D40 Inspection Camera
“We attached the D40 to poles and were maybe 5 to 10 feet from fuel. We used it for serial identification, and we had a drop light on in the core with the D40’s ring light. It was very easy to read the numbers. The D40 is an excellent camera for this application.” – US Nuclear Plant Reactor Engineering Supervisor.
Considered by many to be the golden standard of radiation-resistant cameras, Diakont’s D40 System offers the perfect mix of high resolution, small size, and high radiation tolerance—all characteristics required for precise performance in extreme environments.
Due to its compact diameter of just 1.58″, this camera is perfect for inspecting confined areas like reactor component interiors. Its modular design and range of attachments make it the ideal “utility camera.” With the ability to reconfigure, it supports all types of plant operations and maintenance. This flexibility offers users the highest level of economy and the best value for their investment.

The D40 camera offers an integrated system solution with a camera, processing system, and user interface. Due to its innovative technology and proven reliability, the system has won deserved popularity from nuclear power plant builders, contractors, and operators worldwide. Thousands of systems have been deployed in the United States, Japan, France, Finland, and other countries.
Compact Split-Head Design
Unlike bulkier shielded cameras, the D40’s optimized split-head design makes it exceptionally condensed and naturally radiation resistant. Minimal electronics are inside the camera, as most components are housed in the topside Camera Control Unit (CCU).
Like all of Diakont’s products, the D40 is designed and manufactured to stringent quality standards. All stages of the production cycle go through factory acceptance testing and are verified through Diakont’s ISO 9001 certified Quality Management System. Radiation testing is also required on all components and completed camera systems to ensure the highest quality camera is produced.
In addition to its wide range of standard functions, the D40 incorporates several superior capabilities unmatched in competitor solutions, including:
Smooth 2x analog zoom
Auto Exposure function for automatic image quality enhancement
Stabilized radial viewing
Ease of maintenance
Its small size, and intuitive design make it easy to use in water and air environments, as it is perfect for accessing tight spaces. The operator can perform axial, lateral, and circular scanning utilizing a range of lenses and attachments. During inspections, the camera is “puppeteered” into position, allowing it to access hard-to-reach locations thanks to its cable; it can also be maneuvered with the pan/tilt or a robotic manipulator. Common applications include:
IVVI of BWR reactor internals
PWR MRP Reactor Vessel inspections
Control rod blade inspection while within the loaded reactor core
Inspection of irradiated fuel cladding
Below-core plate FOSAR operations
Spent fuel cask loading operations
Decontamination and decommissioning activity surveillance
Hot cell surveillance
Pan & Tilt
Diakont’s D40 Camera easily integrates with an off-the-shelf pan and tilt attachment, and auxiliary lighting. Designed for high radiation environments, this system is available with an optional Integrated Console.
Unrivaled clarity: High-rad, precision imaging to perform critical inspections including core verification and gap analysis
Proven technology: Based on Diakont’s D40 rad-tolerant camera systems
Dimmable lighting: Integrated high-intensity lights laterally positioned to provide even lighting and maximize image quality
Versatile functionality: Pan, tilt, and zoom functions
With its unparalleled, seamless maintenance, the D40 replacement tubes and tuning boards are paired at the factory and pre-tuned prior to shipment. This feature supports “plug and play” tube replacement, eliminating labor-intensive field tuning requirements and ultimately saving hours of camera tuning per tube change.
For applications with extremely high gamma fields, the D40 is available with an ultra-rad tube with a 3*10<sup>6</sup> Rads/hr dose rate. These applications include control blade inspections, irradiated fuel assembly inspections, in-air reactor vessel/internals inspections, and more.
The D40 has an optional hand-held remote-control console to plug into the CCU for remote operation. Through a connection of network interfaces, it is operated outside the contaminated area. This accessory is ideal for operators that mount the CCU and want to avoid standing next to the rack to control the camera functions.
An On-Screen Display (OSD) measurement module is also available for the D40, providing distance to target measurements. The OSD module provides a scaled screen grid, allowing operators to measure the size of objects. It also enables operators to annotate screen-captured images providing a permanent record for future evaluation and analysis.
Diakont’s D40 console system incorporates the best-in-class D40 rad-hardened camera, rack-mounted camera control unit, monitor, digital video recorder (DVR), microphone, and microphone hand-held remote controller. All in one rugged enclosure.
It also provides a tiltable monitor to view live footage easily. Video and audio are recorded through the console’s DVR and microphone, then backed up to USB or DVD storage devices. Combining the D40 camera with the equipment required for visual inspections makes the D40 console a turnkey solution, ready to use “out of the box.”
