ADVANTAG 3.0.1 Users
The ADVANTG 3.0.1 developers have notified us that the ADVANTG-3.0.1 (C831MNYCP00) software contains an error that affects the application of ADVANTG to MCNP models that contain specularly reflective (symmetry) boundary conditions. Specifically, the bug prevents the operation of the geometry unfolding capability, which is activated using the `mcnp_unfolding_origin` input keyword. This bug has been corrected in ADVANTG-3.0.3. In addition, the robustness and performance of the unfolding code have been significantly improved.

If you require this corrected functionality, you may do ONE of the following:

1) Request the ADVANTG 3.0.1 patch by sending an email to to request ADVANTG 3.0.1 Addendum, package ID C831MNYCP01. Please note, if you request the patch, the included files will apply code changes to the ADVANTG source. You will need to re-compile the source code, no new executables are provided in the patch itself.


2) If you do not wish to recompile the code, please submit a new request for ADVANTG 3.0.3, package ID C831MNYCP03 from the Customer Service page,

RSICC Deploys Secure Cloud Server

RSICC would like to inform our customers that we are deploying a secure cloud computing system that will be made available to our customers that meet following criteria:

1. The individual is from a country for which a specific export authorization would be required;
2. The individual would likely be denied or have restricted access to software; and
3. It is in the interest of the U.S. government to provide access to the software.

Individuals that meet the criteria listed above and are in one of the following categories will automatically be considered for access:

1. Individuals that indicate that they are collaborating with US organizations such as US national laboratories or US universities;
2. Individuals that indicate that they are teaching or conducting research at US universities; and
3. Students at US universities.

Other individuals may be granted access to the secure cloud as requested by RSICC’s sponsors and approved by RSICC’s regulators.

RSICC will screen all requests for MCNP6.1, SCALE6.1 and RELAP5/MOD3.3 to determine if an individual qualifies for access to RSICC’s secure cloud computing system. The request will be submitted to our regulators. If approved, the customer will be required to provide specific information to RSICC and agree to certain terms and conditions before being granted access to the system. Individuals that are approved will not be permitted to utilize these codes except on RSICC's secure cloud computing system. If an individual is approved for access to RSICC's secure cloud computing system and does not consent to the terms and conditions, the individual's request will be mark as denied.

The deployment of this system will allow RSICC to grant use of certain codes to some of our customers who otherwise would not be authorized. RSICC would like to thank its sponsors, the Department of Energy's Office of Nuclear Energy and the National Nuclear Security Administration's Office of Nonproliferation and Arms Control, for supporting the development and deployment of this system.

Safety Analysis Report for Packaging (SARP)
Shielding/Criticality Safety Generalist and Analyst Courses
Developed and Conducted by Oak Ridge National Laboratory

Radioactive Material Package Shielding Evaluation and Nuclear Criticality Safety Evaluation Training:

The U.S. Department of Energy (DOE) Packaging Certification Program (PCP), Office of Packaging and Transportation, is offering Safety Analysis Report for Packaging (SARP) shielding and nuclear criticality safety (NCS) courses for SARP generalists and analysts.

June 6-10, 2016
The SARP Generalist Course is designed for project managers, supervisors, NCS/shielding subject matter experts (SME), or SMEs in non-NCS/shielding technical areas (e.g., structural, thermal, package design, etc.) who need to better understand how the NCS/shielding analyses fit in the broader SARP documentation. Specifically, the Generalist Course provides an overview of the regulations and guidelines for the criticality and shielding analysis for a SARP, and the course shows how the NCS/shielding chapters integrate with the other parts of the SARP. Students in the Generalist Course will review an actual SARP document after the course material is presented to emphasize the key elements of the shielding and criticality analyses.

Sept. 12-16, 2016
The Analysts Course will provide detailed training on the radioactive material package shielding analyses and NCS evaluation fundamentals needed by analysts/practitioners (i.e., safety analysts and/or technical reviewers) to prepare and/or review technical analyses for the SARP documentation. The Analyst Course also provides an overview of regulations and guidelines in addition to detailed in-class exercises associated with the package shielding and NCS analyses. With regard to the in-class exercises, analysis teams will be faced with “staged” SARP examples in which a number of important decision processes in the generation of a SARP will be demonstrated and discussed.

Both the SARP Generalist and SARP Analyst Courses will be offered in Fiscal Year 2016.

The SARP Generalist Course will be held at Oak Ridge National Laboratory in Oak Ridge, TN. The SARP Generalist Course is scheduled for June 6-10, 2016.

The SARP Analyst Course is scheduled for Sept. 12-16, 2016 also at Oak Ridge National Laboratory in Oak Ridge, TN.

Further information will be posted as soon as it is available.
