“Anywhere you need to see but can’t fit your head.” A company slogan from USA Borescopes that reinforces the need for these tools when navigating tight spaces or unreachable spots within the premises. For our discussion we may even modify the tag line to say, ‘Anywhere you need to see but it’s UNSAFE to put your head’
Routine borescope inspections are important for nuclear power plants to conduct. However, they require strict safety protocols and a high level of vigilance in order to keep staff members and the wider community and public safe. Borescopes and industrial videoscopes may help to examine any of the following:
- Containment Structures – Concrete walls and steel liners that surround reactors to prevent radioactive material from leaking out.
- Steam Generators – Systems that transfer heat from the reactor coolant, with the production of producing steam for turbines.
- Fuel Assemblies – Cracking or a change in the formation of the fuel rods can affect reactor power output and cooling efficiency.
- Reactor Pressure Vessels – RPVs hold the nuclear fuel and coolant, making any failure a severe safety risk, so inspections are crucial for this system.
- Control Rods and Drive Mechanism – Inspections that ensure rods are free from wear or deformation.
- Primary and Secondary Coolant Systems – Cracks or leaks in piping or valves that lead to overheating and core damage.
Borescopes range of tools aid in these inspections, which are essential for early detection of any potential problems that are present. Preventative measures that help to avoid catastrophic failures. Video borescopes cater to the challenges that these inspections face whether that’s radiation exposure, time constraints, or access to confined spaces.
Many safety concerns come with nuclear power plants and the risk of radiation exposure. As such, safety standards are incredibly high and there’s no room for error. It’s why regulatory bodies like the Nuclear Regulatory Commission (NRC) implement strict limits on acceptable doses.
The NRC sets the annual effective limit at 5 rem for nuclear plant workers. This is significantly higher than most would receive from natural background radiation, but as such, it is monitored to ensure worker safety at all times.
The ALARA (As Low As Reasonably Achievable) is the guiding framework for radiation safety. The above principle essentially mandates that exposure should be reduced to the lowest possible level. That’s where the use of Borescopes can prove incredibly useful to conduct safe inspections from a distance away from any potential dangers.
This kind of advanced technology enables those inspecting the various items above to avoid direct exposure to hazardous areas in general.
Video borescopes inspect components in high-radiation environments, and with USA Borescopes in general, there are several products available. Each tool offers high-resolution imagery and videos that help monitor and assess the rector components remotely. Enhancing the safety of nuclear inspections is just one of the benefits of using video borescopes.
Perhaps one of the most significant and useful advantages of video borescopes is the capability of performing remote visual inspections. Personnel responsible for inspections can use this technology from a safe place, lowering any potential risk as a result. From RPV to steam generators, individuals can assess areas without entering high-radiation zones.
For example, the USA2000 J-6-7000 videoscope offer HD dual-view insertion probe, providing 7 meters of length for visual inspections done from a distance. It provides real-time visuals that are needed to monitor an area without the need for close contact with radiation sources.
Many of USA Borescopes’ customers benefit from the products due to their easier access to confined spaces. Nuclear reactors are often in complex environments, where many areas are hard to reach manually. From control rod housings to coolant system pipes, video borescopes have flexible insertion tubes to navigate these areas. It can provide a visual assessment clear enough without having to disassemble or disrupt the spaces in general. With minimal disruption, these tools keep the power plants moving along efficiently.
Borescopes help to enhance safety, but they’re also beneficial to accommodate pressing time restraints, which are common in environments and organizations like power plants. Reactor shutdowns in particular are tightly scheduled to minimize the operational downtime.
Video borescopes help to streamline the length of inspections, providing technicians with the ability to quickly assess the critical components necessary. The high-resolution imagery of the borescopes, as well as the option to record video for post-inspection reviews, make them an incredibly helpful tool for ensuring efficient inspections every time.
Nuclear inspections often find evidence of wear and tear, corrosion, and other issues that could compromise the safety of the personnel and the wider area surrounding the plant. The advanced technology used in borescopes allows nuclear plant operators to implement preventative maintenance programs.
After all, it’s better to prevent disasters from happening and to be proactive with anything that’s discovered early on through inspections. For power plants, there’s also a big cost benefit. Helping to reduce long-term maintenance costs can make the business operations more financially savvy.
Circling back to the NRC, inspections using borescope technology help to support regulatory compliance. The NRC requires detail in the documentation of inspections, including that of visual records. The images saved on the borescope also offer a time date stamp which provides data that is required when submitting reports.
Inspectors are able to capture high-quality evidence that can then be stored, analyzed, and referenced if needed in the future. It can also help to keep track of maintenance activities and to track potential problem points down the line. Documentation as detailed as this helps to meet the stringent safety standards that many nuclear plants have to adhere to.
