Book Description
Previous reports on the chlorination of plutonium dioxide describe numerous small-scale experiments and a few fair-sized batch preparations. The chemistry of chlorination by numerous reagents is covered, but no process had received sufficient study for large-scale preparation of anhydrous plutonium trichloride. The literature search revealed no extensive studies on chlorination rates, exhaust gas filtering, atmospheric requirements, reactor materials, etc. A program was undertaken to select a chlorination process, to develop the necessary information for defining operating conditions and equipment specifications, and then to demonstrate the operation of the process.

Book Description
An automatic recording thermobalance for studying the chlorination of plutonium dioxide with phosgene is described. The highly toxic and corrosive nature of these materials imposed restrictions on the construction and operation of the thermobalance. The instrument operates on the deflection balance principle in which the extension of a precision quartz helix spring is measured by a linear variable differential transformer. Experimental results from the gas- solid reaction between phosgene and plutonium dioxide are discussed. (auth).

Book Description
Batches of plutonium dioxide were chlorinated by reaction with phosgene or carbon tetrachloride. Plutonium trichloride prepared by either method can be reduced to the metal in an hermetically sealed bomb by reaction with calcium. It has been demonstrated that a method for the reduction of plutonium trichloride to the metal without the use of a booster can be developed. Soluble plutonium in slag and crucible waste can be precipitated as the hydroxide and washed essentially free of chloride contamination. The concentrated nitric acid solution from dissolution of plutonium hydroxide and other solids contains less than 75 ppm chloride. Of the materials tested the Hastelloy alloys A, B, and C were found to be the most resistant to phosgene corrosion. The corrosion of these alloys was found to lie between 1 x 10−4 and 2 x 10−4 in. per month at 300 deg C and between 1 x 10−3 in. per month at 450 deg C. The logarithm of the corrosion rate plotted as a function of the temperature appears to be linear over the temperature range of 300 to 550 deg C. Above 550 deg C the corrosion rate of all materials tested is excessive. (auth).
