Comments on ITS: "The integrated TIGER series of electron/photon transport codes - Version 3.0" by J.A. Halbleib et al., "CEPXS/ONELD Version 2.0: a discrete ordinates code packaging for general one-dimensional coupled electron-photon transport" by L.J. Lorence, Jr., and "Recent MCNP developments" by J.S. Bendricks and J.F. Briesmeister

Comments are offered on the three above-titled papers (ibid., vol.39, no.4, Aug. 1992). Regarding the first paper (p.1025-30), it is pointed out that a continuous-energy adjoint Monte Carlo code is available for electron transport, namely, the NOVICE code. The second paper (p.1031-4) gave performance information for a suite of 25 sample problems run on several mainframes and workstations. Performance data are given by the commenter for the same problems run on personal computers. Regarding the third paper (p.1035-40), the commenter points out that the three codes indicated there as available through the Radiation Shielding Information Center have PC versions.<
