1 Integrated radiation monitoring and interlock system for the LHD deuterium experiments Nakanishi H. with Safety & Env. Monitoring Team and LHD Information Systems Group National Institute for Fusion Science, NINS, Japan SOKENDAI, Japan
2 Objectives of LHD deuterium experiment 1. High-performance plasmas through confinement improvement Scientific research in more reactor-relevant conditions Full of research opportunities 2. Clarification of the isotope effect on confinement Long-standing mystery in world fusion research Needs to be understood towards burning plasma 3. Demonstration of the confinement capability of energetic ions in helical systems Perspectives towards helical reactor 4. Isotope effect on PWI Global particle balance for hydrogen isotopes
3 Schedule for LHD deuterium experiment - Concluded the agreements for LHD deuterium experiment with local governments in Deuterium experiment has started since March 2017 and will last 9 years 2013 Preparation for D-experiment Hydrogen Experiments Agreements for D-exp.

8 X(γ)-ray doses are monitored at 9 points on the site border ( ) and 5 points near the LHD building ( ). Neutron rem counters ( ) have been added for the deuterium experiment. X(γ) and neutron doses are always published on the Web. Environmental Radiation Monitoring RMSAFE ac.jp/map.php
9 Exhaust Gas Flow Monitor Air Flows must be monitored with the tritium densities and also the collection system. GUI is based on XAML & WPF/.NET framework. Exhaust Gas Flow Monitor Flowmeter

11 New Radiation Monitors Neutron yield (weekly / annually) Plasma derived cumulative dose (/Sv) (annually / 3 month) Gas radioactivity concentration (Bq/cm 3 ) (exhaust tower / torus hall) Radiation safety interlock signals
12 Alert Expressions Just for System Demo! Background color turns yellow if over 60% of controlled value. The letters turns red if over 80% of controlled value.
13 Summary LHD has successfully started the deuterium experiment since March The integrated radiation monitoring system has been newly implemented with the extension of the safety interlock functionalities. As for the related data acquisitions, both of 24 hour continuous and on-sequence operations have been realized with the virtual DAQ to distinguish the plasma derived dose. Not only sensors but also data acquisition nodes have been carefully designed to have enough redundancy for some radiation measurements.
