Via Japan Today, a report that has nothing to do with Fukushima but a lot to do with safety hazards in nuclear plants all over the world: Pipes inside condenser found damaged at Hamaoka nuclear plant.
Damage to pipes inside a turbine steam condenser has been discovered following the leak of seawater into a reactor at the Hamaoka nuclear power plant in Shizuoka Prefecture, its operator Chubu Electric Power Co said Friday.
The utility will investigate the cause of the damage as the pipes, measuring 3 centimeters in diameter through which cooling seawater flows in the condenser, may have fractured.
According to the utility, recirculation piping for adjusting the water volume inside the reactor is laid next to the damaged pipes and a metal lid measuring about 20 cm in diameter and weighing around 3.5 kilograms was found to have fallen nearby.
Chubu Electric suspects the metal lid may have hit the pipes when it fell and is examining other pipes in the condenser.
About 5 tons of seawater may have entered the No. 5 reactor at the nuclear plant, following the discovery of about 400 tons of seawater in the condenser while work was under way last Sunday to put the reactor into a state of ‘‘cold shutdown, according to the utility.
When they say 5 tons of seawater may have entered a reactor, the uncertainty makes me nervous.
