The Gordian Knot Of Grid Resilience – Part 2

April 9, 2018, 6:00AMANS Nuclear CafeSherrell R. Greene

According to the Roman historian Quintus Rufus, Midas's Gordian Knot was actually several knots so tightly entangled it was impossible to see how they were fastened.  The Gordian Knot of Grid Resilience is similarly constructed.  There's the Fuel Security Knot (how is "fuel security" defined?)  There are a series of knots related to the definition of and engineering approach to achieving generation system resilience, transmission system resilience, distribution system resilience, and integrated Grid system resilience. There's the Regulatory Knot - a real killer due to electricity market deregulation, entangled federal/state/local regulatory jurisdictions, and the demise of the vertically-integrated electricity provider. There's the Ownership Knot (most Critical Infrastructure in the U.S. is actually owned by the private sector).  There's a Tragedy Of The Commons Knot (when everyone is a stakeholder, but no one takes ownership of a problem).  I could go on.

The Gordian Knot Of Grid Resilience – Part 1

FirstEnergy's recent announcement of its intent to shutter four commercial power reactors at its Perry, Davis-Besse, and Beaver Valley sites is just the latest development in an escalating dialogue about electric Grid resilience and nuclear power's role in enabling and maintaining modern resilient societies and the resilient electricity supply systems upon which they depend. (Within this post, my definition of "Grid" is "the integrated system of U.S. generation, transmission, and distribution assets required to produce and deliver electricity to the end consumer".)

Women's History MonthWomen's History Month is a time to reflect back on the contributions of women, and to look forward to their potential. In nuclear science, there is a rich history of female physicists and engineers contributing to our field along with their male counterparts. From the radium to radioimmunoassay to reactors, women have defied the odds to become leaders in all areas of nuclear science and engineering.

The Glenn T. Seaborg Congressional Science and Engineering Fellowship

March 24, 2018, 6:00AMANS Nuclear CafeDr. Ruth Weiner

Any ANS national member, who is a U.S. citizen, with an M.S. or equivalent experience in nuclear engineering, nuclear science, or a related field, can apply for the Glenn T. Seaborg Congressional Science and Engineering Fellowship. The Seaborg Fellow serves as a staff member in the Congressional office of his or her choice, providing scientific advice to the member of Congress and his or her staff. The 12 months of service starts on January 1 and ends on December 31.

Lunchtime at ANS Conference Leads to Innovative Course Collaboration

March 16, 2018, 8:11PMANS Nuclear CafeTiffany Adams

For most working in the field of nuclear energy, the American Nuclear Society conferences are frequently attended to learn about the latest innovations, present their newest research, and spark new hypotheses. But the best ideas aren't always found in the lecture halls. In the case of the latest collaboration between Idaho National Laboratory (INL) and Oregon State University, lunchtime was the breeding ground for innovation.

Seeking Justice for E=mc2

albert-einstein-62931_1920In February of 1950, a devoted follower of Albert Einstein wrote him a letter prompted by the death of his son. He questioned Einstein's belief that physical death cannot be transcended. His grief could only be overcome if Einstein were to endorse a theory wherein his love for his son would render the latter immortal [1]. Einstein wrote back to the grief-stricken father, grimly but pragmatically choosing to focus on nursing his mental health back to a more peaceful state, than on any theories about his son's death.

RadioNuclear.orgThere's been a ton of news since RadioNuclear.org's newest episode! ANS Social Media Team member and program host Doug Hardtmayer picked out three that had a lot to unpack, so  enjoy his extended news segment! The first item he discusses is the new MOU signed between the Ukraine and Holtec to build multiple SMR-160's in the Ukraine by 2026. Doug also discusses Mark Z. Jacobson's decision to drop the lawsuit against PNAS and Christopher Clack, and speculate some of the reasons he may have dropped the case. Lastly, Doug tackles a new Greenpeace study from Fukushima that will surely make its rounds in the anti-nuclear community, and discuss some questionable findings from this study. Doug's is joined this week by two senior-level board members from First Energy, owner of the Davis-Bessie and Perry Nuclear Power Plants, Ohio's nuclear future!

Fort St. Vrain in Pictures: 3

One of the important design goals for the Fort St. Vrain reactor - really, the second-generation high temperature gas cooled reactor - was to create a core design that would be more compact than that actually used at Peach Bottom.  An innovative design was developed using stacked reactor-grade graphite modular blocks which incorporated fuel rods that contained coated fuel particles.

The Fort St. Vrain project was innovative in more than one respect, and while it did not blaze the trail in HTGR (High Temperature Gas-cooled Reactor) commercialization - a feat accomplished by the Peach Bottom Atomic Power Station - it did considerably advance the technology toward full commercial operation and duplication on a wide scale through some significant design changes.  One of the most interesting of these was the use of a prestressed concrete reactor vessel (PCRV) for the reactor itself and primary components instead of a steel vessel.
