LEGS data acquisition facility

Description: The data acquisition facility for the LEGS medium energy photonuclear beam line is composed of an auxiliary crate controller (ACC) acting as a front-end processor, loosely coupled to a time-sharing host computer based on a UNIX-like environment. The ACC services all real-time demands in the CAMAC crate: it responds to LAMs generated by data acquisition modules, to keyboard commands, and it refreshes the graphics display at frequent intervals. The host processor is needed only for printing histo… more

Family number non-conservation induced by the supersymmetric mixing of scalar leptons

Description: The most egregious aspect of (N = 1) supersymmetric theories is that each particle state is accompanied by a 'super-partner', a state with identical quantum numbers save that it differs in spin by one half unit. For the leptons these are scalars and are called ''sleptons'', or scalar leptons. These consist of the charged sleptons (selectron, smuon, stau) and the scalar neutrinos ('sneutrinos'). We examine a model of supersymmetry with soft breaking terms in the electroweak sector. Explicit mixi… more

Development of a computer code for thermal hydraulics of reactors (THOR). Eighth quarterly progress report, July--September 1976. [BWR; PWR]

Description: The purpose of the advanced code development work reported is to construct a computer code for the prediction of thermohydraulic transients in water-cooled nuclear reactor systems. The fundamental formulation of fluid dynamics is to be based on the one-dimensional drift flux model for non-homogeneous, non-equilibrium flows of two-phase mixtures. Particular emphasis is placed on component modeling, automatic prediction of initial steady state conditions, inclusion of one-dimensional transient ne… more

Heavy-ion injection from tandems into an isochronous cyclotron

Description: A design has been realized for the injection of heavy ion beams generated by the BNL 3-stage tandem facility into a proposed isochronous cyclotron. The tandem beams are bunched into +- 1/sup 0/ R.F. phase (less than or equal to 0.5 nsec) in two stages. The beam is then injected into the cyclotron through a valley, past a hill, and into the next valley on to a stripper foil. Only a single steerer is required to make trajectory corrections for the different beams. Two achromats are used to regula… more

Energy conservation and energy decentralization: issues and prospects

Description: Views are presented of the seemingly paradoxical nature and irrationality of the energy system and the decisions that determine its evolution. An economic approach to energy decisions, while widely espoused and generally believed to be the underpinning of our system, appears not to be functioning in very-important areas. The result is enormous waste of economic and intangible resources to produce energy that could be effectively replaced by energy conservation at low costs. This inefficiency in… more

Energy budgets and masonry houses: a preliminary analysis of the comparative energy performance of masonry and wood-frame houses

Description: Energy Performance Standards require the establishment of energy budgets - maximum values of predicted building energy consumption assuming standard building operating conditions. Energy budgets based on minimizing life-cycle-costs to consumers have been computed in earlier reports. The prototype buildings for those studies used wood-frame construction. The energy performance of masonry houses is explored. Theoretical aspects of the modelling of masonry buildings on the DOE-2 program are discus… more

Spectrometer coupled to an electron storage ring for tagging laser backscattered gamma rays

Description: A spectrometer has been designed to momentum analyze electrons, from the 2.5 to 3.0 GeV x-ray storage ring of the National Synchrotron Light Source at Brookhaven National Laboratory, that have lost energy from the production of high energy ..gamma..-rays by Compton scattering of laser light. The electrons detected in the focal plane will provide a tag for the backscattered ..gamma..-rays, determining their energy (to 2.3 MeV), and timing. This design utilizes the fact that, due to kinematics, t… more

OTSG modeling for the analysis of the TMI incident

Description: The IRT code is a reactor plant systems code for the analysis of pressurized water reactor (PWR) transients that is being modified by Brookhaven National Laboratory for the Nuclear Regulatory Commission. A significant modification that has recently been implemented is a model for a once-through steam generator (OTSG) to enable simulation of Babcock and Wilcox (B and W) reactor transients. This paper describes the new OTSG modeling and presents the results of an analysis of the initial phase of … more

BWR/4 loss of feedwater transient analysis

Description: This paper presents an analysis of a series of loss of feedwater (LOF) transients for a typical BWR/4 reactor. These calculations were prompted by the events that occurred during the TMI incident and hence include various assumed failures in the safety/relief valve system and the assumed inoperability of various safety systems. This analysis provides transient results necessary to evaluate the potential for core uncovery and excessive average fuel temperatures which can then be used in the eval… more

Scaling for Tormac fusion reactors

Description: In this paper a set of parameters for a Tormac reactor is developed. The scaling indicates that a Tormac reactor could be constructed with a modest energy output of about 500 megawatts with magnetic fields averaging 20 kG, peak fields of 40 kG, and a plasma radius of about two meters. Wall loading under these conditions can be kept modest. It is further noted that Tormac can be run in a steady state mode. Thus, Tormac makes an economically attractive alternative to tokamak.

Charged-pion spectrometer for the BNL gamma-ray-beam facility

Description: The (..gamma..,..pi../sup +-/) studies planned for the BNL Gamma Ray Beam Facility necessitate the detection of charged pions in the energy range 25 < T/sub pi/ < 150 MeV with a modest resolving power to match the photon beam energy resolution (27 MeV). The solid angle must be as large as possible, and the total path length must be as short as possible to minimize the losses due to pion decay. (The mean lifetime corresponds to L = 4.87 m for T/sub pi/ = 25 MeV). Finally, a means must be provide… more

Analysis of a partial scram event in a typical BWR/4

Description: A study has been made of core thermal-hydraulic conditions and containment suppression pool water temperature following a partial failure to scram in a BWR 4. This was motivated by the occurrence of such an incident in the Browns Ferry Unit 3. If suppression pool temperature should rise too much, the effectiveness of the suppression pool can be impaired. However, the pool temperature in the present case rose no more than 58 degrees (F), which is considered to be acceptable. In this study the tr… more

Statistical cluster analysis and diagnosis of nuclear system level performance

Description: The complexity of individual nuclear power plants and the importance of maintaining reliable and safe operations makes it desirable to complement the deterministic analyses of these plants by corresponding statistical surveys and diagnoses. Based on such investigations, one can then explore, statistically, the anticipation, prevention, and when necessary, the control of such failures and malfunctions. This paper, and the accompanying one by Samanta et al., describe some of the initial steps in … more
