Standard Guide for Viewing Systems for Remotely Operated Facilities
SIGNIFICANCE AND USE
4.1 Remote Viewing Components:
4.2 The long-term applicability of a remotely operated radiological facility will be greatly affected by the provisions for remote viewing of normal and off-normal operations within the facility. The deployment of remote viewing systems can most efficiently be addressed during the design and construction phases.
4.2.1 The purpose of this guide is to provide general guidelines for the design and operation of remote viewing equipment to ensure longevity and reliability throughout the period of service.
4.2.2 It is intended that this guide record the general conditions and practices that experience has shown are necessary to minimize equipment failures and maximize the effectiveness and utility of remote viewing equipment. It is also intended to inform designers and engineers of those features that are highly desirable for the selection of equipment that has proven reliable in high radiation environments.
4.2.3 This guide is intended as a supplement to other standards, and to federal and state regulations, codes, and criteria applicable to the design of equipment intended for hot cell use.
4.2.4 This guide is intended to be generic and applies to a wide range of types and configurations of hot cell equipment and remote viewing systems.
SCOPE
1.1 Intent:
1.1.1 This guide establishes the minimum requirements for viewing systems for remotely operated facilities, including hot cells (shielded cells), used for the processing and handling of nuclear and radioactive materials. The intent of this guide is to aid in the design, selection, installation, modification, fabrication, and quality assurance of remote viewing systems to maximize their usefulness and to minimize equipment failures.
1.1.2 It is intended that this guide record the principles and caveats that experience has shown to be essential to the design, fabrication, installation, maintenance, repair, replacement, and, decontamination and decommissioning of remote viewing equipment capable of meeting the stringent demands of operating, dependably and safely, in a hot cell environment where operator visibility is limited due to the radiation exposure hazards.
1.1.3 This guide is intended to apply to methods of remote viewing for nuclear applications but may be applicable to any environment where remote operational viewing is desirable.
1.2 Applicability:
1.2.1 This guide applies to, but is not limited to, radiation hardened and non-radiation hardened cameras (black- and-white and color), lenses, camera housings and positioners, periscopes, through wall/roof viewing, remotely deployable cameras, crane/robot mounted cameras, endoscope cameras, borescopes, video probes, flexible probes, mirrors, lighting, fiber lighting, and support equipment.
1.2.2 This guide is intended to be applicable to equipment used under one or more of the following conditions:
1.2.2.1 The remote operation facility that contains a significant radiation hazard to man or the environment.
1.2.2.2 The facility equipment can neither be accessed directly for purposes of operation or maintenance, nor can the equipment be viewed directly, for example, without shielding viewing windows, periscopes, or a video monitoring system.
1.2.2.3 The facility can be viewed directly but portions of the views are restricted (for example, the back or underside of objects) or where higher magnification or specialized viewing is beneficial.
1.2.3 The remote viewing equipment may be intended for either long-term application (commonly, in excess of several years) or for short-term usage (for example, troubleshooting). Both types of applications are addressed in sections that follow.
1.2.4 This guide is not intended to cover the detailed design and application of remote handling connectors for services (for example, electrical, instrumentation, video, etc.).
1.2.5 The system of units employed in this guide is the...

environment where remote operational viewing is desirable.
1.2 Applicability:
1.2.1 This guide applies to, but is not limited to, radiation hardened and non-radiation hardened cameras (black- and-white and
color), lenses, camera housings and positioners, periscopes, through wall/roof viewing, remotely deployable cameras, crane/robot
mounted cameras, endoscope cameras, borescopes, video probes, flexible probes, mirrors, lighting, fiber lighting, and support
equipment.
1.2.2 This guide is intended to be applicable to equipment used under one or more of the following conditions:
1.2.2.1 The remote operation facility that contains a significant radiation hazard to man or the environment.
1.2.2.2 The facility equipment can neither be accessed directly for purposes of operation or maintenance, nor can the equipment
be viewed directly, for example, without shielding viewing windows, periscopes, or a video monitoring system.
1.2.2.3 The facility can be viewed directly but portions of the views are restricted (for example, the back or underside of objects)
or where higher magnification or specialized viewing is beneficial.
1.2.3 The remote viewing equipment may be intended for either long-term application (commonly, in excess of several years)
or for short-term usage (for example, troubleshooting). Both types of applications are addressed in sections that follow.
1.2.4 This guide is not intended to cover the detailed design and application of remote handling connectors for services (for
example, electrical, instrumentation, video, etc.).
1.2.5 The system of units employed in this guide is the metric unit, also known as SI Units, which are commonly used for
International Systems, and defined by ASTM/IEEE SI 10, Standard for Use of International System of Units. Some video
parameters use traditional units that are not consistent with SI Units but are used widely across the industry. For example, video
image format is referred to in “inch” units. (See Table 1.)
1.2.6 Lens and lens element measurements are always in millimeter (mm) units, even where SI Units are not in common usage,
as an industry practice. Other SI Units (for example, cm) are rarely used for lenses or lens elements.

1.2.7 Unless otherwise mentioned in this guide radiation exposure refers to gamma energy level in terms of Co exposure, and
radiation per hour or rad/h absorbed radiation dose Gy/h (rad/h) refers to instantaneous raterates and not cumulative values.
1.3 User Caveats:
1.3.1 This guide does not cover radiation shielding windows used for hot cell viewing. They are covered separately under Guide
C1572.
1.3.2 This guide is not a substitute for applied engineering skills, proven practices and experience. Its purpose is to provide
