GE-ANPD Computer Program 0641 may be used to evaluate the radioisotope volume diffusion current at the surface of a bare slab, in a parallel array of slabs, in each of which the fission point density is uniform. These slabs are assumed to be separated by a fluid layer. The current, (J) the time integral of J, and the space integral of the radioisotope concentration are evaluated as functions of time for each of the isotopes in a four-member decay scheme. The effect of fission fragment recoil escape into the fluid layer and re-entry build- up due to fragments which traverse this layer is accounted for in the description of the direct fission source term for each isotope. Program 0641 can be used on either the IBM 704 or the IBM 7090 computer. (auth)
