2013/6/3/ · The high temperatures created by the thermophilic process have the benefit of killing harmful pathogens in the compost. When the temperature in the reactor goes above 160 F, thermophilic bacteria become inactive, and the temperature begins to drop. When the material in the reactor has cooled sufficiently, mesophilic bacteria return, and
2021/10/15/ · Here’s the funding problem. In mid August the House Appropriations Committee reported out a bill for 2022 with $1.7 billion in funding for Department of Energy programs but it set zero funding for the versatile test reactor (VTR). The committee report did not provide an explanation for this action. Supporters of the VTR project hope to

2022/5/17/ · The US Department of Energy (DOE) has released the Final Environmental Impact Statement (EIS) for the construction of the Versatile Test Reactor (VTR). The proposed VTR will be a sodium-cooled fast-neutron-spectrum test reactor that will enhance and accelerate research, development, and demonstration of innovative nuclear
2022/8/3/ · DOE's Mission Need Statement for the Versatile Test Reactor (VTR) Project, A Major Acquisition Project embraces the development of a well-instrumented, sodium-cooled, fast-neutron-spectrum test reactor in the 300 megawatt-thermal power level range. The deployment of a sodium-cooled, fast-neutron-spectrum test reactor is
The United States Department of Energy (DOE) has issued a Record of Decision (ROD) for the Final Versatile Test Reactor Environmental Impact Statement (Final VTR EIS) (DOE/EIS-0542). DOE has decided to construct and operate the VTR at Idaho National Laboratory as its preferred alternative and to establish, through modification and
Summary. This Versatile Test Reactor Draft Environmental Impact Statement (VTR EIS; DOE/EIS-0542) evaluates the potential environmental impacts of proposed alternatives for the construction and operation of a new test reactor, as well as associated facilities that are needed for performing post-irradiation evaluation of test articles and managing spent
2007/2/1/ · The composting of organic solid waste, the mixture of fruit and vegetable leftovers enriched with night soil, was investigated in a closed thermally insulated reactor. It was found that 80.9 % of the original substrate biodegraded after 14 days. A mathematical model of the column reactor was proposed where the biodegradation rate of the organic
PYREG's technology turns sawmill residuals such as wood chips and sawdust, into biochar, a versatile and stable form of carbon. The Pyreg technology has been in commercial use for more than 10 years, with over 50 pyrolytic kilns currently deployed globally. The facility operates 24/7 and with precision controls and is utilized by (50)% of

2016/12/1/ · Composting materials were considered as porous substrates that had a temperature of t c and a porosity of γ, was piled to a height of H, had a diameter of d 1, and a surface area of A 1.Temperature of structural layer on the inside was t w 1.Note that both conductive heat transfer between compost and structural layer and convective heat …
2024/6/17/ · When complete, the Versatile Test Reactor will be the only reactor of its kind in the United States and one of a few that exists in the world. Access to those foreign reactors is limited, and protecting intellectual property is tricky. VTR will offer researchers like Simpson, Phongikaroon and Sun more than just a facility to irradiate their
