Engineering Design of Nuclear Power Plants.

The engineering design of a nuclear power plant needs to consider specific site characteristics, operational aspects and future decommissioning plans so as to achieve the highest levels of safety. A comprehensive and thorough safety assessment is key to ensure the adequate protection of workers, the public, and the environment.

The objective of engineering design is to provide for the safe and effective operation of the nuclear power plant, minimising the likelihood of accidents and ensuring that their consequences can be reliably mitigated.

The primary means to achieve this is the ‘defence in depth’ approach, consisting in the implementation of consecutive and independent levels of protection. In relation to engineering design, the safety provisions of the ‘defence in depth’ approach include: an adequate design for the site characteristics, multiple physical barriers to the release of radioactivity, and the application of strong safety requirements and proven engineering practices to ensure adequate safety margins and a high reliability of design features that preserve the integrity of these barriers.

This is achieved mainly by the use of technology and materials of high quality, control, surveillance and protection systems, and an appropriate combination of inherent safety features and engineered safety systems. These items must also meet stringent requirements for withstanding internal and external hazards, redundancy and diversity, as appropriate. The ‘defence in depth’ approach also relies on effective management systems.

The safety of the plant needs to be demonstrated throughout all stages of its entire lifetime, in particular before the loading of the nuclear fuel and the beginning of operation. A comprehensive safety assessment, including a deterministic and probabilistic safety analyses for internal accidents and external events, needs to be carried out to ensure that all safety requirements established for the design are met and are in accordance with relevant national and international codes and standards, laws, and regulations.

The engineering designs of nuclear power plants are constantly undergoing a process of improvement and modernisation; hence all designs must allow for design changes and modernization.

Solar Energy

Solar power is the generation of electricity from sunlight.

Concentrated solar power (CSP) systems are systems that use mirrors or lenses to focus a large area of sunlight onto a small area. Electricity is produced when solar energy is converted into heat, which drives a heat engine connected to an electricity generator. Concentrated solar power plants are used to power the electrical grid.

Concentrated solar power plants come in various types, i.e. parabolic dishes, solar power towers, and parabolic troughs.

The CSP plant primarily comprises of four subsystems as summarized below;

Then we will provide drilling and wellfield design, reservoir engineering, field testing, and general project development and strategies.

Biogas Energy

Biogas is a fuel produced by the degradation of organic matter by microorganisms in the absence of oxygen and consists of the breakdown of substances contained in plants, sludge, and animal by-products. Biogas systems turn waste into a resource.

Biogas systems make it possible to produce biogas from;

Agricultural biomass (corn, sorghum, sunflower, straw, cereal flour, agricultural waste in general),
Livestock manure (cattle slurry, cattle manure, pig slurry, goat manure, sheep manure, poultry manure,
Other biomass produced from processing waste (sewage sludge, fruit and vegetable residues, agro-food residues, table scraps, slaughterhouse waste, fish processing residues, blood, serum).

Biogas and Biomethane.

The different biogas plants are distinguished according to the matrix used i.e. from livestock manure and/or agricultural biomass, or from the organic fraction from waste. All biomethane and biogas plants must be carefully designed to ensure high safety, high reliability, and low management costs.

Biogas can be refined and purified for production of biomethane (99% methane) which has conditions and characteristics of use corresponding to those of methane, can be stored, transported or placed in the natural gas network. The different biogas plants are distinguished according to the matrix used i.e. from zootechnical waste or agricultural biomass, or from the organic waste fraction.

The production of electricity and heat from biomass represents a new and high source of income, thanks to the ever-increasing need for energy from renewable sources. The energy produced is considered green energy because it is produced with low environmental impact.

The main types of biogas digester technologies for small to medium sized units are fixed dome, floating dome, and tubular polybag. The technology for large sized biogas digesters is a concrete active bioreactor with balloon gas holders.

Common types of biogas digesters.

The most common types of biogas digester technologies are briefly described below. They are categorised as continuous wet digestion systems. This means they operate with daily input of fresh feedstock (“continuous”) into the same active bioreactor volume and are fed with a feedstock with high water content or by adding water. The waste material is a slurry and flows like a fluid material. The active bioreactor is always full (steady state system). In other words when fresh material enters the active bioreactor, digestate leaves the active bioreactor.

A fixed-dome plant includes a cylindrical rigid active bioreactor with a rigid gas-holder dome, a feedstock inlet, and an outlet area also called expansion chamber. The gas produced in the digester is stored in the upper part of the unit (in the gas holder dome). With a closed outlet gas valve, gas pressure inside the dome increases with time, pushing the digestate into the expansion chamber. When the gas valve is open for gas utilisation, gas pressure drops, and a proportional amount of slurry flows back from the expansion chamber into the active bioreactor. Typically, such a biogas unit is constructed underground, protecting the active bioreactor from low temperatures at night and during cold seasons. Given that the gasholder dome undergoes pressure, this system needs experienced and skilled construction to ensure gas tightness. Also, given its underground construction, it should be considered as permanent infrastructure.

