Several news items have come in this week which have one common theme - nuclear energy operation on the water.

The accident that occurred at Three Mile Island on March 28, 1979, brought about many changes to the nuclear industry. Among the changes was the industry stopping to reflect on current procedures and the training of its employees. Exhorted by the findings of the Kemeny Commission and sponsored by the Department of Energy, industry leaders and training personnel began meeting on improvements to training at the Gatlinburg Conference in the early 1980's.

Nucleoelectrica Argentina S.A. announced in July that it had entered into a contract with China National Nuclear Corporation to build a Chinese-sourced version of the traditional Canadian CANDU reactor at its Atucha site. This 800-MWe plant will be the fourth at the site (already occupied by two Siemens pressurized heavy water reactor plants, and the just-begun CAREM Small Modular Reactor plant) and the nation's fifth nuclear plant overall (adding in the CANDU plant at Embalse.) This new unit will be Argentina's most powerful nuclear unit, topping Embalse by 200 MWe.

A second nuclear IPO also is announced

The question is how big is the bird and will any of the proposed deals fly?
