A blanket concept made of SiCf/SiC composite and utilizing Flibe as coolant and tritium breeder has been developed and integrated with the magnetic intervention system. To achieve tritium self-sufficiency, a 1 cm thick Be insert is utilized in the first wall coolant channel. All magnet, vacuum vessel, and personnel shielding requirements can be satisfied. The nuclear performance parameters of t...

Neutronics-processing interface parameters have large impacts on the neutron economy and transmutation performance of an aqueousbased Accelerator Transmutation of Waste (ATW) system. A detailed assessment of the interdependence of these blanket neutronic and chemical processing parameters has been performed. Neutronic performance analyses requi’re that neutron transport calculations for the A’T...

Heat transfer in closed channel flows of molten salts (MS)s, such as FLiBe or FLiNaBe, has been considered under specific reactor conditions. MHD effects have been accessed for two blanket concepts: self-cooled MS blanket, and dual-coolant MS blanket. The effect of heat transfer degradation due to turbulence reduction by a magnetic field in the First Wall channels of the selfcooled blanket was ...

Detailed three-dimensional (3-D) neutronics calculations have been performed for the dual coolant molten salt blanket designs. The model includes the detailed heterogeneous geometrical arrangement of the inboard (IB) and outboard (OB) blanket sectors. The total tritium breeding ratio (TBR) is ~1.07. The 1-D calculations tend to overestimate nuclear heating in the blanket by ~8% resulting in ove...

Detailed activation analyses have been performed for the different blanket design options considered in the ITER blanket option trade-off study. The options considered included a selfcooled Li/V option, a helium cooled Li/V option, and a water cooled 316 SS non-breeding shield option. A vacuum vessel made of double wall inconel 625 and water cooled 316 SS balls is used with all options. The He-...

PRIMARY SOURCES A search of MEDLINE using ‘weighted blanket’ OR ‘weighted vest’ OR ‘pressure vest’ AND ‘autistic spectrum disorder’ yielded 11 results, of which 0 were relevant. A search of MEDLINE using ‘weighted blanket’ OR ‘weighted vest’ OR ‘pressure vest’ AND ‘sleep’ yielded 0 results. A search of CINAHL using ‘weighted blanket’ OR “weighted vest’ OR ‘pressure vest’ AND ‘autistic spectrum ...

UNLABELLED Perioperative hypothermia poses a challenge because of its deleterious effects on patient recovery. The current practice of applying two cotton blankets on patients during surgery is thought to be less ideal than using reflective insulation or forced-air warming. We studied 300 patients who underwent unilateral total knee replacement and were randomized equally to three groups: (a) t...

Blanket bog occupies approximately 6 % of the area of the UK today. The Holocene expansion of this hyperoceanic biome has previously been explained as a consequence of Neolithic forest clearance. However, the present distribution of blanket bog in Great Britain can be predicted accurately with a simple model (PeatStash) based on summer temperature and moisture index thresholds, and the same mod...
