No. 409 January 1999

A politician thinks of the next election; a statesman, of the next generation.--J. F. Clarke



Center? Commission?

Habit is powerful. I must apologize for referring to NRC as the U.S. Nuclear Regulatory Center instead of Commission. The NRC has not changed its name, only the Center that will handle its software distribution. It would seem that not only did I type what my eye has been trained to see, but my several proofreaders overlooked it as well until the hard copy of the newsletter was mailed. Though the hardcopy could not be corrected, the newsletter posted to the web is correct, at least with respect to the NRC.

Alice F. Rice

NRC Codes Made Available

U.S. Nuclear Regulatory Commission (NRC) software packages were transferred from the ESTSC to RSICC, and several were incorporated into the RSICC computer code collection. A newly frozen version of HABIT 1.1 replaced the one formerly available from ESTSC. Please browse the computer code abstracts available at RSICC's www site for more information on these packages.

CHANGES TO THE COMPUTER CODE COLLECTION

Three changes or additions were made to the computer code collection during the month. Three new code systems were packaged and added to the collection. One change resulted from a foreign contribution.

Pacific Northwest National Laboratory, Richland, Washington, contributed this code system for evaluation of control room habitability. HABIT 1.1 is a suite of computer codes designed for evaluating control room habitability in the event of an accidental release of toxic chemicals or radioactive materials. EXTRAN, CHEM, TACT5, FPFP_2, and CONHAB are included in the system. Given information about the design of a nuclear power plant, a scenario for the release of toxic chemicals or radionuclides, and information about the air flows and protection systems of the control room, HABIT can be used to estimate the chemical exposure or radiological dose to control room personnel. It runs on IBM-compatible PCs under DOS 5.0 or higher and can be run in a DOS window of Windows95. References: NUREG/CR-6210, PNNL-10496 (June 1996) and NUREG/CR-6210 Supplement 1 (September 1998). Fortran; IBM PC (C00665/IBMPC/00).

Oak Ridge National Laboratory, Oak Ridge, Tennessee, contributed this code system which processes DORT boundary-flux files to prepare input boundary sources for other DORT calculations. Note that DORT is not included in this package but is distributed within the CCC-650/DOORS code package. BSPRP2 handles both regular and variable-mesh geometries. Scale factors may be applied to normalize the source or to correct for streaming. [When correcting for streaming, the code assumes flat spatial distributions of the factors over two ranges and a cosine-power transition (varying by group) between the regions.] For the new DORT problem, the code will calculate a source for a different mesh and/or a different quadrature. Several options are available for converting the fluxes from one mesh/quadrature to another and for normalizing the output source to that for the portion of the input boundaries spanned by the output geometry. Direction-integrated group sources are printed after the mesh change and after the quadrature change if any. These should be the same values printed by DORT for a calculation using the new source.

The system runs on IBM RS/6000 under AIX 4.2 using the XLF Fortran 77 compiler. The package is transmitted on a CD-ROM which includes the BSPRP2 source files and test case input and output written as a compressed Unix tar file. Reference: ORNL Intra-Laboratory Correspondence (September 22, 1980). Fortran 77; IBM RS/6000 (P00372/IRISC/00).

Paul Scherrer Institut, Switzerland, through the Nuclear Energy Agency Data Bank, Issy-les-Moulineaux, France, contributed this code system to prepare broad-group neutron cross sections for use in diffusion and/or transport theory codes from an input library of fine group and pointwise cross sections. The code system, which is called MICROX-2, is an improved version of MICROX, developed at General Atomic. The MICROX-2 code can explicitly account for the overlap and interference effects between resonances in both the resonance and thermal neutron energy ranges and allows the simultaneous treatment of leakage and resonance self-shielding in doubly heterogeneous lattice cells. Using data from the pointwise and groupwise NJOY tapes, the included stand-alone MICROR reformatting program produces files containing basic nuclear data, FDTAPE, GAR and GGTAPE, to be used by two-region spectrum codes MICROX or MICROX-2 and by the two-region spectrum burn-up code MICROBURN. Note that NJOY is required to prepare input decks to the MICROR module and is not included in this package.

The neutron weighting spectrum is obtained by solving the B1 neutron balance equations at about 10000 energies in a one-dimensional (planar, spherical, or cylindrical), two-region unit cell. The regions are coupled by collision probabilities based upon spatially flat neutron emission. Energy dependent Dancoff factors and bucklings correct the one-dimensional cell calculations for multi-dimensional lattice effects. A critical buckling search option is also included. The inner region may include two different types of fuel particles (grains).

The PSI version of the MICROX-2 code operates on CRAY under Unicos 9 and DEC Alpha workstation running Unix 4.0C, as well as on an IBM PC. Installation requires a Lahey LF90 Fortran compiler for the IBM PC. Fortran 90 compilers are also required for installation on the CRAY J90, CRAY-Y/MP, or DEC computers. Included are the MICROX-2 and MICROR Fortran source codes, updates, makefiles, and selected ENDF/B data sets for test cases, sample problem input and output. The package is transmitted on CD-ROM in both Unix and DOS formats. References: PSI Bericht Nr. 97-11 (November, 1997), TM-41-97-17 (November, 1997), EIR-Beiricht Nr. 539 (December, 1984).

Errata

In the December 1996 Newsletter, the release of CCC-662/EASY4.1 was announced. The UKAEA, Fusion, Culham Science Centre, United Kingdom, developed and contributed this multipurpose activation and transmutation code system called European Activation System (EASY 4.1). In the announcement AEA Technology was erroneously credited for the contribution. We apologize for the mistake.

SCALE Criticality Safety Training Course--Europe

We have received several requests from SCALE users for organising the next SCALE training course in Europe. As you may know already, from 20-24 September 1999 the "International Conference on Nuclear Criticality Safety (ICNC'99)" will take place in Versailles, France; http://www.ipsn.fr/icnc99/. We have found it therefore convenient to organise this training course the week before that conference. This will facilitate both attendance in the criticality safety training course and be part of the last major event in criticality safety of this decade (sorry but I shall not use the term millennium).

We plan to hold this training course in the premises of the French National Institute for Nuclear Science and Techniques (INSTN) located about 6 miles from Versailles. The course will be given by the authors and code managers from the ORNL (http://www.cad.ornl.gov/scale).

The technical programme of the workshop has been designed by Steve Bowman, SCALE Project Leader, Computational Physics & Engineering Division, Oak Ridge National Laboratory (phone +1 423-574-5263, fax+1 423-576-3513, email st5@ornl.gov). An attendance certificate will be delivered at the end of the course. This course is organised in co-operation with the Radiation Safety Information Computational Center (RSICC). Should you be interested in participating, please return the form by 31 December 1998. More precise information, including the exact participation fee, location, transportation and accommodation possibilities will be provided later.
