The use of a thermally enhanced grout with a single loop appears to lower borehole resistance by 30%% over neat bentonite grout at standard U-bend separations, despite higher thermal shunting between the legs of the loops.
I was on foot, rounding the last leg of the loop I run whenever I visit this southeastern Pennsylvania countryside I grew up in.
Thermocouples were used to measure the instantaneous local temperature, and a pressure transducer installed in the horizontal leg of the loop measured the flow rate.
Unfortunately, this is not quite right in that there is conductive interference due to the presence of the pipe representing the second leg of the loop.
A particular attention is given to the thermal coupling between the cold and hot leg of the loop with emphasis on overall loop efficiency.
Equation (8), however, is based on a single off-centered pipe conducting to an unobstructed surrounding wall; therefore, one might anticipate that the presence of a second pipe (leg of the loop) would contribute a similar measure, so that the total would simply be half of the single pipe contribution, as suggested by the resistance mesh model given earlier.
Overall, we have shown that this kind of negative feedback loop, consisting of a relatively slow transciptional activation on one leg of the loop, and an inhibition based on fast complex formation on the other, can be designed to respond specifically to a number of different input triggers.
The SXT images reveal an expansion of the X-ray flare kernels along the both legs of the sigmoidal loop toward the loop-top.
The facility has four loops (each one consists of a hot leg, a steam generator, a loop seal, a main circulation pump and a cold leg), a pressurizer connected via two surge line to the hot leg of the loops 2, 4, the emergency-core-cooling system (ECCS) which is provided by an active pump simulating high and low pressure injection systems, and four hydro-accumulators.
