per ton of rooftop solar.

Google provides another example of the power of energy efficiency. Its data centers now use 50 per cent less energy than the average data center, according to the company. Google also developed an improved chip, the TPU, which performs 83 times better than standard CPUs. The new chip allowed Google to reduce power consumption at its data centers by a factor of 30—far exceeding the effect on Google’s carbon footprint of all of the company’s renewable energy purchases. ” – John Woolard, Eco Business, 10 June 2019
