Fertile free fuels for plutonium and minor actinides burning in LWRs
… is investigated. Two major categories of inert matrix fuels are studied: composite ceramic fuel particles dispersed in another ceramic matrix (CERCER) and ceramic fuel particles dispersed into a metallic matrix (CERMET). In the category of CERCER, the current world wide research effort has …

ΜΕΛΕΤΗ ΤΗΣ ΧΡΗΣΙΜΟΠΟΙΗΣΗΣ ΤΗΣ ΦΥΣΙΚΗΣ ΡΗΤΙΝΗΣ ΜΑΣΤΙΧΑΣ ΣΑΝ ΒΑΣΗ ΓΙΑ ΤΗΝ ΠΑΡΑΣΚΕΥΗ ΔΙΣΚΙΩΝ ΜΗΤΡΑΣ
… CHIO'S MASTIC WAS USED FOR THE DEVELOPMENT OF A MATRIX TABLET. SOME FACTORS THAT MIGHT AFFECT THE DISSOLUTION RATE FROM THE MATRIX FORMED WERE EXAMINED AS PERCENTAGE OF MASTIC, KIND OF DILUENT, PARTICLE SIZE OF THE DRUG, PH OF THE DISSOLUTION MEDIA, COMPRESSION PRESSURE, SOLUBILITY OF THE DRUG. …

The Effect of Microwave Energy on Sintering
… proliferation and reduce waste volume. The Inert Matrix Fuel (IMF) concept is being considered as an option to reuse the radioactive actinides present in spent nuclear fuel by means of a transmutation process. Due to the volatile nature of these radioactive actinides, it is expected that the …

Supercritical fluid extraction of polychlorinated biphenyls and organochlorine pesticides from mussel tissue (Mytilus edulis)
… vessel. These spike extractions from an inert matrix showed that the chemical integrity of the PCBs was not compromised while some OCPs of the DDT derivative were decomposed to other forms. Preliminary extractions of freeze dried mussel tissue focused on the effect of static extraction …

The Vibrational Spectra of Chlorosubstituted Hydrocarbons
… techniques, including isolation in an inert matrix. The compounds were selected in relation to problems in the understanding of the properties of poly (vinyl chloride).<br/><br/>The physical properties of poly (vinyl chloride) and the capacity to fabricate various products depends on …

Actinide minimization using pressurized water reactors
… pins made of recycled trans-uranics (TRU) in an inert matrix, and are designed to fit in current or future PWRs. Applying appropriate limits on the neutronic and thermal safety parameters, a CONFU-Burndown (CONFU-B) assembly design is shown to attain net TRU destruction in each fuel batch through …

Effects of Xe ion irradiation of ZrN and the migration behaviour of implanted Eu
… has been proposed as a possible candidate for inert matrix for transmutation of long-lived nuclear waste (plutonium and minor actinides) in fast nuclear reactors. In the nuclear reactor environment ZrN will be exposed to di erent irradiations at elevated temperatures. Under these conditions, it …

The use of reduced-moderation light water reactors for transuranic isotope burning in thorium fuel
… it appears that RBWRs are of similar cost to inert matrix incineration in LWRs, and lower cost than RMPWRs and Th- and U-based fast reactor recycle schemes.

Development of Co-processed Plasticized Cellulose Acetate for Sustained Release Matrix Tablets
… a good polymer candidate for sustained release matrix tablets. Sustained release matrix tablets of cellulose acetate can be prepared by direct compression or wet granulation methods. However, previous studies showed that a large amount of CA was required to achieve the desired sustained release …
