[en] Decommissioning projects are characterized by several risks, long schedule and cost estimates that lie in the range of hundreds of billions of dollars. In many countries, decommissioning projects are even more significant than the nuclear new build. Despite this extremely high relevance there is a huge gap in the literature concerning the benchmarking of these projects. The ultimate goal of the research is to understand communalities between successful projects and unsuccessful ones to draft guideline for the project management. The research methodology presented here is based on a structured process to review the cases and to spot “cross-case” patterns. These “patterns” will then be generalized to generate theoretical propositions.

[en] Eight of the papers to be considered in Session K are directly concerned, at least in part, with the Pool Critical Assembly (P.C.A.) benchmark at Oak Ridge. The remaining seven papers in this session, the subject of this review, are concerned with a variety of topics related to the general theme of Benchmarks and will be considered individually

[en] The report describes experimental benchmark problems as conducted at the SPERT III. The goal of the report is to provide sufficient experimental details to enable simulation of the experiments. It should be used in conjunction with the companion report, SPERT III E Core: Facility Specification. (author)

[en] As part of the effort to increase the number of ions per bunch in RHIC, a new scheme for RF capture of EBIS ions in Booster at injection has been developed. The scheme was proposed by M. Blaskiewicz and J.M. Brennan. It employs a barrier bucket to hold a half turn of beam in place during capture into two adjacent harmonic 4 buckets. After acceleration, this allows for 8 transfers of 2 bunches from Booster into 16 buckets on the AGS injection porch. During the Fall of 2011 the necessary hardware was developed and implemented by the RF and Controls groups. The scheme is presently being commissioned by K.L. Zeno with Au32+ ions from EBIS. In this note we carry out simulations of the RF capture. These are meant to serve as benchmarks for what can be achieved in practice. They also allow for an estimate of the longitudinal emittance of the bunches on the AGS injection porch.

[en] The assessment of emerging nuclear fast reactor designs and concepts viability requires a combination of foresight methods. A mechanism that allows for the comparison and quantification of the possibility of being a proven technology in the future, β for the existing fast reactor designs and concepts is proposed as one of the quantitative foresight method. The methodology starts with the identification at the national or regional level, of the factors that would affect β. The factors are then categorized into several groups; economic, social and technology elements. Each of the elements is proposed to be mathematically modelled before all of the elemental models can be combined. Once the overall β model is obtained, the β_m_i_n is determined to benchmark the acceptance as a candidate design or concept. The β values for all the available designs and concepts are then determined and compared with the β_m_i_n, resulting in a list of candidate designs that possess the β value that is larger than the β_m_i_n. The proposed methodology can also be applied to purposes other than technological foresight

[en] NaNet is an FPGA-based PCIe X8 Gen2 NIC supporting 1/10 GbE links and the custom 34 Gbps APElink channel. The design has GPUDirect RDMA capabilities and features a network stack protocol offloading module, making it suitable for building low-latency, real-time GPU-based computing systems. We provide a detailed description of the NaNet hardware modular architecture. Benchmarks for latency and bandwidth for GbE and APElink channels are presented, followed by a performance analysis on the case study of the GPU-based low level trigger for the RICH detector in the NA62 CERN experiment, using either the NaNet GbE and APElink channels. Finally, we give an outline of project future activities

[en] In this work we report on the development of a new method for computing mi- and high-Z NLTE opacities. A study has been performed using this method to assess the EOS and opacity sensitivities to the radiation field for both single species Au and multi-species SnNb and U₃Au plasma cocktails with an emphasis on moderately to highly ionized systems. Developed as a benchmark tool, this capability will be used to assess both current and future in-line NLTE opacity capabilities.
