The fifth and final day of Nuclear Science Week is all about Nuclear Medicine. Have you ever experienced a procedure at a hospital that employed radiation? Did you know that there are actually many different ways that nuclear technology is employed in medicine-and not just at your local hospitals?

Day 4 of the annual National Nuclear Science week is all about Nuclear Safety.

The third day of National Nuclear Science Week is focused upon the production of energy by nuclear means-and that means energy that can do work for man. Electric power, steam for heating businesses and homes, and mechanical power for propelling ships are perhaps the best known examples of man's use of nuclear energy.

The second day of National Nuclear Science Week promotes the knowledge of careers in nuclear-related fields.

Monday, October 20, marks the first official day of National Nuclear Science Week-a week long, annual coordinated educational event that promotes nuclear science and technology.

• What - American Nuclear Society Winter Meeting 2014

The 230th Nuclear Energy Blog Carnival has been posted at the AREVA Next Energy Blog.

This past week, a remarkable article was printed in The Atlantic, which gave a full first-person account of the initial trial run of the STR Mark I nuclear prototype plant-the plant that paved the way for the success of the first nuclear powered vessel ever built, the submarine USS NAUTILUS.

Shortly before midnight on September 26, 1944, a sustained chain reaction was begun for the first time in a nuclear reactor whose purpose was not merely to prove that fission could be achieved or sustained. The brand new reactor at Hanford Engineer Works, Washington state, had only been complete for about a month; its first uranium fuel had begun loading only on September 13. Incredibly, this facility, of a nature that had never been attempted before (as man had only been aware of fission, itself, for less than a decade) was built in the incredible time span of 11 months; ground had been broken to build the reactor building in October 1943.

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.

• This week the GE-Hitachi ESBWR design received its Design Certification from the Nuclear Regulatory Commission.

I'd like to take this opportunity to ask you a question: Have you considered attending the American Nuclear Society's Winter Meeting yet? Before you answer, I'd like to give you a few compelling reasons to do so from my own personal experience.

Yesterday, the saga of nuclear energy in post-Fukushima Japan reached an important milestone as the final utility that owns nuclear power plants in that country applied to the regulator for restart, in an event that snuck under the radar of most news venues.

It's time for the 221st edition of the Carnival of Nuclear Bloggers and Authors.  This event circulates among the top pro-nuclear blogs, and each week highlights those items submitted to the host as most important or most timely.  Of course, every week, there is a post made right here at ANS Nuclear Cafe to direct you to the Carnival - but on a rotating basis we host it here, and this week is one of those occasions.  Let's go in!
