Analysis of Neutron Environments in Advanced Reactors Vs. Triga Reactor for In-Core Behavior Studies (2018-04-13)The Fluoride High-Temperature Reactor (FHR) and the Very High-Temperature Reactor (VHTR) are advanced reactor designs in the generation IV class. Advanced reactors operate in more strenuous conditions than older generation ...

-
(2011-08-08)The design of passive heat removal systems is one of the main concerns for the modular Very High Temperature Gas-Cooled Reactors (VHTR) vessel cavity. The Reactor Cavity Cooling System (RCCS) is an important heat removal ...
-
(2009-05-15)The current waste management strategy for spent nuclear fuel (SNF) mandated by the U.S. Congress is the disposal of high-level waste (HLW) in a geological repository at Yucca Mountain. Ongoing efforts on closed-fuel cycle ...
-
(2015-05-26)An existing experimental Reactor Cavity Cooling System using water as the coolant received extensive instrumentation and control upgrades to allow for a thorough investigation into the single-phase flow behavior of the ...
-
(Texas A&M University, 2006-10-30)Minor actinides represent the long-term radiotoxicity of nuclear wastes. As one of their potential incineration options, partitioning and transmutation in fission reactors are seriously considered worldwide. If implemented, ...
-
(Texas A&M University, 2006-10-30)The Very High Temperature Reactor (VHTR) system behavior should be predicted during normal operating conditions and during transient conditions. To predict the VHTR system behavior there is an urgent need for development, ...
-
(2014-08-08)The Very High Temperature Reactor (VHTR) is a Generation IV nuclear reactor that is currently under design. It modifies the current high temperature gas reactor (HTGR) design to have a 1000 ^(0)C coolant outlet. This ...
-
(2011-08-08)The closure of the nuclear fuel cycle is a topic of interest in the sustainability context of nuclear energy. The implication of such closure includes considerations of nuclear waste management. This originates from the ...
-
(2011-10-21)A new high-fidelity integrated system method and analysis approach was developed and implemented for consistent and comprehensive evaluations of advanced fuel cycles leading to minimized Transuranic (TRU) inventories. The ...
-
(2009-05-15)Several alternative strategies are being considered as spent nuclear fuel (SNF) management options. Transuranic nuclides (TRU) are responsible for the SNF long-term radiotoxicity beyond the first 500 years. One of the most ...
-
(2015-12-08)Very High Temperature Reactors (VHTRs) are the future of nuclear reactors. A 1/16th scaled upper plenum of a VHTR was designed and assembled at Texas A&M University (TAMU) in order to study the behavior of flow in the upper ...
-
(2014-12-02)The Reactor Cavity Cooling System (RCCS) is an important passive cooling safety system used to cool the cavity of generation IV Very High Temperature Reactors (VHTR). Texas A&M University built a 1/8 scale experimental ...
-
(2016-08-05)The very high temperature reactor (VHTR) is one of the most promising next generation reactors which will be commercialized in 2030. A loss-of-coolant accident (LOCA) is a major accident scenario in which the primary coolant ...
