The Knolls Atomic Power Laboratory (KAPL), Bettis Atomic Power Laboratory and Rensselaer Polytechnic Institute (RPI) are holding a symposium on April 29 and 30, 2009 to share and discuss the state of development and testing for supercritical carbon dioxide (S-CO2) Brayton systems. The overall goal of the symposium is to review recent progress in the field and discuss future needs and priorities among the various attending organizations. This symposium follows a similar meeting held at the Massachusetts Institute of Technology in 2007.

Symposium Overview

The S-CO2 Brayton system may provide competitive efficiencies with substantially smaller and less complex equipment than conventional plants. S-CO2 Brayton systems offer performance and cost advantages in conventional power production and advanced nuclear reactor systems.

The symposium will review the status of overall development, including:

System Concepts (both conventional and nuclear)
System Modeling and Control
Fundamentals of S-CO2 Fluid Mechanics & Heat Transfer
Materials Issues for S-CO2 Systems
Heat Exchanger Design
Turbomachinery Design
Electrical Generator Design
Small Scale System Testing
Large Scale Test Plans
Integrated View of Development Priorities

The objectives of the meeting are to share the status of world developments, discuss feedback on development status and direction from participants, and obtain an integrated view of development priorities. The perspective gained will allow researchers to better coordinate work and allow the participants greater insight into overall direction of this technology.

Format of Symposium

The symposium will be arranged based on topical areas with presentations held over the course of two days. The length of the presentations will be 20-30 minutes. On both days, a poster session area will be provided for display and review by participants during breaks from the formal sessions.

General Guidelines


The contents of the abstract must include the objectives of the study/investigation and the methodology used. It should also briefly describe the main findings and their potential applications. Sufficient information should be included for an independent reviewer to determine its suitability for the symposium. Authors are encouraged to submit full-length papers along with their presentations to provide full documentation of their work. However, presentations will be accepted without papers as long as they provide sufficient technical details of the work. Selected papers from the symposium will be recommended for publication in a special topical issue of an archival journal.

Acceptance Criteria:

Abstracts, papers and presentations are expected to contain descriptions of work that is significant and relevant to the symposium purposes. Documentation will be reviewed prior to acceptance by the scientific committee. Submissions should contain data and investigations that are of general interest, address problems of interdisciplinary significance or include in-depth discussions of scientific and technical issues. Documentation must be submitted electronically to both Ryan McNab at mcnabrj@kapl.gov and Tara Gallaway at gallat2@rpi.edu. All papers must be in English and no longer than 10 pages.


The final presentations and papers (if applicable) must be submitted electronically no later than March 31, 2009.

Author's Organizational and Personal Approval:

All internal reviews and organizational approvals must be completed prior to submittal. It is the responsibility of the author to protect proprietary information.

Additional Guidance:

The template for abstracts can be downloaded here. The template for all submitted papers can be downloaded here. Symposium proceedings, including all conference presentations and accompanying papers where available, will be provided to attendees. Symposium brochure
