The Research Of The Safety Evaluation Methord And Its Application Of The Industry Safety System In The Nuclear Institute

The nuclear profession is the important part of the nationai economy. nuclearinstitute is the basic research unit of nuclear science technique. Its main businesscontents are the development and research of research items, it is the premise work ofthe other production units in nuclear fuel circulation chain. Its realm and businessscope are more widely, its safety involves two generous sides: nuclear and radiationsafety and industrial safety, from the variety trouble in nuclear institute recent years,the industrial production safety trouble is improtant, so it is urgent to insure industrialsafety in nuclear institute. Only carries on the valid safety evaluation for the industrysafety system in nuclear institute, basised on the analysis evaluation result, find outthe dangerous and weak links, and establish the valid of safety counterplan measuresaimed at it, then can makes the aim of “give priority to preventing”really, advance thesafety administment level of the industry safety system in nuclear institute. Therefore,The text processes the application study of the mode of the safety evaluation of theindustry safety system in nuclear institute has count for much of reality meaning.This text elaborates the creation, the development and the actuality, and there areless mode for the industry safety system in nuclear institute, launch to set up a set ofreasonable, viable safety evaluation mode methord for the industry safety system innuclear institute. Research the methord study basis of the safety evaluation within theindustry safety system in nuclear institute, analysis dangerous, harmful factors in theindustry safety system in nuclear institute, put forward the safety evaluation step, setup a set of science reasonable, maneuverable safety evaluation mode for it, and with one machine process place for the research object, carries on safety evaluationverification, certificates the rationality and possibilityof the safety evaluation mode.First, uses the " craft process－equipments－personnel" dangerous, harmfulfactor analysis method, analysis the dangerous, harmful factors and latent troublesand injury types existed in the system. The second, adopt in PHA to analysis thedangerous, harmful factors and latent trouble types on macro view, include analysisand research the trigger condition for the dangerous factors change to dangerous state,and the essential conditions for the dangerous state change to disasters, then confirmthe risk grade.The third, consider comprehensively and select the risks which havehigher risk grade, Be the top affairs, adopt in FTA method to analysis and evaluate thereasons for arousing the risk, list the all basic affairs cause arousing the top affairs,calculatiestructure importance of these basic affairs, and arrange them in row.thefourthly, establish the safety checklist for insuring the measure implemented validly.Finally, This text apply the safety evaluation mode which put forward, to themachine process workplace in CIAE, analysis the dangerous, harmful factor and thedangerous, existed in the system, adopt in PHA to analysis the dangerous, harmfulfactors and latent trouble types on macro view, include analysis and research thetrigger condition for the dangerous factors change to dangerous state, and the essentialconditions for the dangerous state change to disasters, then confirm the risk grade,consider comprehensively and select four kinds risks which have higher risk grade, Bethe top affairs, adopt in FTA method to analysis and evaluate the reasons for arousingthe risk, list the all basic affairs cause arousing the top affairs, calculatiestructureimportance of these basic affairs, and arrange them in row, establish the safetychecklist for insuring the measure implemented validly. This certificate the rationalityand possibility of safety evaluation mode machine buildded up for the machineprocess places. The safety evaluation mode, the safety counterplan measures and thesafety checklist, can advance to work betterly for organization and can be thereference for other organizations who to do safety work well.It is very necessary and important to carry on safety evaluation for the industrysafety system in nuclear institute. handles integratedly PHA and FTA, distinguish the dangerous, harmful factors and latent trouble types, assurance its risk grade, pass thevalid of analysis estimate, can to put forward counterplan measures, pass to imply thesafety technique measures and management measures, avoid or decrease the industryindustry safety troubles, improve the the industry safety system in nuclear institutesafety condition, guarantee body safety of the employee, and attain purpose of thesafety produce. The safety evaluation mode which puted forward can make theindustry safety field in nuclear institute safety evaluation of systematize,rationalization with scientific, it laies foundation and have important reality meaning,for carries on safety evaluation work for t the industry safety system in nuclearinstitute.
