ANS member Dr. Christopher Morrison was a recent guest on The Space Show. Dr. Morrison covered space radiation, lifetime radiation limitations, legal limits, rodent GCR and radiation experimentation, terrestrial radiation simulations, space nuclear power & propulsion, super-cooling conductivity.

Previous articles in this series were published on November 8 and November 14; this is the third and final installment of the series, which concludes just prior to the 60th anniversary of President Eisenhower's famous "Atoms for Peace" speech.  That speech, whose official title was "Atomic Power for Peace," was delivered to the General Assembly of the United Nations on December 8, 1953 and its ramifications for the future of civil nuclear energy the world over were immense.

Shortly after 11 a.m. on Tuesday, May 7, 2013, the operators at Dominion Resources' Kewaunee nuclear power plant opened its output breaker, disconnecting the turbine generator from the grid for the last time after just under 40 years of operation. Shutdown of the reactor followed, and the plant entered what for some is an uncertain (even if pre-ordained) future-a long-term storage period, followed eventually after many years by the complete dismantling and removal of the plant.

Plus a few pointers to what's in store for 2013

Restart of the nation's nuclear reactors will be guided by its actions

On September 11, the National Nuclear Security Administration (U.S. Department of Energy) hosted a public meeting in Chattanooga, Tenn., concerning its Supplemental Environmental Impact Statement on the disposition of surplus weapons-grade plutonium as mixed-oxide (MOX) fuel for use in power reactors. You may have seen the ANS Call to Action for the hearing and perhaps read the ANS position statement or background information.

Implementation of the energy policy announced last week will keep reactors running well into the second half of the 21^st century.

The weekly Carnival is the collective voice of blogs by many of the Internet's foremost nuclear experts and advocates, who continue each week to tell the story of nuclear energy around the World Wide Web.

When the heat released by nuclear fission is used in a steam plant to produce mechanical power, the second law of thermodynamics dictates that a large part of the heat must be rejected to the environment. Most land-based nuclear plants reject heat by using cooling water from a river or ocean.

When I was registering for the various events scheduled to take place during the ANS Annual Meeting this past June, I was quite excited to see that one of the three technical tours would be at Exelon's Dresden Nuclear Station, not too far from downtown Chicago where the meeting was taking place. Luckily, I made the cut for attendance and was issued a ticket for the tour when I checked in at the meeting desk.

An image sent by NASA's Curiosity rover shortly after landing

The nuclear-powered roving robotic laboratory Curiosity touched down early on August 6, and is beaming back images while undergoing system checks. The Curiosity landing has generated worldwide interest, including interest in its plutonium power source.

This article is the first in a series of info-graphic presentations about nuclear energy. This graphic compares the energy density of nuclear to that of wind power.
