The 11st, Year 2019 Colloquium 
"Accident Tolerant Fuel?"
Lecturer: Ronald G. Ballinger
Affiliation: Dept. of Nuclear Science and Engineering, MIT
Date: 2019.10.10(Thu) 17:00-18:30
Location: North Bldg. #2, 6th Floor Meeting Room
Language: English
Outline: The Fukushima accident has prompted the development of several advanced LWR fuel designs. The goal of these “Accident Tolerant Fuel” (ATF) designs is to provide improved robustness during a beyond design basis accident. In the US accident in question is a station blackout (SBO) event. However, the Fukushima accident has also resulted in mandatory plant modifications to mitigate against a SBO. Plant modifications-termed Diverse and Flexible Coping Strategies (FLEX) have been implemented at all US plants. In this talk the various ATF designs will be discussed considering : (1) margin gained during an SBO, (2) margin gained during abnormal and accident events, and (3) cost/benefit considerations related to implementation.

The 7th, Year 2019 Colloquium 
"Nuclear Structure Studies based on Total Absorption Spectroscopy"
Lecturer: Prof. Alejandro Algora
Affiliation: Instituto de Fisica Corpuscular (Valencia, Spain) and RIKEN Nishina Center (Wako, Japan))
Date: 2019.8.6(Tue) 15:00-16:30
Location: North Bldg. #2, 6th Floor Meeting Room
Language: English
Outline: Total absorption spectroscopy can provide beta decay data free from the systematic error called the Pandemonium effect. Applying this technique can be relevant for nuclear structure studies that require a proper determination of the distribution of the beta strength in the daughter nucleus. In this presentation, the study of the beta decay of the very exotic 100Sn decay at the RIBF facility at RIKEN will be presented. Additionally the study of the beta decay of 186Hg will also be shown.

The 11st, H30 Colloquium 
"Impact of pear-shaped fission fragments on mass-asymmetric fission"
Lecturer: Guillaume Scamps
Affiliation: Center for Computational Sciences, University of Tsukuba
Date: 2018.11.5(Mon) 13:00-14:30
Location: North Bldg. #2, 6th Floor Meeting Room
Language: English
Outline: The fission of most of the actinide results in an asymmetric splitting with a heavy fragment with a charge around Z=54. We used the Time-dependent Hartree-Fock (TDHF) with the BCS approximation to simulate the fission of 7 actinides nuclei. For all of them, we found the correct charge splitting with a heavy fragment produced predominantly with 52-56 protons. Using the nucleon localisation function, we show that the pre-fragments acquired quickly a strong octupole shape.

The 5th, H30 Colloquium 
"Mathematical modelling of mass transfer during liquid-liquid plug flow in small scale channels"
Lecturer: Miguel Arnaldo Pineda Rodriguez

Outline: Analysis of radioactive nuclides has been essential for realizing efficient and safe treatment and disposal of radioactive wastes from nuclear power plants. Herein, I will discuss two mathematical modelling frameworks to study the extraction of radionuclides in two-phase systems during plug flow in a single microchannel. Possible extensions of these mathematical approaches are also discussed for multiple separations of individual metals contained in the waste.
