Natural circulation as a mode of heat removal is being considered as a prominent passive feature in the innovative nuclear reactor designs, particularly in boiling-water-reactors, due to its simplicity and economy.
So far, there aren't many sources to choose from in terms of filling out a full profile, and I think Apple could do some work in terms of making it easier for users to drill down to individual day totals from their activity history, but this is a nice, passive feature that Apple has managed to make power efficient and accurate with the new M8.
These data confirm that the regulation of alternative promoters is a targeted rather than passive feature.
To acquire a passive safety feature, the reactor was mainly improved with regard to graphite oxidation resistance.
We applied a passive cooling feature to both normal and abnormal operations of a small modular reactor (SMR) without external power sources and reactor coolant pumps.
SNCLFR-100, a 100 MWth lead-cooled small modular reactor with a passive cooling feature to both normal and abnormal operations, was proposed by University of Science and Technology of China (USTC).
Taken together, these data suggest that anion channel activation is not a passive secondary feature of plant responses to stress, but a driver of these processes.
This model allows an assessment of a combination of passive features such as solar chimney and wind induced earth air tunnel for both natural and hybrid ventilation systems at the design stage [8].
In addition to this passive feature, several innovative passive safety systems have been incorporated in the design, for decay heat removal under shut down condition and mitigation of postulated accident conditions.
This was done by developing a mathematical model to incorporate passive features into a multi-zone ventilation model incorporating a simple thermal model using COMIS-TRNSYS software (Madison, WI, USA).
