Waste Management Concepts for Special Radioactive

As these "problematic" wastes were not properly addressed in the past, some of them failed to meet the acceptance criteria for processing or final disposal. The current RD approach suggests a detailed characterization of every waste stream for development of an individual approach for treatment for waste minimization, waste encapsulation technology and safe disposal.

Gratomic Announces Commissioning of Aukam Processing

2021/3/29Gratomic is in the process of solidifying its plans for micronization and spheronization of its clean Aukam graphite. This significant milestone is a small, additional step in the Company's proposed eco-friendly processing cycle and is intended to allow it to meet

New Tech Disrupts Traditional Aseptic Processing

There have been recent innovations around isolator and restricted access barrier system (RABS) technology. At the 2018 PDA Annual Meeting, session B2: Aseptic Processing Isolators will address these technologies on Tuesday, March 20 at 1:45 p.m. Below are two articles from each of the speakers.

Examination of Surface Deposits on Oldbury Reactor Core

Previous research on irradiated PGA graphite has shown that there is a difference in Raman spectra obtained from PGA, irradiated graphite and surface deposits [8]. In this work Raman spectroscopy was evaluated as a method of differentiating between these three types of carbon samples to allow rapid determination of the sample type in subsequent analysis.

Insights into thermal reduction of the oxidized graphite

1. Introduction In the nuclear industry, graphite has been widely utilized in HTGR where graphite and carbon materials are used for in-core structural components, such as fuel blocks, reflectors, core support structures and a fuel element matrix material. 1–4 Hence, the decommissioning of HTGR will produce a large amount of irradiated graphite waste.

Guide to Irradiation and Sterilization Validation of

Products irradiated to such SALs are still sterile but have higher probabilities of nonsterility and may not meet standards for validated sterile claims as specified in industry standards for sterilization of health care products. The gamma irradiation process uses

An Introduction to Nuclear Waste Immobilisation

Drawing on the authors' extensive experience in the processing and disposal of waste, An Introduction to Nuclear Waste Immobilisation, Second Edition examines the gamut of nuclear waste issues from the natural level of radionuclides in the environment to geological disposal of

Graphite

There are currently several other graphite projects being developed around the world to help meet the anticipated demand - most notably in Eastern Africa. However, the combination of world class natural purity, low mining and processing costs, and comparatively low environmental impact places Seruwila graphite in a strong position to capture market share (see Competition ).

Harper International Successfully Completes Virtual

Over the years, Harper has been a continued innovator of thermal processing solutions for the materials industry, including the first furnace to process nuclear fuels in the 1940s and the first commercial graphite-element furnace-equipment capable of operating at

Status report on the disposal of radioactive wastes

2021/4/18The options include whole-block disposal, disposal with removal of graphite (either mechanically or by burning), and reprocessing of spent fuel to separate the fuel and fission products. The report summarizes what is known about the options without extensively projecting or analyzing actual performance of waste forms in a repository.

Updating irradiated graphite disposal

This work addresses the particular waste stream of irradiated graphite, mostly derived from reactor moderators and amounting to more than 250,000 tonnes world-wide. Use may be made of its unique chemical and physical properties to consider possible processing and disposal options outside the normal simple classifications and repository options for mixed low or intermediate-level wastes.
