TheDepartment of Research Reactors and Tandem Accelerator is in charge of theoperation, utilization and technical development of JRR-3(Japan Research Reactor No.3),
JRR-4(Japan Research Reactor No.4), NSRR(Nuclear Safety Research Reactor) and Tandem
Accelerator.
This annual report describes a summary of activities of services and technicaldevelopments carried out in the period between April 1, 2010 and March 31, 2011. The
activities were categorized into five service/development fields:(1) Operation and maintenance of research reactors and tandem accelerator(2) Utilization of research reactors and tandem accelerator(3) Upgrading of utilization techniques of research reactors and tandem accelerator(4) Safety administration for research reactors and tandem accelerator(5) International cooperation.
Also contained are lists of publications, meetings, granted permissions on lows andregulations concerning atomic energy, commendation, outcomes in service and technicaldevelopments and so on.

水銀柱ミリメートル mmHg 1mmHg=133.322Pa(a)SI接頭語は固有の名称と記号を持つ組立単位と組み合わせても使用できる。しかし接頭語を付した単位はもはや
コヒーレントではない。
(b)ラジアンとステラジアンは数字の１に対する単位の特別な名称で、量についての情報をつたえるために使われる。
実際には、使用する時には記号rad及びsrが用いられるが、習慣として組立単位としての記号である数字の１は明示されない。
(c)測光学ではステラジアンという名称と記号srを単位の表し方の中に、そのまま維持している。
(d)ヘルツは周期現象についてのみ、ベクレルは放射性核種の統計的過程についてのみ使用される。
(e)セルシウス度はケルビンの特別な名称で、セルシウス温度を表すために使用される。セルシウス度とケルビンの単位の大きさは同一である。したがって、温度差や温度間隔を表す数値はどちらの単位で表しても同じである。
(f)放射性核種の放射能（activity referred to a radionuclide）は、しばしば誤った用語で”radioactivity”と記される。
(g)単位シーベルト（PV,2002,70,205）についてはCIPM勧告2（CI-2002）を参照。
