Isi,
WRAP is a government entity. Count yourself lucky if a report ever comes out.
True, these are the Brits, but government is government.
I am sub-contractor to the DOE. Over the last 60 or so years, they have loaded several tanks with a slurry. Over the years, naturally the slurry seperated into a solids layer and a liquid layer. Well it is now time to empty the tanks.
Question: how does one re-suspend all of those solids so the tank can be emptied? Well, a mixer pump will probably work, but we needed to know for sure.
So they picked a tank with about 35 feet of liquid and about 6 inches of solids to test, designed, constructed, and installed a variable speed mixer pump with all the controls. They instrumented the he11 out of the tank. Unfortunately, they ran out of money before they could turn the on/off switch to the on position.
When the next budget came out, priorities did not include the mixer pump test, and the mixer pump project was eventually forgotten about.
5 years go by. Someone asks I wonder what happened to the mixer pump test? They then brush the dust off of the project. After a couple of years of fits and starts, and $10,000,000 later, the pump is turned on. Volumes of data were collected. Unfortunately, the budget was spent and no money was left to analyze the data or issue a report, and that is where it sits today. The test was run in 1998.
The good news, is that I have looked at the raw data, and it appears that the pump worked and the solids were re-suspended in that particular tank. The bad news is that none of the equipment has been maintained and it will all have to be replaced before a pump will be able to mix the tank and we actually empty it.
I guess the point I'm trying to make is don't read too much into a late government report. After all, it is the government.
