[en] Employing an analogy between thermally induced and irradiation induced creep, physical arguments are used first to deduce a one-dimensional constitutive relation for metals under stress in a high temperature and high neutron flux field. This constitutive relation contains modified superposition integrals in which the temperature and flux dependence of the material parameters is included via the use of two reduced time scales; linear elastic, thermal expansion and swelling terms are also included. A systematic development based on thermodynamics, with the stress, temperature increment and defect density increment as independent variables in the Gibbs free energy, is then employed to obtain general three-dimensional memory integrals for strain; the entropy and coupled energy equation are also obtained. Modified superposition integrals similar to those previously obtained by physical argument are then obtained by substituting special functions into the results of the thermodynamic analysis, and the special case of an isotropic stress power law is examined in detail

[en] We present azimuthal angular correlations between charged hadrons and energy deposited in calorimeter towers in central d+Au and minimum bias p+p collisions at √(s_NN)=200 GeV. The charged hadron is measured at mid-rapidities |η|<0.35, and the energy is measured at two separate large rapidity (−3.7<η<−3.1, Au-going direction and 3.1<η<3.9, d-going direction). An enhanced near-side angular correlation across |Δη|> 2.75 is observed in d+Au collisions. Using the event-plane method applied to the Au-going energy distribution, we extract the anisotropy strength v₂ for inclusive charged hadrons at mid-rapidity up to p_T=4.5 GeV/c. We also present the measurement of v₂ for identified π^± and (anti)protons in central d+Au collisions, and observe a mass-ordering pattern similar to that seen in A+A heavy ion collisions. These results are compared with measurements from p+Pb at √(s_NN)=5.02 TeV

[en] A project was initiated to develop an intelligent computer system to assist spill emergency personnel and spill specialists in predicting and analyzing spills as well as their environmental impacts. The system, called SMART, is described, including system objectives, functionality, operational modes, system components and the functionality of each, and data communications between components. SMART is intended to provide the following five general functions: a user-friendly interface, comprehensive inference capability, analytical capability including the ability to predict concentrations and distances of a spill occurrence, knowledge management, convenient input, and multi-form output. The types of knowledge managed in SMART include the heuristic rules needed in the reasoning of spill prediction and impacts on the environment, as well as factual knowledge contained in existing external databases accessed through a database loader. More specifically, the heuristic knowledge comprises such topics as substance behavior, environmental interactions of substances, and the container or transportation vessel. The external databases include a chemical database on fundamental substance characteristics, an environmental database, and a spatial database managed in a geographic information system. 9 refs., 82 figs

[en] We present azimuthal angular correlations measured in central d+Au collisions at √(s_NN)=200 GeV between charged hadrons and energy deposited in calorimeter towers. The charged hadrons are measured at mid-rapidity |η|<0.35, and the energy deposits are measured at forward and backward rapidities (−3.7<η<−3.1, Au-going direction and 3.1<η<3.9, d-going direction). An enhanced near-side angular correlation across |Δη|> 2.75 is observed in d+Au collisions. We also present the correlation between energy deposited in the d-going and Au-going direction. Similar to previous case, an enhancement is also observed in the near-side pairs correlations in most central d+Au collisions which across |Δη|>6.2. Using the event-plane method applied to the Au-going energy distribution, we extract the anisotropy strength v₂ for inclusive charged hadrons at mid-rapidity up to p_T=4.5 GeV/c. We also present the measurement of v₂ for identified π^± and (anti)protons in central d+Au collisions, and observe a mass-ordering pattern similar to that seen in A+A heavy ion collisions. These results are compared with measurements from p+Pb at √(s_NN)=5.02 TeV

[en] This paper presents criticality safety evaluations from an enduser's perspective. Overall issues related to a criticality safety evaluation in an operations support setting are discussed. A work flow process is presented which shows the key steps in conducting an effective criticality evaluation. Finally, a few suggestions are given to assist newcomers to this field

[en] Currently, a website dedicated to enhancing communication and dissemination of criticality safety information is sponsored by the U.S. Department of Energy (DOE) Nuclear Criticality Safety Program (NCSP). This website was developed as part of the DOE response to the Defense Nuclear Facilities Safety Board (DNFSB) Recommendation 97-2, which reflected the need to make criticality safety information available to a wide audience. The website is the focal point for DOE nuclear criticality safety (NCS) activities, resources and references, including hyperlinks to other sites actively involved in the collection and dissemination of criticality safety information. The website is maintained by the Lawrence Livermore National Laboratory (LLNL) under auspices of the NCSP management. One area of the website contains a series of Nuclear Criticality Safety Engineer Training (NCSET) modules. During the past few years, many users worldwide have accessed the NCSET section of the NCSP website and have downloaded the training modules as an aid for their training programs. This trend was remarkable in that it points out a continuing need of the criticality safety community across the globe. It has long been recognized that training of criticality safety professionals is a continuing process involving both knowledge-based training and experience-based operations floor training. As more of the experienced criticality safety professionals reach retirement age, the opportunities for mentoring programs are reduced. It is essential that some method be provided to assist the training of young criticality safety professionals to replenish this limited human expert resource to support on-going and future nuclear operations. The main objective of this paper is to present the features of the NCSP website, including its mission, contents, and most importantly its use for the dissemination of training modules to the criticality safety community. We will discuss lessons learned and several ideas for future development in the area of web-based training for criticality safety professionals. Our effort is intended to stimulate a discussion of ideas and solicit participation in the development of the next generation of a web-based criticality training site that can be used to assist the training of newcomers to this important safety discipline

[en] A bibliographic criticality safety database of over 13,000 records is available on the Internet as part of the U.S. Department of Energy's (DOE) Nuclear Criticality Safety Program (NCSP) website. This database is easy to access via the Internet and gets substantial daily usage. This database and other criticality safety resources are available at ncsp.llnl.gov. The web database has evolved from more than thirty years of effort at Lawrence Livermore National Laboratory (LLNL), beginning with compilations of critical experiment reports and American Nuclear Society Transactions
