If there is righteousness in the heart there will be beauty in the character. If there be beauty in the character, there will be harmony in the home. If there is harmony in the home, there will be order in the nation. When there is order in the nation, there will be peace in the world.---Chinese Proverb

It is a sincere pleasure to serve you.
We value your friendship, confidence and
loyalty and can think of no more appropriate
time than now to tell you so.

May the coming year be a most Happy and Healthful
one for you and your family.

CHANGES TO THE COMPUTER CODE COLLECTION

Three changes were made to the computer code collection during the month. Two existing code packages were replaced with newly frozen versions and an existing code package was corrected.

CCC-641/NESTLE 5.02

OP SYS: UNIX, ULTRIX
Language: Fortran 77
Computers: workstation
Format: tar

North Carolina State University, Raleigh, North Carolina, contributed a newly frozen version of this code system which solves the few-group neutron diffusion equation utilizing the nodal expansion method (NEM). NESTLE can solve eigenvalue (criticality), eigenvalue adjoint, external fixed-source steady-state, and external fixed-source or eigenvalue initiated transient problems. The eigenvalue problem allows criticality searches to be completed, and the external fixed-source steady-state problem can search to achieve a specified power level. Three-, two-, and one-dimensional models can be utilized with various symmetries.
The new version of NESTLE 5.02 includes the option to utilize a Weilandt Eigenvalue Shift method in place of the Semi-Implicit Chebyshev Polynomial method to accelerate the outer iterations. In addition, flux, fission source and power density are now exponentially extrapolated to the new time-step time value to improve convergence. Other features added include the following: implicit or explicit transient T-H feedback option, specification of whether convergence after a NEM/T-H update is demanded, frequency of NEM coupling coefficients update based upon L2 fission source relative error reduction, execution time specification of control file name, input echo execution option, and improved run-time statistics. In addition, various minor bugs were fixed, and code restructuring was implemented to increase computational performance and coding clarity. Details of all code changes can be found within file main.f.
NESTLE is written in Fortran 77 and runs on Unix workstations with at least 16 megabytes of memory. It has been tested on IBM RS/6000 running AIX, HP9000/700 running HPUX, DEC5000 running Ultrix, and SUN OS platforms. Three DS/HD 3.5-in. (1.44 MB) DOS diskettes are used to transmit Unix compressed tar files which contain the source code, makefiles, test problem input/output, electronic dictionary and database. Reference: EGG-NRE-11406 (June 1994). Unix Workstations; Fortran 77 (C00641/MNYWS/01).
PSR-158/SAMMY-K1

OP SYS: UNIX, VMS
Language: Fortran 77
Computers: RS/6000, DEC ALPHA
Format: tar

Oak Ridge National Laboratory contributed updates to the SAMMY-K1 code system for calculating multilevel R-matrix fits to neutron data using Bayes' equations. These updates are primarily related to portability on VMS with minor modifications to 2 Unix scripts. Users who have SAMMY-K1 and want the updates only may request that they be sent on a 1.44 DS/HD 3.5-in. diskette in DOS format. The documentation was updated with the publication of ORNL/TM-9179 Rev. 3, which was previously issued in draft form.
The system runs on the IBM RS/6000 and has been ported to DEC Alpha computers under both Open/VMS and OSF1 operating systems. SAMMY-K1 is transmitted in tar format on either a CD-ROM or cartridge tape. References: ORNL/TM-9179 (Aug. 1984), /R1 (July 1985), /R2 (June 1989), and Rev. 3 (Sept. 1996). Fortran 77; IBM RS/6000 and DEC (P00158/IRISC/03).
PSR-355/NJOY 94.61

OP SYS: CTSS, UNICOS, UNIX
Language: Fortran 77
Computers: many
Format: tar

Los Alamos National Laboratory, Los Alamos, New Mexico, contributed a newly frozen version of this code system for producing pointwise and multigroup cross sections from ENDF/B evaluated nuclear data, including ENDF/B-VI. The new version designated NJOY94.61 fixes problems which were found and corrected by updates 36-61, which involve changes to the acer, ccccr, errorr, groupr, matxsr, dtfr, heatr, gaspr, leapr, moder, njoy, reconr, and thermr modules.
The NJOY94.61 release is configured for UNIX. The test problem input files are UNIX shell scripts, and the test problem results are from runs on a Cray Y-MP8/4-64 running UNICOS. The code runs on Cray/UNICOS, Cray/CTSS, IBM, VAX/VMS, and Sun workstations and is transmitted on either 1 CD-ROM, DC 6150 (150 MB) cartridge, 4-mm, or 8-mm tape in tar format. The updates are available on one 1.44 DS/HD 3.5-in. diskette written in DOS format. Users who already have NJOY94 may request that the updates be sent on diskette. References: LA-12740-M (Oct. 1994).

CONFERENCES, COURSES, SYMPOSIA

NOVEMBER ACCESSION OF LITERATURE

The following literature cited has been ordered for review, and that selected as suitable will be placed in the RSICC Information Storage and Retrieval Information System (SARIS). This early announcement is made as a service to the shielding community. Copies of the literature are not distributed by RSICC. They may generally be obtained from the author or from a documentation center such as the National Technical Information Service (NTIS), Department of Commerce, Springfield, Virginia 22161. For literature listed as available from INIS contact INIS Clearinghouse, International Atomic Energy Agency, P.O. Box 100, A-1400 Vienna.

RSICC maintains a microfiche file of the literature entered into SARIS, and duplicate copies of out-of-print reports may be available on request. Naturally, we cannot fill requests for literature which is copyrighted (such as books or journal articles) or whose distribution is restricted.

This literature is on order. It is not in our system. Please order from NTIS or other available source as indicated.
