This work highlights the many uses of these reactors, which have very different designs, use highly varied quantities of radioactive substances with varying levels of risk for safety and radiation protection, and which - in many cases because they are old or have been shut down - require appropriate measures to control the ageing or obsolescence of some of their equipment, as well as, on an organisational and human level, to ensure that they continue to be operated safely. For some research reactors, safety and radiation protection aspects must be considered, taking into account that two types of operators are present at the same time within these reactors: reactor operating personnel and operators in charge of experimental devices using neutrons from the reactor for fundamental or applied research purposes. There are two specific chapters on the safety standards established under the aegis of the IAEA for research reactors and on serious accidents, notably those involving criticality and reactivity, in research reactors. The second part of the work focuses on French research reactors, including the regulations and official documents applicable to these reactors, on lessons learned in France from significant events and accidents - as well as abroad, such as the Fukushima Daiichi nuclear power plant accident in 2011 - on the consideration of reactivity accidents in the design of French research reactors, and on the ten-yearly safety reviews carried out in France. 606 $aNuclear energy 615 0$aNuclear energy. 676 $a621.48 700 $aCouturier$b Jean$01054423 702 $aGrolleau$b Emmanuel 702 $aYe?hia$b Hassan Abou 801 0$bNjHacI 801 1$bNjHacl 906 $aBOOK 912 $a9910688578803321 996 $aElements of nuclear safety - Research reactors$93394353 997 $aUNINA LEADER 01907nam 2200373 450 001 9910136020703321 005 20231207090454.0 010 $a0-7381-9644-4 035 $a(CKB)3780000000090205 035 $a(NjHacI)993780000000090205 035 $a(EXLCZ)993780000000090205 100 $a20231207d2015 uy 0 101 0 $aeng 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 10$aIEEE Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers /$fIEEE 210 1$aNew York, N.Y. :$cIEEE,$d2015. 215 $a1 online resource (x, 66 pages) $cillustrations 225 1 $aIEEE Std ;$v1789-2015 320 $aIncludes bibliographical references. 330 $aThis document includes a definition of the concept of modulation frequencies for light-emitting diodes (LEDs), a discussion on their applications to LED lighting, a description of LED lighting applications in which modulation frequencies pose possible health risks to users, a discussion of the dimming of LEDs by modulating the frequency of driving currents-voltage, and recommendations for modulation frequencies (flicker) for LED lighting and dimming applications to help protect against known potential adverse health effects. 410 0$aIEEE Std ;$v1789-2015. 517 $aIEEE Std 1789-2015: IEEE Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers 606 $aModulation-doped field-effect transistors 615 0$aModulation-doped field-effect transistors. 676 $a621.3 801 0$bNjHacI 801 1$bNjHacl 906 $aDOCUMENT 912 $a9910136020703321 996 $aIEEE Recommended Practices for Modulating Current in High-Brightness LEDs for Mitigating Health Risks to Viewers$93646785 997 $aUNINA
