AbstractAbstract
[en] A new modular multi-purpose furnace has been designed and the prototype constructed. This furnace was a development utilizing more than two decades of experience at the JRC establishment, Karlsruhe, to bring together the possibility of several techniques that normally require separate, expensive facilities. With this new modular device, different functions are provided by exchanging the head of the furnace while leaving the base as a permanent fixture. The processes can be carried out in high vacuum (10-6 Pa) or in the presence of high-purity gases, e.g., argon. The modules developed allow the following processes to be carried out: Arc melting, levitation melting, resistance and radio-frequency heating in a crucible, single-crystal growth by various techniques, and electron-beam heating. The rationale behind the development was to produce a device capable of many functions but at an acceptable cost so as to make the various techniques available to a wide range of research and development institutes. A full description of the apparatus is given, outlining the range of the methods which can be applied to the production of high-purity advanced materials for research purposes

AbstractAbstract
[en] This paper describes work done in order to clarify the formation mechanism of highly toxic micropollutants, such as dioxins and di benzofurans, from electric arc furnaces used in the production of carbon steel from scrap. The study is allowing to derive relationships between the levels of airborne micropollutants and the operational parameters of the production process so that an abatement of pollution could be achieved. By using the European standard method CEN 1948 for dioxin like compounds sampling and measurement, it was possible to determine the characteristic fingerprint of micropollutants emitted by this particular stationary source.

AbstractAbstract
[en] The design and main features of a furnace with a temperature controller and programmer are shown. This system allows to measure the optical absorption spectrum of a sample from room temperature to 400 deg C, in a double beam spectrophotometer Perkin Elmer 350. The sample temperature can be linearly increased at different heating rates between 4 and 38 deg C/min. The temperature ramp can be stopped at any desired point and the sample temperature shall be stabilized in less than one minute. This temperature shall be kept constant within 0.5 deg C for hours. The sample is heated in vacuum. (author)

AbstractAbstract
[en] A simplifier model of arc plasma burning in the radial magnetic field (RMF) is presented by Bujanov et al. To proof experimentally the results of this model the influence of the RMF on the termination of the arc discharge process and on the shape of the radiation density radial distribution of Mg and Sb is investigated. These results, as well as the results acquired from observations of the electric arc burning in the presence of an external radial RMF, give a qualitative confirmation of the model presented by Bujanov et al.

AbstractAbstract
[en] This document describes the Tank Waste Remediation System (TWRS) High-Level Waste (HLW) Program's (hereafter referred to as HLW Program) Melter Candidate Assessment Activity performed in fiscal year (FY) 1994. The mission of the TWRS Program is to store, treat, and immobilize highly radioactive Hanford Site waste (current and future tank waste and encapsulated strontium and cesium isotopic sources) in an environmentally sound, safe, and cost-effective manner. The goal of the HLW Program is to immobilize the HLW fraction of pretreated tank waste into a vitrified product suitable for interim onsite storage and eventual offsite disposal at a geologic repository. Preparation of the encapsulated strontium and cesium isotopic sources for final disposal is also included in the HLW Program. As a result of trade studies performed in 1992 and 1993, processes planned for pretreatment of tank wastes were modified substantially because of increasing estimates of the quantity of high-level and transuranic tank waste remaining after pretreatment. This resulted in substantial increases in needed vitrification plant capacity compared to the capacity of original Hanford Waste Vitrification Plant (HWVP). The required capacity has not been finalized, but is expected to be four to eight times that of the HWVP design. The increased capacity requirements for the HLW vitrification plant's melter prompted the assessment of candidate high-capacity HLW melter technologies to determine the most viable candidates and the required development and testing (D and T) focus required to select the Hanford Site HLW vitrification plant melter system. An assessment process was developed in early 1994. This document describes the assessment team, roles of team members, the phased assessment process and results, resulting recommendations, and the implementation strategy
