by burning coal, natural gas, wood

fuels and peat. While many Finnish

cities have progressive climate policies

and goals, they have struggled to

decarbonise heating and liquid fuels,

the society said. Rauli Partanen,

vice-chair of the society and an independent

energy analyst and author,

said there are “significant economic

possibilities” in producing combined

heat and power (CHP) with nuclear

reactors. He said: “With CHP, the

reactor could produce roughly twice

the value per installed capacity compared

with just electricity production,

while at the same time decarbonising

heat production.” He said nuclear

is great for baseload needs, but

with advanced technologies such as

high temperature reactors and high

temperature electrolysis, nuclear can

also be used to decarbonise not just

electricity, heat but also transportation

fuels and many industries”.

EDF ‘Cannot build new

reactors in France without

guarantees’

(nucnet) French state-controlled

utility EDF can no longer build new

nuclear reactors in France without

state support, chief executive officer

Jean-Bernard Levy was quoted as

saying in an interview with the Ouest

France daily newspaper. Asked when

EDF could build new reactors at home,

Mr Levy said: “Henceforth, we cannot

build new reactors without adequate

regulation providing guaranteed

income”. He said the Flamanville-3

EPR project under construction in

northern France began at a time of

high power prices and that now all

power sources, nuclear as well as

renewables, need to get “the same

visibility on sales prices”. For its

project to build two EPRs at Hinkley

Point in the UK, EDF obtained an

EU-approved state-guaranteed price

of £92.5 per MWh over 35 years,

which is above current market prices.

The government of French president

Emmanuel Macron is planning to close

old reactors to reduce the share of nuclear

energy in French power generation

to 50% by around 2035 from 75 %

today. Mr Levy said EDF expects to get

approval to load nuclear fuel at

Flamanville-3 at the end of 2018.

Japan’s Regulator:

Kashiwazaki Kariwa-6 and -7

meet new safety standards

(nucnet) Units 6 and 7 of the

Kashiwazaki Kariwa nuclear power

station in Niigata Prefecture, northwestern

Japan, meet new regulatory

standards imposed after the March

2011 Fukushima-Daiichi accident, the

Nuclear Regulation Authority said.

The two units, owned and operated

by Tokyo Electric Power Company

(Tepco) are the first boiling water

reactors to meet the new standards.

Tepco also owns the Fukushima-

Daiichi station.

Kashiwazaki Kariwa was not affected

by the March 2011 earthquake and

tsunami which damaged Fukushima-

Daiichi, although the station’s seven

reactors had all been offline for up to

three years following a 2007 earthquake

which damaged the site but did

not damage the reactors themselves.

While the units were offline, work

was carried out to improve the

facility’s earthquake resistance.

Accord ing to JAIF, the governor of

Niigata Prefecture, Ryuichi Yoneyama,

has said he will not discuss restarting

the two units until further information

about nuclear incidents and their

impact on public health is made available.

Both units are 1,315-MW BWRS.

Kashiwazaki Kariwa-6 began commercial

operation in November 1996 and

Kashiwazaki Kariwa-7 in July 1997.

Tokyo-based nuclear industry

group the Japan Atomic Industrial

Forum said 14 nuclear units have now

been approved by the NRA as meeting

the new standards. They are

Kashiwazaki Kariwa-6 and -7,
