FILMS OF RADIOCHROMIC DOSIMETRY MATERIAL COUPLED WITH FILTERS PROVIDE BOTH DOSE AND SPECTRAL INFORMATION ON NUCLEAR TESTS, A SUBSTANTIAL MONITORING CAPABILITY. THE DIAGNOSTIC DEVICES, HOWEVER, OCCUPY SUBSTANTIAL VOLUME; THE MATERIALS BLEACH DUE TO RADIATION DAMAGE AND ARE PRONE TO DYE MIGRATION. ALL CONSTITUTE SIGNIFICANT LIMITATIONS. A FIBER OPTIC DOSIMETER IS PROPOSED FOR UNDERGROUND NUCLEAR TES ...

The Ktech Team proposes a feasibility study of a fuel/air driven flux compression power unit (FCPU) for electric guns. Through variations of inductance gradients and through changes in scale, the proposed technology will be applicable to both electrothermal/chemical and electromagnetic guns. In the Phase 1 effort, we develop simulation models to predict the performance of the flux compression po ...

One of the most challenging problems in adding realism to the battlefield environment in DIS Exercises is treatment of the dynamic physical materials and processes resulting from battlefield munitions (i.e., battlefield smoke and dust, blast and shock damage to buildings, cratering of terrain and roadways, etc.). Currently, there is no alteration of terrain and cultural features due to nuclear we ...

MISSION RESEARCH CORPORATION (MRC) PROPOSES TO BUILD HF-NEPS, AN HF CHANNEL SIMULATOR FOR BENCH-TOP TESTING OF HF TRANSCEIVERS. THE SIMULATOR WOULD DISTORT AND DELAY ANALOG HF SIGNALS AS IF THESE HAD PASSED THROUGH IONOSPHERIC REGIONS DISTURBED BY HIGH ALTITUDE NUCLEAR EXPLOSIONS. THE FREQUENCY SELECTIVE HF CHANNEL MODEL UNDERLYING THIS HARDWARE SIMULATOR WILL ACCOMMODATE THE HF CHANNEL SPECIFICAT ...

OPTICAL EFFECTS OF NUCLEAR EXPLOSIONS, PARTICULARLY MULTIBURST INTERACTIONS AND INFRARED STRUCTURE DUE TO FIREBALL TURBULENCE, ARE OF CURRENT INTEREST. THE BEAU GESTE EXPERIMENT DATA BASE IS UNIQUE IN INCLUDING HOTWIRE ANEMOMETRY, IR VIDEO RECORD, AND VISIBLE LIGHT PHOTOGRAPHS FOR SINGLE AND MULTIPLE DETONATIONS. PRI PROPOSES TO DIGITIZE SELECTED IR, VISIBLE AND ANEMOMETRY DATA, OBTAIN POWER SPECT ...

Alameda Applied Sciences Corporation (AASC) proposes to develop a new type of interferometer that is compact and portable and can be used to make in-situ measurements of gases and plasmas. This interferometer uses polarization maintaining optical fibers and diode lasers to duplicate the capabilities of existing Mach-Zender interferometers that use dicrete optical elements such as mirrors, lenses ...

A SIMPLIFIED RECONNAISSANCE-TYPE TEST IS PROPOSED THAT UTILIZES THE TECHNIQUES OF TRACER GAS VENTILATION TESTING TO QUANTIFY THE UNFILTERED AIR INLEAKAGE INTO AN OPERATING NUCLEAR POWER PLANT CONTROL ROOM. THE TEST WILL BE DEVELOPED TO ENCOMPASS THE FIVE BASIC TYPES OF CONTROL ROOM EMERGENCY VENTILATION SYSTEMS. A THOROUGH ERROR ANALYSIS WILL ALSO BE UNDERTAKEN. A DETAILED TESTING PROTOCOL SUITABL ...

THE ADVANCE OF TECHNOLOGIES MAY MAKE DEFENSE AGAINST BALLISTIC MISSLES TECHNICALLY AND ECONOMICALLY FEASIBLE. A NATIONAL POLICY DEBATE HAS BEGUN ON THE DESIRABILITY OF MAKING A TRANSITION FROM STRATEGIC DETERRANCE TO STRATEGIC DEFENSE. THE DEBATE IS AT PRESENT HIGHLY CONFUSING AND UNSTRUCTURED, SINCE THE VARIOUS ARGUMENTS FOR AND AGAINST THAT TRANSITION ARE BASED ON DIFFERING ASSUMPTIONS, OFTEN TA ...

CURRENT ACTIVITY WITHIN THE NRC AND THE NUCLEAR INDUSTRY SEEKS TO EXPLOIT THE BENEFITS OF PRA IN RISK-BASED APPROACHES TO RELIEVE REGULATORY BURDEN ON THE ECONOMICALLY THREATENED NUCLEAR POWER PLANTS. THE ACCIDENT PREVENTION GROUP HAS BEEN DEVELOPING THE CONCEPT OF AN INTEGRATED RISK MANAGEMENT PROGRAM (IRMP) TOWARD SUCH GOALS. A KEY ELEMENT OF AN IRMP IS AN "OPERATIONAL RISK MODEL" OF THE NPP THA ...
