14、rvedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which

15、 a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all mat

16、ters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circu

17、lated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsi

18、ble for identifying any or all such patent rights. ISO 17874-1 was prepared by Technical Committee ISO/TC 85, Nuclear energy, Subcommittee SC 2, Radiation protection. This second edition cancels and replaces the first edition (ISO 17874-1:2004), which has been technically revised. ISO 17874 consists

19、 of the following parts, under the general title Remote handling devices for radioactive materials: Part 1: General requirements Part 2: Mechanical master-slave manipulators Part 3: Electrical master-slave manipulators Part 4: Power manipulators Part 5: Remote handling tongs BS ISO 17874-1:2010ISO 1

20、7874-1:2010(E) ISO 2010 All rights reserved vIntroduction This part of ISO 17874 deals mainly with multipurpose remote handling devices for nuclear applications. These devices replace hands and arms in areas inaccessible to personnel (mostly behind shielding walls). There are special remote handling

21、 devices designed for narrow fields of application or for special purposes only, but these are beyond the scope of this part of ISO 17874. Multipurpose remote handling devices have five to ten, or even more, possibilities of movement in order to cope with the planned range of tasks. Four categories

22、of such remote handling devices are used worldwide for the handling of radioactive materials. These categories are the following: mechanical master-slave manipulators; electrical master-slave manipulators; power manipulators; remote handling tongs. Various special designs, hydraulic or pneumatic mac

23、hines, prototypes, experimental devices and obsolete types cannot be assigned to any category or do not correspond to all requirements of this part of ISO 17874. These devices are not covered by this part of ISO 17874. The main applications of the different categories are explained in Clause 4. Remo

24、te handling devices were originally developed for hot cells designed for research and development in nuclear power reactor fuel elements. They are now also in widespread use in other nuclear installations, such as plants for fabrication or reprocessing of fuel elements, waste treatment stations and

25、decommissioning of nuclear facilities. Remote handling devices are sometimes used for non-nuclear applications. This part of ISO 17874 does not address the special requirements of any of these fields, although designers can take advantage of standardized components from the nuclear sector to achieve

26、 cost-effective designs for other purposes, where appropriate.

27、ements concerning devices for remote handling of radioactive materials. The classification of these devices (categories and different designs within a category) and the distribution in the different parts are shown in Figure 1. Figure 1 Categories of remote handling devices and location in all parts

28、 of ISO 17874 Concerning the working volume, two principal designs are to be considered. a) Fixed remote handling devices: these devices are fitted in the shielding wall or sometimes in the ceiling of hot cells and accordingly can function only in a rather limited volume. Such devices are mechanical

29、 master-slave manipulators and remote handling tongs. BS ISO 17874-1:2010ISO 17874-1:2010(E) 2 ISO 2010 All rights reservedb) Mobile remote handling devices: these devices are fitted on a transporter (e.g. a moveable bridge or a vehicle on the ground). The working volume depends mainly on the possib

30、le motion of the transporter. Such devices are electrical master-slave manipulators and power manipulators. NOTE This part of ISO 17874 is intended to provide assistance to designers of nuclear process plants, as well as manufacturers, users and licensing authorities. 2 Normative references The foll

36、e mechanical transmissions NOTE The manipulator is generally mounted on a shielding wall. 3.2 electrical master-slave manipulator manipulator reproducing the movements of the hand and arm of the operator by means of isokinematic master and slave arms with bilateral electrical position control (force

37、 reflection) NOTE 1 The word “bilateral” refers to the property of the system to be indifferently moved by acting on the master arm or on the slave arm. NOTE 2 The slave arm is generally mounted on a transporter (mobile). BS ISO 17874-1:2010ISO 17874-1:2010(E) ISO 2010 All rights reserved 33.3 power

38、 manipulator manipulator driven by switch-operated motors 3.4 remote handling tongs mechanical device consisting of a gripper, a handle and a rod between them NOTE Remote handling tongs are either installed in a shielding wall by using a mounting device or hung on a carrying system for use in a wate

39、r pool or carried by an operator. 3.5 isokinematic property of a manipulator, where from base to free end, master arm and slave arm, presents the same type of motion (rotation or translation) in the same order and with the same relative orientations 4 Application of multipurpose remote handling devi

40、ces 4.1 General The different categories of remote handling devices are used for various applications, as described in this clause. 4.2 Mechanical master-slave manipulators 4.2.1 Mechanical master-slave manipulators with telescopic arms These manipulators allow the transmission of forces up to the m

41、aximum magnitude required for the tasks to be achieved manually by an unaided operator. Depending on the type of manipulator, maximum load capacities up to 45 kg can be reached (see 7.2). They are suitable for complicated tasks and are usually installed in pairs on a working station. They are design

42、ed for hot cells of all sizes with shielding walls of concrete or also of lead in some cases. They constitute the main working devices in such kinds of cells. Different lengths of arms are available according to the size of the hot cell to be equipped. However, versions with short arms provide highe

43、r forces and, reversely, versions with long arms reduce the forces to be applied. There also exist compact manipulators with a double telescope in the slave arm, available for hot cells with restricted height. 4.2.2 Mechanical master-slave manipulators with articulated arms These manipulators allow

44、not only the execution of forces equivalent to those an unaided operator can achieve, but also forces up to a much higher level. Depending on the type of manipulator, maximum load capacities up to 100 kg can be reached (see 7.2). They are suitable for complicated tasks, and are usually installed in

45、pairs on a working station. They are designed for hot cells of all sizes with shielding walls typically of lead or also of cast iron in some cases. They are also used in containment enclosures. They have small dimensions and therefore provide a relatively small working volume. They are used instead

46、of remote handling tongs as described in 4.5, if a larger working volume and/or more dexterity are needed. 4.3 Electrical master-slave manipulators These manipulators allow not only the execution of forces equivalent to those an unaided operator can achieve, but also (depending on the type) forces u

47、p to a much higher level. They are suitable for complicated tasks, and often they are installed in pairs. They allow the performance of complicated work throughout the whole volume of large hot cells and not only near the operation walls, by means of the mobility of the slave arm. As a result of the

48、ir load capacities they can be used also in place of light and medium load capacity power manipulators. They can be used, not only inside facilities, but also on vehicles (also in the open air). BS ISO 17874-1:2010ISO 17874-1:2010(E) 4 ISO 2010 All rights reserved4.4 Power manipulators These manipul

49、ators allow the execution of high forces and therefore the handling of heavy objects, typifying their application. According to the load capacity of their hoist, they can also be used like a crane of light load capacity. They are not suitable for complicated tasks. They are used in medium-sized or large hot cells. Normally, they have large dimensions and are used to assist mechanical master-slave manipulators. They are used for tasks to be performed in areas that cannot be reached by mechanical master-sl
