An October 4 shut down at Brazil's 690MW Angra I nuclear plant did not figure on the 1-7 international accidents scale, and the plant only stopped producing for a few hours, nuclear power committee (CNEN) advisor Rogerio Gouveia told BNamericas.com.
"The event only caused a stir because in May there was an accident that was classified as Level 1 on the scale, when radioactive liquid leaked, which was not communicated to the population at the time because there was no danger," he said, adding that "the press is now very attentive to what happens at Angra I, especially as the government and parliament are discussing whether to construct Angra III," Gouveia said.
The October 4 incident happened as a result of a defect in a water valve indicator in the security tank with radioactive liquid, which was dealt with in a few hours, and the plant restarted operations in the afternoon of the same day, he said.
The May incident happened after employees failed to close a valve, which caused a rise in internal pressure, followed by the release of slightly radioactive liquid into the reserve security tank, which was placed in the plant's container.
From now on the public will be informed of all such incidents at Angra I and the 1,300MW Angra II plant, Gouveia said.
State company Eletronuclear runs Angra I and II in the Angra dos Reis nuclear complex, on the south coast of Rio de Janeiro state.