A floating-drum biogas plant consists of a cylindrical active bioreactor and a movable, floating gasholder (drum). The produced gas collects in the gas drum, which rises or falls again, depending on the amount of gas produced and used. The rising and falling drum, thus, provides a helpful visual indicator of the gas production and available gas quantity. The weight of the gas drum creates gas pressure. To increase gas pressure, weights can be added on top of the gasholder.

A tubular polybag digester consists of a longitudinal shaped heat-sealed, weather resistant plastic or rubber bag that serves as an active bioreactor and gas holder. The gas is stored in the upper part of the bag, and the inlet and outlet are attached directly to the bag at each end. As a result of the longitudinal shape, no short-circuiting occurs and slurry flows through the biogas unit in a plug-flow manner. Gas pressure can be increased by placing weights on the bag while taking care not to damage it. The benefit of this technology is that it can be constructed at low cost by standardised prefabrication. However, the plastic balloon is quite fragile and susceptible to mechanical damage and has a relatively short life span of 2-5 years. To avoid damage to and deterioration of the bag, it is also important to protect the bag from direct solar radiation with a roof. Additionally, it is recommended that a wire-mesh fence protect it against damage by animals.

Concrete digesters with balloon gasholders are typically used for large scale systems, although the technologies described above can also be used for large units. Concrete and balloon designs are typically aboveground and have different units serving different purposes. With this technology, mixing pits are often an additional component. These allow feedstocks to be mixed and homogenised before they are fed into the digester. The mixing pits are equipped with propellers for mixing and/or chopping the feedstock and often a pump is used to transport the feedstock into the digester. The active bioreactor itself is made of concrete or steel and often insulated. Large active bioreactors are almost always stirred by slow rotating paddles, rotors, or injected biogas. The gas holder is usually made of flexible material. It can be placed either directly above the active bioreactor to act as a balloon plant or in a separate ‘gas-bag’.

Thermal Power

While the world moves towards renewable sources of energy, thermal power generation still plays an important role, often being used in conjunction with renewables. The design of thermal power plants (TPP) requires the participation of a multidisciplinary team of electrical engineers, architects, civil engineers, ecologists, etc.

Our team has extensive experience in many aspects of thermal power stations, including environmental protection, fly ash disposal, heavy machinery foundations, chimney stacks, and major engineering structures such as boiler houses. Thermal power plants can utilize different types of fuel, i.e. coal, fuel oil, or natural gas. Coal is considered a more affordable and economically viable fuel. However, it has serious disadvantages associated with the environmental impact of the process and its effectiveness. In each case, an individual approach is needed. Coal fired thermal power plants release huge amounts of fly ash, a waste that is very detrimental to the environment.

Energy Audits

In recent times, energy efficiency has become very paramount, both in building systems, production plants, and numerous energy consuming operations. An energy audit is an energy efficiency study or inspection survey and analysis of energy flows for energy conservation in a building, factory, or other system. It entails critical study of equipment, processes, and operations with the objective of identifying energy saving opportunities that can help reduce the energy bills of a production plant without impacting production volumes, quality, or safety. Energy audits are planned and conducted as part of the identification and prioritization of opportunities to improve energy performance, reduce energy waste, and obtain related environmental benefits.

During energy audits, we undertake comprehensive study and inspection of various system components, among them electrical systems, lighting systems, pumps, motors, HVAC systems, and SCADA, automation, and control systems. Whilst undertaking energy audits, we conduct condition monitoring of equipment, site survey of energy consumption, identification of major energy utilization equipment, identification of minor snags in the system, assessment of energy saving measures, and an evaluation of operational controls.

An energy audit will show which processes require energy and in what quantities. The next step is to implement active and passive energy efficiency measures. Passive measures are defined as easy-to-implement actions, while active measures require significant changes to existing equipment and processes, including expensive automation and optimization. The last step is energy reporting and monitoring, through which the facility or plant operator can set targets for future energy efficiency measures and identify key performance indicators for the implemented measures.

Through our energy audits, we give clients the insights they need to understand their energy use and help them to monitor and control them. Routine undertaking of thorough energy audits helps guide entities on energy optimization in their operations, resulting in significant operational cost savings. Through our energy audit reports, we present every detail about the building or plant facility and its components to the client. Our suggestions detail the effective steps towards implementing a package of improvements to achieve the client’s goals. These goals could include reducing energy consumption, improving comfort throughout a structure, improving indoor air-quality, eliminating health and safety hazards, or even carbon footprint reduction.
