The DHS Domestic Nuclear Detection Office (DNDO) is funding a multiyear program of improvements for the MCNPX{sup TM} Monte Carlo radiation-transport code. Additional work is underway for the DTRA Active Interrogation programs. Enhancements contained in the current MCNPX 2.6.0 RSICC release will be presented, including stopped-muon physics, delayed neutron and photon generation and automatic generation of source photons. Preliminary benchmarking comparisons with data taken with a PSI muon beam will be discussed. We will also describe current improvements now underway, including Nuclear Resonance Fluorescence, pulsed sources, and others. We will also describe very new work begun on a Threat-Reduction user inferface, designed to simplify the setup of TR-related calculations, and introduce standards into geometry, sources and backgrounds.
