SuperCritical Water Oxidation (SCWO) process is investigated at the Institut of Technical Chemistry, ITC-CPV. The objectives were to determine destruction efficiencies of model compounds and industrial waste effluents and to study the feasability of the SCWO process. Two continuous SCWO bench scale plants are operated: a pipe reactor and a transpiring wall reactor system (design data: T = 630 °...
The product of the biological sulphate reduction is sulphide. High concentrations of molecular H2S (g) can be inhibitory for microbial activity, especially at a reactor pH of 6 to 7. This paper focuses on the effect of high sulphide concentrations on the sulphate reduction rates. The results of three investigations operating a continuous reactor, a column reactor and batchtest reactors have sho...
The Slovenian 250 kW TRIGA Mark II reactor operated by the Jožef Stefan Institute (JSI) has continuously operated since 1966. Since its commissioning it has played an important role in developing nuclear technology and safety culture in Slovenia. During the years the reactor has been utilized for training, research and isotope production. Education and training activities comprise regular exper...
This study investigated the performance and stability of an anaerobic baffled filter reactor in the treatment of algae-laden water from Taihu Lake at several organic loading rates. The study also evaluated the capability of soft filler to train granule sludge and improve the anaerobic environment and sludge activity in the anaerobic baffled reactor (ABR), thereby enhancing the treatment efficie...
An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...
Among the anaerobic systems applied for the treatment of paper industry effluents, the IC (Internal Circulation) reactor is gaining a lot of interest. The reactor combines good biomass retention at the outlet with excellent mixing characteristics in the lower part of the reactor. This leads to smaller reactor volumes and less space requirements. Three examples of IC reactors at various recycle ...
In this work, the suitability of several techniques for monitoring a reverse-flow reactor system are studied. Reverse reactor systems are operated by periodically reversing the direction of the flow inside the reactor [1],[2]. One benefit of a reverse-flow configuration is that, for exothermic reactions, the system exhibit a heat-trap effect [3] where the temperature profile across the reactor ...
REACTOR is an expert system under development at EG&G Idaho, Inc., that will assist operators in the diagnosis and treatment of nuclear reactor accidents. This paper covers the background of the nuclear industry and why expert system technology may prove valuable in the reactor control room. Some of the basic features of the REACTOR system are discussed, and future plans for validation and eval...
Carbonation of magnesiumand calcium-silicate minerals to form their respective carbonates is one method to sequester carbon dioxide. Process development studies have identified reactor design as a key component affecting both the capital and operating costs of ex-situ mineral sequestration. Results from mineral carbonation studies conducted in a batch autoclave were utilized to design and const...
The objective of the revised Reactor Oversight Process is to monitor licensee performance in the areas of reactor safety, radiation safety, and security. This paper describes the NRC’s revised Reactor Oversight Process and how it is used to assess licensee performance against stated objectives in seven areas (or cornerstones) of plant operations. One of the seven cornerstones of the Reactor Ove...
