Power plant maintenance is crucial for safety and preserving the longevity of plant assets. Read this guide for an overview of what that maintenance requires and how drones can help. Without the right maintenance procedures key equipment and machinery can fall into disrepair, leading to potentially dangerous situations on site and also to the premature failure of expensive equipment used in generating power.

Given that new construction is incredibly expensive, power plant owners would generally prefer to prolong the life of an existing power plant over building a new plant or adding onto an existing one. The longer a plant can run the more cost-effective it is over time, and maintenance plays a crucial role in maximizing the longevity of a plant. Power plant maintenance is a blanket term that refers not just to the maintenance of assets and equipment but also to routine inspections, installation of equipment, regular reporting, systems integrations and reviews, and scheduled preventative maintenance—all of the work required to help the plant stay active and in good working order from one day to the next.

Power plants convert raw energy sources such as coal, nuclear heat, or wind, into usable power in the form of electricity. A thermal power plant, which is one of the most common types, is a plant that creates power by burning fuel to convert it into electricity. In a typical thermal power plant, fuel is heated to convert water into steam.

The steam is then sent through a turbine connected to an electric generator in order to create electricity. In addition to thermal power plants, which burn fuel to convert water into steam in order to generate power, there are also power plants that convert energy from naturally occurring sources into power:.

Power plants require thorough, well-kept maintenance protocols in order to stay safe and continue regular operations. In power plants there is often one engineer devoted to maintenance, who holds the title Power Plant Maintenance Engineer. The Power Plant Maintenance Engineer is not responsible for doing every single maintenance-related job at the plant—it would be far too much work for one person to do—but is rather the person who helps supervise these jobs and makes sure that they are being done according to relevant industry standards.

At a power plant, keeping up with maintenance is incredibly complex and challenging, but also crucial for safety. If a problem at the plant does not get addressed quickly it could develop into a life-threatening issue. But there is no way that personnel onsite can keep track of the status of each component and asset the plant uses from one minute to the next.

This is why power plants use computerized systems to track the real-time status of their equipment, down to small details, so that nothing slips between the cracks. This integration is also often used for sharing information about security-related issues like fault detection, alarms, and abnormal conditions detected within the plant.

One way to answer this question is to look at the list of items that a Power Plant Maintenance Engineer oversees. One of the most difficult types of inspections that must be conducted regularly at a power plant are inspections of the inside of an asset, like a tank or a boiler.

Conducting these indoor inspections requires inspectors to stand on scaffolding and use flashlights in confined, cramped spaces, exposing themselves to potential harm.

And building the scaffolding can be costly and prolong downtimes, since maintenance workers often need one to two days to construct it and then another one to two days to take it down. Using a drone removes the need for scaffolding at this stage, since it removes the need for a person to enter the confined space in the first place.

Both drones were designed to be collision-tolerant, sitting within a cage that allows the drone to bump into objects without crashing. Here are three ways that drones like the Elios 1 and Elios 2 can help improve power plant maintenance.

Sending a drone into a confined space instead of a person helps keep that person out of potentially dangerous scenarios. This is especially true at nuclear power plants , where the danger is not potential but real. When conducting nuclear power plant inspections, inspectors must often expose themselves to radiation in order to reach the areas of the plant that need to be inspected. In addition, a radiation monitor must accompany inspectors when they are conducting inspections, which means that two people are exposed to radiation every time an inspection occurs.

Using a drone to collect visual data at a nuclear power plant removes the need for human exposure to radiation, allowing inspectors to remain safely outside the tanks and other irradiated areas while the drone enters them to collect visual data on their condition. Using a drone instead of a person to collect visual data can help power plants realize significant savings, often of tens of thousands to hundreds of thousands of dollars.

Because drone inspections are so much cheaper than manual inspections, drones allow companies to increase the frequency of inspections while still realizing significant savings. Over time, increasing the frequency of inspections can help increase the longevity of power plant assets by uncovering potential problems and addressing them earlier than they would be otherwise.

Increased inspections are also good for the environment , studies have shown. Independent consulting group Boiler Room Consulting found that an increase in the frequency of boiler inspections , which was supported by Flyability drones, could potentially reduce CO2 emissions by as much as metric tons a year.

A nuclear power plant is a thermal power station in which the heat source is a nuclear reactor. As is typical of thermal power stations, heat is used to generate steam that drives a steam turbine connected to a generator that produces electricity. Nuclear plants are usually considered to be base load stations since fuel is a small part of the cost of production [3] and because they cannot be easily or quickly dispatched. Their operations, maintenance, and fuel costs are at the low end of the spectrum, making them suitable as base-load power suppliers. However, the cost of proper long term radioactive waste storage is uncertain. Electricity was generated by a nuclear reactor for the first time ever on September 3, , at the X Graphite Reactor in Oak Ridge, Tennessee , US which was the first nuclear power station to power a light bulb.
