    4th Quarter 2013

    Fourth RELAP5-3D Quarterly Newsletter of 2013
    October – December

    Editor: Dr. George Mesina

    Article Titles

    Article Summaries

    This quarter's lead article features information about an automated kinetics time step independent of the thermal hydraulics time step has been implemented to allow improved performance.

    The second article presents RELAP5-3D issues involving a requirement for left-to-right evaluation of Fortran if-clauses. This causes RELAP5-3D runtime errors on platforms that do not force this order. The issue has been resolved.

    Quarterly News and Information

    • The RELAP5-3D Version 4.1.3 has been released.
      • The IRUG Source code product includes the PVM Executive

    3rd Quarter 2013

    Third RELAP5-3D Quarterly Newsletter of 2013
    July – September

    Editor: Dr. George Mesina

    Article Titles

    Article Summaries

    This quarter's lead article features information about Out International RELAP5 User Group including membership growth and a breakdown of the categories of membership.
    The second article discusses performing deletion calculations with RELAP5-3D coupled with PHISICS. Results of a sample calculation are presented.
    The third article presents a brand new capability available in version 4.1.3 that allows a developer to apply sequential verification of the code through a highly accurate comparison capability.

    Quarterly News and Information

    2nd Quarter 2013

    The Second RELAP5-3D Quarterly Newsletter of 2013 covers some developments and news from April - June. The Quarter's lead article features information about Small Modular Reactors and how RELAP5-3D is being used to model and prepare them. The Consortium for Advanced Simulation of Light Water Reactors has integrated RELAP5-3D into VERA, the Virtual Environment for Reactor Applications. Developer Guidelines for programming RELAP5-3D have been released outside the INL for the first time at the request of clients who are modifying the code. And some of the upgrades to the code in this quarter are laid out in the final article.

    1st Quarter 2013

    This is the RELAP5-3D Quarterly Newsletter for the months of January - March, 2013. Discuss the challenge the differnt time scales involved in coupling depletion thermo hydraulic simulation. Learn more about the RELAP-3D station and the plant model. What do you need to know about the order of evaluations for RELAP-3D? Find out about the capabilities of modeling in moving environments. Discover the limiting areas in your model so you can optimize for execution results.



    Archives

    4th Quarter 2012

    This is the RELAP5-3D Quarterly Newsletter for the months of October - December, 2012. Discover information on the success of the transient analysis coupling of PHISICS within RELAP5-3D. Uncover resolutions to reported user problems. Want to create a new input file with updated initial conditions in RELAP5-3D? There's a newly updated Pygi to support that. Kinetics received a new redesign. The new memory structure now relies on allocatedable arrays and pointers.

    3rd Quarter 2012

    This is the RELAP5-3D Quarterly Newsletter for the months of July - December, 2012. This newsletter informs readers about recent activities, new developments, and upcoming events regarding the RELAP5-3D code, team, and International RELAP5 Users Group (IRUG).

    2nd Quarter 2012

    1st Quarter 2012

    The first issue, for January – March 2012, presents a baseline for the team and code. The team members and their roles are presented in the first article. Since justification of the switch from version 2.4 to Beta version 3.0 is necessary for many code users, the second article presents the recent Developmental Assessment (DA) of version 2.4; the DA of version 3.0 Beta will be presented in an article after the code release. Also listed are recent code developments and other information about the code, the team, and IRUG.

    Subsequent issues will contain more information than this inaugural issue. However, it is hoped that this initial information will be useful to the reader.
