Why is this work in the frame?
A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.
No Canadian affiliation. An affiliation-only frame — the usual design — would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract
The preparation of plutonium-aluminum alloys by the direct reduction of PuF<sub>3</sub> and PuO<sub>2</sub> with liquid aluminum is described. Experimental fuel rods for the Canadian Heavy Water Reactor (NRX) at Chalk River have been prepared using both processes. PuF<sub>3</sub> is reduced more rapidly at 900°C than at 1100°C with liquid Al, owing to the evolution of gaseous AIF, which is stable at the former temperature. The Pu yield for this process averaged 95% in alloying 337 g of Pu. Alloys for the second fuel rod were prepared by the Al reduction of a pressed Pu0<sub>2</sub>-cryolite mixture at 1100°C, with a Fu yield of 98 per cent The intermetallic compounds PuAl<sub>2</sub>, PuAl<sub>3</sub>, and PuAl<sub>4</sub> have been prepared and examined by X-ray-diffraction methods. PuAl<sub>2</sub> and PuAl<sub>4</sub> are isomorphous with the corresponding U-- Al compounds. PuAl<sub>3</sub> differs slightly from the UAl<sub>3</sub> type structure. Single crystals of PuAl<sub>3</sub> have been prepared, and the X-ray data obtained from them have been used to construct a unit-cell model. (auth)
