For years reactor vessel inspections have relied on two separate viewing systems...one equipped with a color CCD camera (i.e. SC-18) with zoom capability for close-up viewing in low to moderate radiation areas, and a second equipped with a radiation tolerant camera (i.e. RTC-3) for close-up viewing in high radiation areas. All control, video and power signals are sent over a single cable (CA-75-XXX).

The CVS is a revolutionary development in integrated viewing systems that completely eliminates the need for for two separate systems.

The optional components are:

The SC-18 (Shielded Camera) video inpection system is comprised of two main assemblies, an underwater assembly and a surface control console connected together by a single cable (CA-73-XXX). The underwater elements of the system include a shielded camera, a miniature pan & tilt unit, and a set of two compact 75-watt lamps. The camera utilizes a high resolution, SuperHAD image sensor coupled to a miniature 18:1 zoom lens. Metal shielding allows for closer and longer viewing while operating the camera in a high radiation environment. The camera housing is constructed of stainless steel. The PT-5 pan & tilt unit and WDL-75 lamp housings are constructed of hard anodized aluminum. All underwater equipment is depth rated to 30 meters, (100 feet). The control unit is the main surface element of the SC-18, providing power and facilities for controlling the underwater equipment.

The SC-18 has been field proven by various nuclear service companies and the nuclear utility groups in both PWR and BWR reactor vessels for general video inspections requiring a by the Nuclear Service Companies and Nuclear Utilities. The SC-18 is a cornerstone to the Convertible Viewing System (CVS) and can also be used as a stand-alone camera where confined spaces limit the use of a complete video inspection system.

This advanced Fuel Identification System or FIDS produces high definition images despite thermal distortion, radiation effects, suspended particles or corrosion.

The FIDS pan and tilt, incandescent light and RAD hardened strobes are field proven and dependable underwater components. They give you excellent performance and precise control when linked to our specially designed controller unit. Adjusting camera orientation and lighting is intuitive and responsive. The radiation tolerant CCD camera, or optional RAD hardened camera, provide quality images when core mapping, performing inspections on fuel bundles or locating foreign objects.

The Bowtech BP-CVIS-II, Compact Video Inspection System, is a portable control station for operation, viewing and recording of color or monochrome video cameras together with audio input and intensity control of a lamp.

This BP-CVIS-II model comprises of a Digital Hi8 VCR which produces noiseless digital images, even when playback is frozen, it features a 100th/sec tape counter, it has a built in Video Overlay with Date & Time Generator and also a digital zoom facility, a 15" color TFT LCD Monitor, audio input, a dimmer circuit, video and audio output enable connection straight into a separate monitor etc.

This entire system is housed in a watertight “Storm” case measuring just 490mm in width & 400mm in depth and only weighs 10Kg (umbilical and peripherals are extra). It can be powered from 240VAC or 120VAC mains or from 12VDC.
