2、n. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 Intent:1.1.1 The intent of this guide is to provide general design and operating considerations for the safe and dependable operat

3、ionof remotely operated hot cell equipment. Hot cell equipment is hardware used to handle, process, or analyze nuclear or radioactivematerial in a shielded room. The equipment is placed behind radiation shield walls and cannot be directly accessed by the operatorsor by maintenance personnel because

4、of the radiation exposure hazards. Therefore, the equipment is operated remotely, either withor without the aid of viewing.1.1.2 This guide may apply to equipment in other radioactive remotely operated facilities such as suited entry repair areas,canyons or caves, but does not apply to equipment use

5、d in commercial power reactors.1.1.3 This guide does not apply to equipment used in gloveboxes.1.2 Applicability:1.2.1 This guide is intended for persons who are tasked with the planning, design, procurement, fabrication, installation, ortesting of equipment used in remote hot cell environments.1.2.

6、2 The equipment will generally be used over a long-term life cycle (for example, in excess of two years), but equipmentintended for use over a shorter life cycle is not excluded.1.2.3 The system of units employed in this standard is the metric unit, also known as SI Units, which are commonly used fo

7、rInternational Systems, and defined by IEEE/ASTM SI 10:American National Standard for Use of the International System of Units(SI): The Modern Metric System.1.3 Caveats:1.3.1 This guide does not address considerations relating to the design, construction, operation, or safety of hot cells, caves,can

8、yons, or other similar remote facilities. This guide deals only with equipment intended for use in hot cells.1.3.2 Specific design and operating considerations are found in other ASTM documents.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

34、al guidelines for the design and operation of hot cell equipment to ensurelongevity and reliability throughout the period of service.4.2 It is intended that this guide record the general conditions and practices that experience has shown is necessary to minimizeequipment failures and maximize the ef

35、fectiveness and utility of hot cell equipment. It is also intended to alert designers to thosefeatures that are highly desirable for the selection of equipment that has proven reliable in high radiation environments.4.3 This guide is intended as a supplement to other standards, and to federal and st

36、ate regulations, codes, and criteria applicableto the design of equipment intended for hot cell use.4.4 This guide is intended to be generic and to apply to a wide range of types and configurations of hot cell equipment.5. Quality Assurance Requirements5.1 The manufacturer and Owner-Operator of hot

37、cell equipment should have a quality assurance program. QA programs maybe required to comply with 10CFR830.120, ANSI/ASME NQA-1, or ANSI/ISO/ASQ 9001.5.2 The Owner-Operator should require appropriate quality assurance of purchased hot cell equipment to assure proper remoteinstallation, operation and

38、 reliability of the components when they are installed in the hot cell.5.3 Hot cell equipment should be designed according to quality assurance requirements and undergo quality control inspectionsas outlined by the authority having jurisdiction.6. Nuclear Safety6.1 The handling and processing of spe

39、cial nuclear materials requires the avoidance of criticality incidents. Equipment intendedfor use in handling materials having a special nuclear material content should undergo a criticality assessment analysis inaccordance with the requirements of ANSI/ANS-8.1 and other such standards and regulatio

40、ns as may be applicable.7. Design Considerations7.1 Hot cell equipment should be designed and fabricated to remain dimensionally stable throughout its life cycle.7.2 Fabrication materials should be resistant to radiation damage, or materials subject to such damage should be shielded orplaced and att

41、ached so as to be readily replaceable.7.3 Special consideration should be given to designing hot cell equipment that may be exposed to or may create hightemperatures, high rate of temperature changes, caustic conditions, or pressure changes.Abrupt changes in the hot cell temperatureor pressure may c

42、ause the hot cell windows to crack, lose clarity, and potentially lose containment and cause liquid spillage. Referto Guide C1572 for information regarding hot cell windows. The effect of handling and operating high temperature hot cellequipment utilizing master-slave manipulators or other in-cell h

43、andling equipment should be considered to preclude damage tothose items.7.4 Preventive maintenance based on previous experience in similar environments and similar duty should be performed asrequired to prevent unscheduled repair of failed components.7.5 Hot cell equipment may be required to be leak

44、-tight when handling liquids. Leak tightness prevents radioactive liquid fromentering the interior of hot cell equipment where it can cause corrosion, shorting of electrical components, higher chronic radiationto components and it complicates decontamination.7.6 Hot cell equipment should generally b

45、e designed to function indefinitely, or within a pre-planned specified life cycle withinthe highly radioactive environment. However, in many cases this may not be possible since radiation degrades some materials overtime. Alpha, beta, gamma, and neutron radiation can severely damage most organic mat

46、erials, for example, oils, plastics, andelastomers. Materials that come into direct contact with alpha- and beta-emitting materials can experience severe radiation damagedue to the large amount of energy transferred when stopping the alpha and beta particles. Commercially available equipmentcontaini

47、ng organic materials may require disassembly and the internal components replaced with more radiation resistant materials.If suitable alternate materials cannot be used, special shielding may have to be integrated into the design to protect the degradableC1533 153components. In the case of some elec

48、tronic equipment, it may be possible to separate and move the more radiation sensitivecomponents outside of the hot cell and operate the equipment in the hot cell remotely. Where possible and appropriate, equipmentshould be designed to withstand an accumulative radiation dose of approximately 1 108

49、rads (H2O)60Co.7.7 Since hot cells have a limited amount of space, the equipment designs should be standardized where possible to reduce thenumber of one-of-a-kind parts. Standardization of hot cell equipment will reduce design time, fabrication costs, operator trainingtime, maintenance costs, and the number of special tools required to perform a certain operation. Standardization in design,drawing control and excellent quality control assure that components are interchangeable. Specially designed equipment shouldbe standardized for use with equipm
