5. POTENTIAL for HUMAN EXPOSURE 5.1 OVERVIEW White
WHITE PHOSPHORUS 157 5. POTENTIAL FOR HUMAN EXPOSURE 5.1 OVERVIEW White phosphorus can enter the environment from its production, use, accidental spills during loading and unloading for shipment, and accidental spills during transport. Hazardous wastes sites containing white phosphorus can also be a source of phosphorus in the environment. White phosphorus has been found in at least 77 of the 1,430 current or former EPA National Priorities List (NPL) hazardous waste sites (HazDat 1996). However, the number of sites evaluated for white phosphorus is not known. The frequency of these sites within the United States can be seen in Figure 5-l. The persistence of elemental phosphorus in the air is very short due to oxidation to phosphorus oxides and ultimately to phosphorus acids. However, the particulate phosphorus aerosol may be coated with a protective oxide layer that may prevent further oxidation and extend the lifetime of particulate phosphorus in air. Both wet and dry deposition remove unreacted elemental phosphorus and the degradation products from the air. Similarly, elemental phosphorus oxidizes and hydrolyzes in water and in soil. A small amount of elemental phosphorus is lost from soil and water by volatilization. Phosphorus is used as a fumigant in the storage of grain. Because of ease of application, pellets of aluminum or magnesium phosphide are commonly used (Garry et al. 1993). Phosphine, a highly toxic gas, is generated from phosphide. The rate of formation of phosphine (permissible exposure limit [PEL], 0.4 mg/m3) is dependent on the ambient temperature and humidity. Its release is rapid, and it is extremely fatal to the unprotected person (Garry et al. -
Fuel Geometry Options for a Moderated Low-Enriched Uranium Kilowatt-Class Space Nuclear Reactor T ⁎ Leonardo De Holanda Mencarinia,B,Jeffrey C

Kinga, a Nuclear Science and Engineering Program, Colorado School of Mines (CSM), 1500 Illinois St, Hill Hall, 80401 Golden, CO, USA b Subdivisão de Dados Nucleares - Instituto de Estudos Avançados (IEAv), Trevo Coronel Aviador José Alberto Albano do Amarante, n 1, 12228-001 São José dos Campos, SP, Brazil ABSTRACT A LEU-fueled space reactor would avoid the security concerns inherent with Highly Enriched Uranium (HEU) fuel and could be attractive to signatory countries of the Non-Proliferation Treaty (NPT) or commercial interests. The HEU-fueled Kilowatt Reactor Using Stirling Technology (KRUSTY) serves as a basis for a similar reactor fueled with LEU fuel. Based on MCNP6™ neutronics performance estimates, the size of a 5 kWe reactor fueled with 19.75 wt% enriched uranium-10 wt% molybdenum alloy fuel is adjusted to match the excess reactivity of KRUSTY. Then, zirconium hydride moderator is added to the core in four different configurations (a homogeneous fuel/moderator mixture and spherical, disc, and helical fuel geometries) to reduce the mass of uranium required to produce the same excess reactivity, decreasing the size of the reactor. The lowest mass reactor with a given moderator represents a balance between the reflector thickness and core diameter needed to maintain the multiplication factor equal to 1.035, with a H/D ratio of 1.81. -

The Project consisted of hydriding samples of Zr-2.5 Nb pressure tube materials used in CANDU-type and RBMK reactors, the measurement of delayed hydride cracking (DHC) rates under specified conditions, and analysis of hydrogen concentrations. The project was overseen by a supervisory group of experts in the field who provided advice and assistance to the participants as required. All of the research work undertaken as part of the CRP is described in this report, which includes a review of the state of the art in understanding crack propagation by DHC and details of the experimental procedures that produced the most consistent set of DHC rates reported in an international round-robin exercise to this date. All of the participants and many of their co-workers in the laboratories involved in the CRP contributed results and material used in the drafting of this report, which contains compilations of all of the results, their analysis, discussions of their interpretation and conclusions and recommendations for further work. -

Alphabetical Index of Substances and Articles
ALPHABETICAL INDEX OF SUBSTANCES AND ARTICLES - 355 - NOTES TO THE INDEX 1. This index is an alphabetical list of the substances and articles which are listed in numerical order in the Dangerous Goods List in Chapter 3.2. 2. For the purpose of determining the alphabetical order the following information has been ignored even when it forms part of the proper shipping name: numbers; Greek letters; the abbreviations “sec” and “tert”; and the letters “N” (nitrogen), “n” (normal), “o” (ortho) “m” (meta), “p” (para) and “N.O.S.” (not otherwise specified). 3. The name of a substance or article in block capital letters indicates a proper shipping name. 4. The name of a substance or article in block capital letters followed by the word “see” indicates an alternative proper shipping name or part of a proper shipping name (except for PCBs). 5. An entry in lower case letters followed by the word “see” indicates that the entry is not a proper shipping name; it is a synonym. 6. Where an entry is partly in block capital letters and partly in lower case letters, the latter part is considered not to be part of the proper shipping name. 7. A proper shipping name may be used in the singular or plural, as appropriate, for the purposes of documentation and package marking. - 356 - INDEX Name and description Class UN No. Name and description Class UN No. Accumulators, electric, see 4.3 3292 Acid mixture, nitrating acid, see 8 1796 8 2794 8 2795 Acid mixture, spent, nitrating acid, see 8 1826 8 2800 8 3028 Acraldehyde, inhibited, see 6.1 1092 ACETAL 3 1088 -

Zeolites Fit for a Crown: Probing Host-Guest Interactions with Thermogravimetric Methods
Zeolites fit for a crown: probing host-guest interactions with thermogravimetric methods A. Nearchou, R. Castaing, P. R. Raithby and A. Sartbaeva University of Bath, Department of Chemistry, Claverton Down, Bath, BA2 7AY Abstract Every year millions of tons of zeolites are produced, being used as molecular sieves, hydrocracking catalysts, gas-capture materials and for emerging novel applications. There is a demand to synthesize new zeolites with bespoke frameworks, which are tailor-made for a chosen application. Steps towards tailor making zeolites have been listed in the top ten de-sired breakthroughs in 2011 by Science. To achieve these ‘designer zeolites’ it is crucial to fully understand the host-guest interactions between organic templates, used in their preparation, and the zeolitic frameworks, which are still not known. Here we have studied four different zeolites, synthesized with the same organic template, 18-crown-6 ether, which show observable differences in the host-guest interactions. We demonstrate that the framework dominates the decomposition temperature, enthalpy and mechanism. The zeolites show unique decomposition features, emphasizing, for the first time, the difference in how the template and framework interact during synthesis. Introduction Zeolites are crystalline aluminosilicate minerals, characterised by their unique open framework architectures and periodic microporosity. Currently, zeolites have a variety of uses across the chemical sciences, such as catalysts for organic chemistry, molecular sieving, carbon dioxide capture and many other emerging applications.1-4 To this day, zeolites are still the primary catalyst used for petroleum hydrocracking, demonstrating their contemporary robustness that has not been replaced via alternative porous materials.5 As such, there is a desire to prepare new de-signer zeolites which possess bespoke structures to enhance chosen chemical applications.6-10 Current approaches towards designer zeolites make use of organic additives, which direct the crystallisation of a desired topology.
