[en] NRC is committed to the periodic publication of licensed fuel facilities inventory difference data, following agency review of the information and completion of any related NRC investigations. Information in this report includes inventory difference data for active fuel fabrication facilities possessing more than one effective kilogram of high enriched uranium, low enriched uranium, plutonium, or uranium-233

[en] The Cross Section Evaluation Working Group (CSEWG) released the ENDF/B-VII.1 library on December 22, 2011. The ENDF/B-VII.1 library is CSEWG's latest recommended evaluated nuclear data file for use in nuclear science and technology applications, and incorporates advances made in the five years since the release of ENDF/B-VII.0, including: many new evaluation in the neutron sublibrary (423 in all and over 190 of these contain covariances), new fission product yields and a greatly improved decay data sublibrary. This summary barely touches on the five years worth of advances present in the ENDF/B-VII.1 library. We expect that these changes will lead to improved integral performance in reactors and other applications. Furthermore, the expansion of covariance data in this release will allow for better uncertainty quantification, reducing design margins and costs. The ENDF library is an ongoing and evolving effort. Currently, the ENDF data community embarking on several parallel efforts to improve library management: (1) The adoption of a continuous integration system to provide evaluators 'instant' feedback on the quality of their evaluations and to provide data users with working 'beta' quality libraries in between major releases. (2) The transition to new hierarchical data format - the Generalized Nuclear Data (GND) format. We expect GND to enable new kinds of evaluated data which cannot be accommodated in the legacy ENDF format. (3) The development of data assimilation and uncertainty propagation techniques to enable the consistent use of integral experimental data in the evaluation process.

[en] The large lepton detector proposed and described in previous workshops was used as a known standard to study how data might be gathered, sorted, and recorded for ISABELLE detectors. The main source of concern is the high singles rate throughout most of the detector, together with the enormous number of individual devices that are running at this rate and must be serviced for each event. A calculation is given of this rate; the result is 1.0 x 10⁷ particles/sec into the detector (at 10³²/cm² sec). In this particular situation the use of charge coupled devices is natural; individual data elements feed continuously into these ''analog delay lines''; yet the data relevant to an occasional event are processed in parallel through a limited number of channels. The general technique seems desirable for many large scale experiments which manage to achieve in some way a reasonable trigger rate

[en] The single arm spectrometer is fully instrumented for high-energy counter/wire chamber experiments. After a brief description of the spectrometer, data are shown for the inclusive reactions a + p → a + X and a + p → b + X, where a = π^+-, K^+-, p, or p-bar, and b is different from a. Considerable attention is devoted to the impact analysis of elastic scattering, although inelastic results are also discussed. Cross sections for a number of interactions are compared. Anticipated experiments are outlined. 16 figures, 2 tables

[en] Lymphyangioleiomyomatosis (LAM) is a rare condition characterized by proliferation of smooth muscle throughout the lung The authors characterize the radiographic morphology of LAM in 10 patients who had pathologically confirmed disease. Chest radiographs and CT scans of 10 female patients with pathologically proved LAM were compared. Correlation was made with pulmonary function tests when available. Chest radiographs revealed normal to increased lung volumes with a diffuse, fine reticular pattern interspersed with cystic lucencies. On CT, the most striking abnormality was a uniform replacement of lung by cysts of varying size from 2 to 30 mm in diameter

[en] The advantages of colliding beams with different energies and various experimental designs for this mode of operation are reviewed for the 400 GeV x 400 GeV ISABELLE. Allowed values of energies, for both bunched and unbunched operation, are compared; allowed lab scattering angles are discussed; and typical maximum momentum asymmetries are tabulated
