This UCB report summarizes preliminary design analysis for the 50 MW(t) intermediate heat exchanger (IHX) for the demonstration of hydrogen production with the Next Generation Nuclear Plant (NGNP). Sulfur-iodine (SI) hydrogen production efficiency is maximized when sulfuric acid decomposition is performed at a low pressure (~1 MPa) compared to the NGNP primary coolant pressure (~7 MPa). For a m...

Haloarchaea are salt loving microorganisms isolated from saline environments including ancient salt deposits and rock salt. A few haloarchaeal species have been reported to produce bacteriorhodopsin (BR) which works as a light driven proton pump. A haloarchaeal strain Halostagnicola larsenii IBS (MCC 2956) isolated from commercial Indian black salt (IBS) sample was employed for optimization of ...

To study the influence of earthquakes and engineering disturbances on deformation deeply buried rock masses, shear tests were carried out anchored sandstone marble granite masses under creep fatigue loading, a new model was established to characterize characteristics loading. The curves different lithologies clearly show three stages: attenuation, steady-state creep, accelerated creep. Fatigue ...

Rock salt represents a potential host rock formation for the final disposal of radioactive waste. The interactions between indigenous microorganisms and radionuclides, e.g. uranium, need to be investigated to better predict the influence of microorganisms on the safety assessment of the repository. Hence, the association process of uranium with two microorganisms isolated from rock salt was com...

This paper reports on the pressure dependence of the optical absorption edge of ZnO in the wurtzite and rock-salt phase, up to 14 GPa. Both vapor-phase monocrystals and pulsed-laser-deposition thin films have been investigated. In both types of samples the wurtzite to rocksalt transition is observed at 9.7G0.2 GPa. The absorption tail of the fundamental gap, as measured in monocrystals, exhibit...

Iodine deficiency disorders (IDD) and iron deficiency anemia (IDA) form the major micronutrient deficiencies of public health significance in India; several surveys have indicated that no state in the country is free from IDD and nearly two-thirds of children, women of reproductive age, and adolescent girls across the country are estimated to be suffering from IDA . The control of micronutrient...

buckle folds are common traps for hydrocarbon in several contractional provinces. buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. an important parameter affecting buckle folding of a competent zone above a mobile decol...
