Development of the LICADO coal cleaning process (open access)

Development of the LICADO coal cleaning process

Development of the liquid carbon dioxide process for the cleaning of coal was performed in batch, variable volume (semi-continuous), and continuous tests. Continuous operation at feed rates up to 4.5 kg/hr (10-lb/hr) was achieved with the Continuous System. Coals tested included Upper Freeport, Pittsburgh, Illinois No. 6, and Middle Kittanning seams. Results showed that the ash and pyrite rejections agreed closely with washability data for each coal at the particle size tested (-200 mesh). A 0.91 metric ton (1-ton) per hour Proof-of-Concept Plant was conceptually designed. A 181 metric ton (200 ton) per hour and a 45 metric ton (50 ton) per hour plant were sized sufficiently to estimate costs for economic analyses. The processing costs for the 181 metric ton (200 ton) per hour and 45 metric ton (50 ton) per hour were estimated to be $18.96 per metric ton ($17.20 per ton) and $11.47 per metric ton ($10.40 per ton), respectively for these size plants. The costs for the 45 metric ton per hour plant are lower because it is assumed to be a fines recovery plant which does not require a grinding circuit of complex waste handling system.

Cylinder yard inspections and corrective actions

Inspection of valves on stored uranium hexafluoride (UF{sub 6}) cylinders was initiated at the three diffusion plant sites in Oak Ridge, Tennessee, Paducah, Kentucky, and Portsmouth, Ohio as the result of the discovery of valve defects and evidence of valve leaks at the Oak Ridge K-25 plant. The coordinated inspection culminated in the identification of additional factors related to long-term safe storage of UF{sub 6}, and plans for correction of such deficiencies are presently being developed and implemented. These corrective actions supplement existing programs aimed at assurance of safe storage as summarized in the report.

Impulse gage development for the 100-200 ktap range (open access)

Impulse gage development for the 100-200 ktap range

Special effects underground test (UGT) material response and source diagnostics data require impulse gages that can be used in the 50--150 ktap range and have equilibrated from electrical and mechanical noise sources within 0.001 s. Such gages were designed, analyzed, and tested under this program. One- and two-dimensional stress propagation calculations were performed and predictions were developed for deformation of the gage specimen cup. These predictions were conservative when compared to gas gun test results. The response of the gage will equilibrate within 5% to its final value within 300 {mu}sec. The impulse delivered to the gages for these tests exceeded 250 ktap. The code and experimental results provides a basis for confidence in the operability of the gage in an actual UGT environment.

Damage parameters for candidate Fusion Materials Irradiation Test facilities (open access)

Damage parameters for candidate Fusion Materials Irradiation Test facilities

A comparison was made of damage parameters for carbon, iron, and molybdenum irradiated in spectra for d-Li, spallation, and beam-plasma (d-t) neutron sources and a reference DEMO first wall spectrum. The transmutation results emphasize the need to define the neutron spectra at low energies; only the DEMO spectrum was so defined. The spallation spectra were also poorly defined at high neuron energies; they were too soft to produce the desired gas production rates. The treatments of neutron-induced displacement reactions were limited to below 20 MeV and transmutation reactions to below 50 MeV by the limited availability of calculational tools. Recommendations are given for further work to be performed under an international working group. 12 refs., 6 figs., 3 tabs.

Damage parameter comparison for candidate intense neutron test facilities for fusion materials (open access)

Damage parameter comparison for candidate intense neutron test facilities for fusion materials

It is recognized worldwide that an intense source of fusion energy neutrons is needed to evaluate candidate fusion materials. At an International Energy Agency (IEA) workshop held in San Diego in February 1989, an Evaluation Panel recommended that three neutron source concepts be developed further. The panel also recommended that further comparisons were needed of their irradiation environments. In this paper, a comparison is made of damage parameters for beryllium, carbon, silicon, vanadium, iron, copper, molybdenum, and tungsten irradiated in spectra characteristic of di-Li, spallation, and beam-plasma (d-t) neutron sources and in a reference DEMO first wall spectrum. The treatment of neutron-induced displacement reactions is confined to the region below 20 MeV and transmutation reactions to below 50 MeV by the limited availability of calculational tools. The spallation spectrum is relatively soft; less than 2% of the neutrons are above 50 MeV. The transmutation results emphasize the need to define the neutron spectra at low, as well as high, energies; only the DEMO spectrum is adequate in this respect. Recommendations are given for further work to be performed under an international working group. 12 refs., 2 figs., 3 tabs.
