Wrapper material

Existence of a thin layer of water around the cartridges can also prevent the interruption of detonation. The water layer perhaps acts as a hard wrapper material Ref H. Fukuda, KogyoKayakuKySkaishi 22, 71-82(1961) CA 59, 6189(1963)... [Pg.347]

This was enabled by the utilization of the advanced fuel cladding and wrapper materials resistant to a damage dose as high as 100 dpa. [Pg.104]

The radiation-resistant fuel structural materials, i.e. the 311-450 steel as wrapper material and the HC-68 steel as cladding material, are used. [Pg.104]

Post-irradiation examinations of cladding and wrapper materials... [Pg.77]

Creep tests of the base wrapper material were performed at 550 and 600 C. The results of base material, of welds and irradiated material are in the same scatter band. [Pg.78]

The impact tests of the wrapper material after irradiation showed a small decrease of the upper shelf energy. The DBTT (Ductile to Brittle Transition Temperature) was hardly influenced. [Pg.78]

Summarizing, the martensitic 10% Cr-steel showed good mechanical properties as wrapper material, especially in the regions of high doses. The mechanical properties and the fracture behavior will be discussed by the microstructural changes. [Pg.78]

The causes and conditions of general achievements and setbacks in reactor and liquid metal coolant technologies are presented in the FRDB, e.g. those determining breeding characteristics (core geometry, fuel enrichment and fissile isotope content, volume fractions, intrinsic limits and smeared density of fuel and blanket pellet, etc), and the fuel bumup limits (chemical composition, fuel fabrication technology, neutron flux, dimensions, cladding and wrapper material, etc.)...

In the field of AGT 1, the main objective is to validate the final choice of clad and wrapper materials, based on the assessment of parameters such as neutron-induced swelling, high temperature creep and evolution of mechanical properties. Three classes of alloys are... [Pg.406]

According to design studies in Europe and Japan, the fuel bum-up target for commercial fast reactors should be 200,000 MWd/t and the irradiation dose target for cladding and wrapper materials should not be less than 180 dpa. The relevant experience obtained so far from experimental fast reactors is shown in Table 9.10. [Pg.521]

Finally, for the traveling wave reactor (TWR) concept, HT9 steel was chosen as cladding and wrapper material [29]. In this particular case, the requirements on in-core materials are particularly demanding, since the peak dose on the TWR cladding is evaluated to be in the range 500—600 dpa, i.e., much more than the maximum irradiation dose ever achieved in a neutron irradiation experiment of FM steels.

If a sample is prepared correctly, no vapors of accelerants will be lost once it is placed in an adequate container and properly sealed ( 3). Many good specimens are handled subsequent to recovery in such a way that the flammable accelerants present are lost. Upon reaching the forensic chemist, he either has very little accelerant to recover and examine, or he has none. Porous containers and wrappers such as paper bags, bundles of newspapers and cardboard boxes are frequently substituted for suitable airtight containers. In these instances, volatile materials are invariably lost through evaporation. [Pg.112]

The most important application area of HDPE is the production of containers and injection molded articles. Bottles for detergents, gasoline cans and heating oil tanks are some examples. The most common use of HDPE for injection molded articles is for the production of storage and distribution containers, like buckets and bottle cases. However, processing into films and pipes has become increasingly more common. Films made out of HDPE possess high fat resistance (as wrappers for meat) and have better aroma barrier properties compared to lower density PE materials. [Pg.25]

Composition They consist of an absorbent carbonaceous material in a canvas wrapper soaked with liquid oxygen. [Pg.94]
