Nuclear Medicine and Imaging: Supporting life where it matters most.

Did you know that nuclear technology has been used in space almost since the beginning of human exploration in space?  That's right - nuclear energy has been used to power science experiments, satellites, and space probes.  It may even be used someday to propel vessels with people on board to other planets.  Let's take a look at three basic kinds of nuclear space technology!

This week is National Nuclear Science Week - an exciting week of learning, teaching and interacting on all things nuclear-related.  (You can read about the history of National Nuclear Science Week, or NNSW, by following this link.)

Before diving deep into strategies for how to ace the Nuclear P.E exam, let's briefly review the three main reasons of why it's essential for nuclear engineers to pass the professional engineering (P.E.) exam.

On Episode 12 of RadioNuclear, we discuss how fear-mongering stories about nuclear power plants in the path of a hurricane are irrelevant, the Oyster Creek Shutdown, and lastly, how nuclear power should be used geopolitically.

There's no denying that nuclear energy in the United States has traveled a rough road over the past several years. Plants have closed, legislation to deal with nuclear waste has stalled, and at times it seems that nuclear energy has been written off by policymakers and the public alike.

This week has brought two news items - one positive and one negative - that echo a theme which runs down the history of nuclear energy like a spine.  The story goes that the original, longest-tried technology works while other, theoretically superior but technically vastly more difficult concepts continue to run into roadblocks; that story remains unchanged today, in the face of these new developments.

Last time, we looked at the U.S. Atomic Energy Commission's (AEC) findings on the drivers of nuclear plant construction delay and cost overrun up through 1969.  We'll complete our analysis of the AEC findings on 1969 in this installment and move on to 1970.

Hurricane Florence, a potentially devastating Category 2 hurricane is on track to make landfall in the Carolinas sometime within 24 hours after this morning, Thursday, September 13. With winds up to 130 miles per hour, Florence could be the most powerful storm to hit so far north in the United States - ever.

Another, modern-day report has come out which in part discusses the problems encountered in nuclear plant construction - and discusses some suggested fixes for these.  I welcome such research and reporting, but I have begun to wonder how many people realize that all of these studies have been done before and, more importantly, that the conclusions of those studies apply exactly to today's situation.

Japan announced for the first time that a worker at the Fukushima nuclear power plant died after suffering radiation exposure, as reported in the Guardian, BBC and Newsweek, although this is unlikely to be true.

Our latest Friday Matinee video is a fascinating time-lapse produced by Georgia Power to show the entire process of installing one of the two steam generators at its Plant Vogtle expansion.

A sharp increase in reporting on KEPCO (the national Korean near-monopoly electric power provider) and KHNP (Korea Hydro and Nuclear Power, the nuclear wing of KEPCO) the last two weeks or so by the Korean press has revealed a drastic reversal in the fortunes of this once-shining figure of Korean progress and success, and further implies ripples that perhaps could turn back an already flagging national economy.

Last week, the American Nuclear Society announced its new K-12 STEM education initiative Navigating Nuclear - Energizing Our World.

August 10, 2018, marks the 100th birthday of one of the great men in nuclear power: Vice Admiral Eugene P. "Dennis" Wilkinson USN. He passed away in July 2013, a month before his 95th birthday.

In this final installment of the series on pool reactors we'll take a look at some remarkable images found in a 1956 brochure which shows some of the steps of the process in constructing the Ford Nuclear Reactor and attendant facilities at the University of Michigan.  Under the leadership of Babcock & Wilcox (today, BWXT) this 1000 KWt facility was constructed in about 19 months.  Reviewing the previous article in this series will be helpful in relating the construction photos.

In 2012, the Mars Science Laboratory (MSL) [1] successfully touched down on the Red Planet. Aptly named Curiosity, it brought with it scientific discovery instruments and exploration capabilities that only a nuclear-powered rover could realistically possess.

Control Room, Naval Research Reactor, circa 1958.

In the previous installment, we observed that some of the earliest pool reactors incorporated their instrumentation right on the moving bridge which supported the reactor core.  As reactors increased in size and power and as exposure was considered, control was moved off the bridge onto the floor and then often into a control room (as seen above) in later designs.  These control rooms could either be at operating floor height with direct view of the reactor, or separate in another area of the facility.

From Part I, we learned that everything takes energy, and that removing steps in the energy conversion process can save energy. We even that there is potential to grow food directly with electricity. The question that arises from those suppositions is: how close are we to that reality?
