Cracked nuclear fuel rods

A nuclear power plant in China owned by the companies developing new power stations in the UK has been shut down for “maintenance” after cracks were found in fuel rods.

China General Nuclear (CGN) said the reactor at the Taishan plant, about 80 miles west of Hong Kong, was safe and under control, and the damage was within the “allowable range”.

The problem is more likely at the plant that made the rods than with the reactor……or with the design or operation of the reactor that is.

    “… the damage was within the “allowable range”.”

    Given China’s track record on open and honest regulation if I was in the area I’d be looking at ways of getting out for a few weeks, at least.

    I’m 80 miles away and I’m not keen…. although the weather tends to come from the East here.

  3. Damaged fuel rods found in reactors in Germany.

    Reason?

    Wind power is intermittent and unpredictable but gets priority. Reactors are best at proving base load, meaning they run at a continuous, steady output. Inside it gets very hot, the cases of the fuel rods get very hot and expand. For maintenance, the reactor core and thus fuel rods cool slowly.

    However having to make way for wind power and act as back up means they do not run continuously so the rods cool and then reheat repeatedly over relatively short periods causing stress in the metal casings.

  4. There are many definitions of quality. High class. Absence of variation. Fulfilling a specification. Fit for purpose. In China it means “What you can get away with”.
