It is not clear why tungsten would be a useful material to use in LENR applications. The fact that it does not absorb hydrogen isotopes well seems to suggest that any effects observed would necessarily be surface processes. Is there much information supporting the case that tungsten works for LENR? If it does, I wonder if the fact that it has several relatively long lived isomers is related.
Perhaps more effort needs to be expended in determining whether or not this material actually is useful in LENR. This might shed a lot of light upon the need for surface cracks or other defects to form the NAEs that allow LENR. Also, if tungsten works, then it might suggest that most other heavy metals would work as well.

Hydrogen does not migrate or penetrate into it so many of the Brillouin and W&L theories are difficult to support when a tungsten lattice is used in cold fusion, It also has a high melting point so very high temperatures can be produced before the nano-powder is destroyed. On another note, I would like to see the water and potassium carbide replaced in the high school reactor with lithium hydride as the hydrogen carrier. If such a “mud” of tungsten nano-powder and liquid LiH can be pressurized to 30 bars very high temperature (1200C to 1500C) reaction might be produced. Such high heat can efficiently power a hot CO2 turbine at and efficiency of 60%. We will then enter the realm of industrial quality process heat production.

The formation of these oxides will produce excess heat in the range from 130 to 220 Kcal/mol. This chemically derived source of heat should be eliminated by removing oxygen from the experiment. This change will get the high school experiment closer to what Rossi has done.

You could try posting this there, even in English, it will certainly help them.
