China about its first floating nuclear reactor: it is virtually indestructible – TechReen

We were informed about a similar project, this time by the Danish company Seaborg Technologies, in June 2021, but then only the concept was mentioned. According to the South China morning postChina’s floating nuclear reactors are operational and, according to their engineers, are “almost indestructible.” The plan to create this kind of unity was born in the Middle Kingdom in 2016, but only now have we learned the details about it.

ACPR50S is a floating marine unit weighing 30,000 tons, inside which there is a small nuclear reactor with the capacity of 60 MW. Its area of ​​operation is to cover the east coast of China – the reactor will power the local oil rigs and provide regular electricity supply to the inhabitants of the Pohaj Strait, a less developed part of that region.

Furthermore, the floating reactor is part of the Chinese push to phase out carbon and introduce solutions based on low emissions of CO2 or other pollutants, in line with the commitments agreed during the COP26 conference. The implementation of cleaner forms of energy is imperative for a country that is currently one of the largest emitters of greenhouse gases in the world.

Acpr50s replica tested

The tests themselves were conducted on a smaller replica of a floating nuclear reactor at an extreme weather simulation facility in Hubei province. Engineer Kong Fanfu and a team of scientists from the Design and research of the second Wuhan ship Institute have concluded that the ACPR50S will be able to generate electricity during a hurricane with the highest level on the Beaufort scale. During the first test, the force of the artificial wind exceeded the speed of 133 kilometers per hour, and in subsequent tests, this value increased by 50%. under additional stormy conditions (for example, waves).

The aftershock withstood this too and stayed in the base position for many hours, which was to be a safety confirmation for the entire Chinese floating nuclear reactor program. Some doubts arose about the ACPR50S mooring system, which is to support a load of 600 tons, which may be insufficient in extremely difficult climatic conditions. According to scientists from Wuhan University, under such conditions, the value of this parameter can be as high as 2,000 tons.

“A ship’s hull should not capsize under any circumstances,” tinning experts comment in the South China Morning Post, suggesting that This element may need to be strengthened and further testing done.. In addition, the Chinese floating nuclear reactor has been equipped with a number of safety functions, including for seawater cooling in the event of a power outageBut if the unit tips over, these functions may fail. As you can easily guess, this can have catastrophic consequences, with the biggest threat being “abuse or incompetence caused by insufficient employee training.”

The first floating Chinese nuclear reactor is scheduled to start operating in 2022, and the 2018 plans include information on a fleet of 20 units which will provide power in various parts of China. Time will tell if such a solution is profitable.

At the same time, we invite you to listen to the latest episode of the Technically Thing Taking podcast. This time, we spoke to guests about rising electricity prices and whether Poland is on the verge of a blackout.
