Une faille de la taille d’une tête d’épingle a été découverte sur le réacteur. Cette faille a occasionné une fuite d’eau radioactive d’environ 37 litres par heure. Le réacteur a été arrêté et est en réparation. Les porte-paroles de l’université minimisent cet incident alors qu’il démontre objectivement la dégradation et la vétusté du réacteur en question.

Raleigh, N.C. — North Carolina State University officials said Thursday that there is a low-level water leak in the liner that surrounds the campus nuclear reactor, but that it poses no danger to the public.
University spokesman Keith Nichols described the leak, discovered Saturday, as the size of a pinhead and that it was leaking about 10 gallons per hour from the 15,000-gallon tank.
“This is a research reactor and considerably smaller than a commercial power reactor,” said Gerry Wicks, the university’s reactor health physicist. “Its design significantly limits the possibility that, even under the worst circumstances, this facility presents any kind of danger."
Nichols said it would be considered a public threat if the reactor were leaking at 350 gallons per hour.
The university is in the process of repairing the leak and has notified the U.S. Nuclear Regulatory Commission, North Carolina Radiation Protection Division and North Carolina Division of Water Quality about it, Nichols said.
The reactor has been in operation at N.C. State since 1972 and is one of about 20 university-operated reactors in the country. It is in operation about 1,000 hours annually for nuclear research, the school said.
The Nuclear Regulatory Commission inspected the reactor in February and found no significant issues.
