ANS Connecticut Section Speaker Meeting Announcement for October 23rd, 2014

Development of a Zirconium Hydride Moderated Molten Salt Fueled Reactor

Please join us in welcoming Dr. Leslie Dewan, co-founder and Chief Scientist of Transatomic Power, who are developing a new, thermal-spectrum molten salt reactor concept that uses zirconium hydride as a moderator and LiF-(Actinide)F4 as fuel.  The designs builds on the work conducted in the Molten Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory in the 1960s.  The new salt and moderator used in this design gives the reactor a twenty-fold power density increase as compared to the MSRE, and allows for the use of spent nuclear fuel or low-enriched uranium (1.8% U-235)  as fuel, while retaining the MSRE’s significant safety benefits, including full passive safety and atmospheric-pressure operation.  The higher power density, thermal neutron spectrum, and atmospheric pressure operation greatly reduce the cost of the plant, resulting in overnight capital costs on par with coal-fired power plants.

Ultimately, this design has the potential to consume the country’s existing stockpiles of spent nuclear fuel, while safely generating enormous amounts of cheap, carbon-free electricity.

Transatomic Power is  a nuclear reactor design company developing safe and environmentally-friendly power plants that run entirely on nuclear waste.

About the speaker:

Dr. Leslie Dewan graduated from MIT in 2013 with a Ph.D. in nuclear engineering, with a research focus on computational nuclear materials.  She also holds S.B. degrees from MIT in mechanical engineering and nuclear engineering.  Before starting her Ph.D., she worked for a robotics company in Cambridge, MA, where she designed search-and-rescue robots and equipment for in-field identification of biological, chemical, and nuclear weapons.  Leslie has been awarded a Department of Energy Computational Science Graduate Fellowship and an MIT Presidential Fellowship.  She was named a TIME Magazine “30 People Under 30 Changing the World” in December 2013, an MIT Technology Review “Innovator Under 35” in September 2013, and a Forbes “30 Under 30” in Energy in December 2012.

ANS Connecticut Section Speaker Meeting Announcement for April 9th, 2014

Transuranic Uptake at a Commercial Nuclear Power Station

Please join us in welcoming Michael D. Quinn, of WorkPlace Cornerstone Associates (WCA), who will talk about an event at the Bruce Nuclear Power Station that resulted in several hundred worker exposures.

Abstract: During the multi-year refurbishment of Bruce Nuclear Power Station Units 1 and 2, a number of crafts people were engaged in the cutting and grinding of reactor feeder pipes over a several month period.  This evolution resulted in a chronic [and at the time, unknown] release of significant quantities of airborne transuranic (alpha) contamination into the general reactor vault atmosphere.  As a result, several hundred construction trades workers and unit restart staff were exposed to and potentially had an uptake of airborne alpha contamination.

This presentation discusses the precursors to this high consequence/high significance event, the recovery effort, and the lessons learned from the multi-billion dollar refurbishment project.

About the speaker:

Michael Quinn is a Principal of WCA, and has 39 years of experience in the commercial nuclear power industry.  He started his career at CT Yankee Haddam Neck in 1975, earning a SRO License.  Later he worked on the Station Recovery effort while Millstone was on the NRC watch list (1995-1999).  Michael has consulted for the past 14 years to US and Canadian nuclear power stations, nuclear suppliers, and the US NRC, as well as with US DOE operations at Hanford, WIPP, Los Alamos, and Las Vegas.  Dr. Quinn specializes in Human Performance, PI&R, and Safety Culture to facilitate High Reliability performance.

We will be meeting at the Nutmeg Restaurant at 297 South Main Street, East Windsor, CT, April 9th, 2014 at 6PM.  All of the details are provided this flyer:  20140409 Speaker Meeting Announcement

So please save this date on your calendars and RSVP with your dinner selection, affiliation, and contact information by April 4th to Stephen Szarek at 860-731-6313 or szareksw@westinghouse.com.  Dinner choices are:

  • Chicken Francaise
  • Salmon Jacqueline
  • Prime Rib
  • Vegetarian Stir Fry

We hope to see you there!

Presentation Slides from the Speaker Meeting held May 22nd, 2013

Ted Quinn, Past ANS President, spoke at the ANS Connecticut Section Speaker Meeting on May 22nd, 2013.  His presentation, titled “The Challenges of Cyber Security in Nuclear Energy” is available here:

20130522 Presentation Challenges of Cyber Security in Nuclear Energy

This was another successful meeting featuring a very hot topic for the industry.  At Ted’s request, we made him an ANS Connecticut Section member.  This meeting was a great opportunity for current and past I&C Engineers to get reunite and to catch up.  We had a lot of history in the small crowd of 28 people.

Presentation Slides from the Speaker Meeting on February 7th, 2013

Sam Eddinger spoke at the ANS Connecticut Section Speaker Meeting on February 7th, 2013.  His presentation, titled “Fusion: Everything You Always Wanted to Know (but were afraid to ask)” is available here:

20130207 Presentation Fusion Everything you wanted to know

This was a very successful meeting and the topic was well received!  Sam, as many of you know, is a Connecticut Section member.  This meeting was a great opportunity for Sam to gain more experience speaking to a small crowd of about 30 people on a topic of interest to him.  If you or someone you know would like to present at a future ANS Section Meeting, please contact Liz Sundstrom at:  sundstev@westinghouse.com.

We are interested in any topic related to the science, engineering, or social aspects of the atom.
