    1. What is GALE and what is it used for?
    GALE is the acronym for the Gaseous And Liquid Effluent code, which is a computerized mathematical model for estimating the releases of radioactive material in gaseous and liquid effluents (i.e., the gaseous and liquid source terms) from boiling-water (BWRs) and pressurized-water reactors (PWRs). The U.S. Nuclear Regulatory Commission uses the GALE code to determine conformance with the requirements of Appendix I to 10 Code of Federal Regulations (CFR) Part 50.


    2. Who typically uses the GALE code?
    The GALE code is one of the tools used by the NRC Offices of Nuclear Reactor Regulation (NRR) and New Reactors (NRO) to perform independent assessments of licensee applications and license amendments for existing plants (modifications to plant design or technical specification) pertaining to determine conformance with the requirements of Appendix I to 10 Code of Federal Regulations (CFR) Part 50.


    3. Is GALE only used domestically in the US?
    No, GALE is used by many international government agencies and is an important computer code in the US NRC’s Radiation Protection Computer Code Analysis and Maintenance Program (RAMP).


    4. Is there a forum that users can go to discuss questions related to the models used in the GALE coe?
    Yes, the GALE Forum is available to all visitors of the RAMP website (via “read-only” access). However, only RAMP members can post to the forum.

    RAMP members have several tools available to help them trouble shoot and resolve GALE error messages and code crashes. Users experiencing error messages or code crashes should log into the U.S NRC RAMP website and select the “GALE Support" navigation link. This link will triage them through the following trouble shooting steps:

    • Select the “Frequently Asked Questions (FAQs)” link to review the FAQs for the error message and if not listed then,
    • Select the “GALE Forum” link to review the “Error (Bug) Reports” forum board for the error message. If it is not listed the user can add this topic by, selecting the “ Add new forum topic” link on the “Error (Bug) Reports” forum board.

    2. Is there a “Help” tool associated with the GALE code?

    No, the GALE code does not contains a Help file; however, the technical information regarding the models and methods used by the GALE code to perform calculations can be found in the GALE User Guides and at the “GALE User’s Guide” web page on the U.S NRC RAMP website.

    3. Is there a contact phone number to receive help with the GALE software?
    No, there is no single contact phone number for the GALE software. Since GALE development and distribution is a collaborative effort between the US NRC RAMP and GALE Development Teams, users receive efficient and timely customer support by using the GALE Support navigation link on the U.S NRC RAMP website.
