Shrouded in doubt: safety issues at Russian-occupied nuclear stations in Ukraine

Kate Brown and Susan Solomon: One thing nuclear power plants weren’t built to survive: War. Military strategists commonly target the enemy’s electrical grid. That’s a problem when combat is in a nuclearized country like Ukraine.

Inside the New Safe Confinement at the decommissioned Chernobyl nuclear power plant in Ukraine in 2021, The structure encloses the radioactive remains of the reactor that exploded in 1986. Russian
forces are now in control of the site. The day Russia invaded Ukraine, Russian forces took control of the decommissioned Chernobyl nuclear power plant.

A week later, flares from Russian artillery lit up the Zaporizhzhia plant; Ukrainian media reported that the Russian army had placed land mines around the plant’s perimeter and was stockpiling arms at both nuclear installations. The army is now pointed at yet another nuclear facility, the South Ukraine plant.

But Russia’s is the first invasion of a country that derives more than half its energy from nuclear power. It stands to reason that Russian generals will seek to capture all 15 active reactors in Ukraine. The Russian army appears to be using the nuclear installations as safe havens, calculating that the Ukrainians will not fire on them, but we can still expect plenty more fearful nights spent riveted to scenes of battles over huge concrete towers and rows of basins filled with radioactive spent nuclear fuel:

It turns out that reactor containment buildings have never been stress-tested for blows from heavy artillery or missiles. Even without a direct hit on a reactor, we are learning of the fragility of nuclear power plants. Normal oversight and operations have essentially been replaced by isolation and disorder.

Workers at Chernobyl have been on the job continuously for more than three weeks. They have no
clean clothes (important for nuclear workers), no real beds, no contact with family, no proper meals or rest.

At the Zaporizhzhia plant, according to a Ukrainian official, Russian soldiers have forced employees into
submission. Employee-hostages — exhausted, hungry and stressed — could make mistakes. So could the untrained Russian military personnel who aregiving the orders. Communication to these sites is largely cut off.
Independent oversight experts cannot enter to verify safe operations or deliver spare parts. Russian diplomats continue to enjoy a privileged role at the International Atomic Energy Agency, despite the war. We have to rely on what the IAEA and the Russian army tell us.

In the past, Soviet nuclear information services specialized in secrecy and mistruths. One of us, while
working on a history of Chernobyl, found that the IAEA had difficulty acknowledging the public health impact of the fallout from the 1986 explosion there. Russian information services again appear to be opaque and untrustworthy. If an accident occurs, we don’t have confidence that rescue squads and firefighters can get to captured nuclear installations to deal with infernos and injuries. Nor can we be sure that we will learn the full extent of the damage and spread of radioactive sources.

Danger of radioactive disaster at Chernobyl and other nuclear sites, with exhausted staff, and risk of loss of remote control

The staff, who are still at the Chernobyl nuclear power plant, came in on
February 23. The enemy has not allowed any opportunity to change the staff,
who are psychologically and physically exhausted due to the lack of
rotation and the constant pressure caused by armed people.

This can lead to loss of control over the safety of the facility and the inability to
respond to internal and external initial events such as fire, which in turn
can lead to severe radiation effects. In case of a complete power outage,
there is a risk of disabling the safety of important systems and equipment,
in particular: ventilation, heat dissipation, technological, and radiation
control systems.

The possibility of remote control over nuclear and
radiation safety indicators at storage facilities, the New Safe Confinement
facility, and other facilities will be lost. Operators will be unable to
control the level and temperature of water in spent nuclear fuel storage
pools. There are long-lived radionuclides in the spent nuclear fuel
storage, which in case of an accident can get into the Kakhovka Reservoir,
and further along the Dnipro river into the Black Sea. A huge area would be
contaminated by radiation for thousands of years. If there is an accident
with one power unit or one container for spent fuel, depending on the
direction of wind the radioactive cloud will affect Russia, Bulgaria,
Greece, Romania, and other border countries.

Safety fears, as Chernobyl nuclear staff tired and stressed.

As Russian troops hold staff at the Chernobyl nuclear plant ‘hostage’,
the mayor of a nearby town warns ‘complete catastrophe’ could be round
the corner. Yuri Fomichev says fuel is running out at the site, including
for back-up generators supplying its safety systems. With the plant being
besieged for three weeks now, food supplies are also becoming scarce, and
the stress of being held at gunpoint could lead to ‘a new accident’, he
adds. His concerns were echoed by the official in charge of a 19-mile
Exclusion Zone around Chernobyl who warned staff were ‘on the edge of
their human capabilities due to physical and emotional exhaustion’.

 Chilling warnings that Chernobyl is in danger of a new nuclear accident
because the 100 staff at the stricken plant being kept ‘hostage at
gunpoint’ by the Russians are on the edge of collapse.

What next for Ukraine’s nuclearsites and Wylfa and Trawsfynydd?

Dylan Morgan, on behalf of CADNO a PAWB. What next for Ukraine’s nuclear
sites and Wylfa and Trawsfynydd? The war in Ukraine has highlighted the
danger of the rush to build new nuclear power stations in Wales.

Russia’s miltiary attacks on Ukraine have been terrible. However, there is one
frightening fact about this conflict that isn’t mentioned in the press.
This is the first war to be fought on the land of a country that has
operational nuclear reactors.

In fact, Ukraine gets about 52% of its
electricity from 15 nuclear reactors. During the first days of the Russian
invasion, their chosen path into Ukraine to the south from Belarus was
through the exclusion zone around Chernobyl’s old nuclear reactors.
Higher levels of radioactivity have been reported in the area because
Russia’s heavy military vehicles have stirred up dust and mud releasing
radioactivity in to the environment.

Russian forces succeeded to gain
control of the site. Reports are reaching us suggesting that Ukrainian
workers trying to keep the site as safe as possible are under great strain.
It was reported that about 200 of them had to stay there without rest
facilities for the first fortnight after the arrival of the Russian forces.

Within days, we heard about Russian forces attacking the Zaporizhzhia
nuclear site in south east Ukraine. This is the largest nuclear site in
Europe and is the home to six Soviet 950MW reactors. That is, six Wylfa
size stations alongside each other. Luckily, neither the reactors nor the
waste stores there were hit. But great damage was caused to a training
building on the site. Russian soldiers have also captured this site. It is
logical to presume that work conditions there are very difficult for
Ukrainian workers in trying to run three of the six reactors with movement
to and from the site controlled by the Russians. It appears that the 3
other reactors there are not in operation at the moment.

We can only hope
that the names of the other nuclear sites, Rovno (4 reactors), South
Ukraine (3 reactors) and Khmeinitski (2 reactors) don’t become well known
as military targets hit by Russia over the next weeks. Dr Jim Green from
Friends of the Earth Australia warns us about dangers apart from the
reactors themselves in an article in the Ecologist two weeks ago:-
“radioactive reactor cores whether kept in situ or removed from the
reactors – would remain vulnerable, as would nuclear waste stores. Spent
fuel cooling ponds and dry stores often contain more radioactivity than the
reactors themselves, but without the multiple engineered layers of
containment thar reactors typically have.”
