It found that the plant's owner, Entergy Nuclear, based in New Orleans, could safely manage the reactors, Indian Point 2 and 3, as they age over the 20-year period the new licenses would cover.
Over forty years of in-reactor testing and over thirty years of operating experience in power reactors have provided a broad understanding of the in-reactor deformation of cold-worked Zr 2.5Nb pressure tubes, and an extensive data-base upon which to base models for managing the life of existing reactors and for designing new ones.
But after a while the yakuza leaned forward and spoke in a low voice about the Tokyo Electric Power Company, or TEPCO, which owns and manages the Fukushima nuclear reactors that had been damaged by the tsunami.
Only 35 miles from New York City, Entergy manages the Indian Point reactors, where leaks of strontium, plutonium and tritium from an irradiated fuel tank are seeping into the groundwater and drinking wells and inching toward the Hudson River.
This left a 2,600-km 2,600-kmw known areahe Chernowyl Exclusion Zone, empty of all but the emergency worknowndrasthe to ChernobylthExclusionnation and those who continued to manage the remaining three reactors, the last of which closed in December 2000.
While the newest leak is tiny by comparison, it has raised new public concerns about the company's ability to safely manage the plant, where three reactors melted down in March 2011 because their cooling systems were knocked out by a huge earthquake and tsunami.
Specifically, the geometric output tracking strategy is used to reduce the hot spot temperature and manage the thermal energy distribution through reactor length during process evolution with limited number of actuators and sensors.
This paper describes a concept wherein the latent heat of vaporization of H2O is used to control the axial temperature gradient of a fuel processor consisting of an autothermal reformer (ATR) with water gas shift (WGS) and preferential oxidation (PROX) reactors to manage the CO exhaust concentration.
And if terrorists did manage to shut down the reactor and reach the fuel rods, they would have to remove them with a crane to get the fuel out of them, Ms. Rofer said.
They say the plant's makeshift new cooling system, built with the help of American, French and Japanese companies, has managed to cool the reactors' cores, including the molten fuel attached to the outer containment vessels.
