15、ndix A of ANSI0ANS-8.1-1998 R2007! reminds us that the few criticalityaccidents that occurred worldwide resulted from a failure to anticipate theunexpected in fissionable material handling and processing operations. To be acriticality safety engineer, one must not only be familiar with nuclear criti
16、calityand the factors that influence it but also recognize that criticality safety is onlymeaningful within the context of fissionable material operations. Minimizing therisk of a criticality accident to an acceptable level within the scope of operationsis the basic function of every person who work
17、s in the field of criticality safety.This requires personnel who are thoroughly familiar with fissionable materialprocesses and who work in close cooperation with operations personnel andmanagement. The goal of the criticality safety engineer is to assist operatingpersonnel in the conduct of safe an
18、d efficient operations while maintaining anacceptably low risk of a criticality accident.The art and science of nuclear criticality safety are complex. In addition tonuclear physics, an effective criticality safety engineer develops a multidisciplin-ary understanding of electricalsoftware, hardware!
19、, chemical, mechanicalstruc-tural, heat transfer!, material, industrial procedural, ergonomic!, humanperformance behavioral!, and economic issues related to fissionable materialprocess control.Key elements of an effective training program include an understanding of theimpact of controlled parameter
20、s on the reactivity of a defined system and anability to effectively predict the reactivity of a system or process. A careful reviewof lessons learned from previous criticality accidents and other site-specificnonconformances can also be considered.Training to the program content elements in this st
21、andard can enable criticalitysafety engineers to become effective advocates to foster a nuclear safetyconscious workforce and sound nuclear safety practices in support of facilityoperations personnel. One key element of the training program is practicalexperience with the parameters that affect the
22、neutron multiplication of fission-able material systems. This experience can be achieved through hands-on criti-cality safety courses, conduct of experiments in a research reactor environment,or participation in critical experiments.This standard provides guidance for the content of training program
23、s for nuclearcriticality safety specialists who are responsible for developing the analyses,controls, and safety documentation required for the safe handling of fissionablematerials. This standard presents a matrix of training and qualification criteriabased on education and experience combined with
24、 individual job functions andprovides for qualification of experienced staff by documentation. This standardstresses the necessity to integrate standard training subjects with operationalexperience in order to qualify as a criticality safety engineer.This standard does not specify how to develop or
25、execute these training andqualification programs; it provides only the elements that should be included inthe programs. It is not intended that these programs lead to any professionalengineer certification, only that they create a common basis for criticality safetyengineer qualification across the
26、diverse organizations that rely on these spe-cialists. Standard criteria for establishing scopes, functions, and levels of com-petence for safety professionals are available in ASSE0ANSI Z590.2-2003 andASSE0ANSI Z590.1-200X, published or in draft form by the American Society ofSafety Engineers.iThis
