ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The current RFX-mod machine control system relies upon proprietary products for control (PLCs) and supervision (SCADA). To improve the software versatility and to overcome increasing difficulties with legacy products, a major overhaul is being implemented. The new architecture retains the modularity of the current one, but Javais used to program most of the control tasks and the graphical user interfaces, moving the control functions to a new PC-based layer. The physical layer of the communication employs Industrial Ethernet technology for the local area network; data exchange is based on TCP/IP and OPC communication protocols, and on MDS plus technology. The master scheduler talks to non-PLC subsystems using TCP/IP and exchanges data with the tasks on the PLCs through the MDS plus transport layer and OPC. One Windows PC hosts the OPC and MDS plus servers; other PCs execute the control functions and provide the graphical user interface.This paper describes and analyses the current architecture of the RFX-mod machine control system and the renewed one, which is under development. The first encouraging tests, concerning mainly the communication performance, are reported.
