Head of Nuclear
The planned surge in new electricity power generation plant and refits across the world brings with it a demand for improvements in welding technology. This demand will be met by innovative developments in welding equipment to ensure consistently better quality joints, many of which are in the safety critical class.
All the programmes involve extensive fabrication of high-pressure steel pipes and tubes, the welding of which presents particular challenges.
The high pressures and temperatures used in steam generation circuits necessitate the use of creep resistant steels such as those based on chromium/ molybdenum/ vanadium alloys. These materials provide improved oxidation and corrosion resistance together with high strength and are widely used in both fossil fuel and nuclear power plants.
The demand for quality in all these safety critical joints is reflected in the stringent regulations laid down in welding procedures. Nevertheless, some welding practices can result in significant reduction both in corrosion resistance and mechanical strength.
Welding of high-pressure steam pipe
Some engineering alloys are prone to cracking during welding. Industry sectors having to overcome this problem are principally in the power generation sector and include low and medium alloy steels that have been specially developed for their high strength. Metallurgists have learned that heating the joint prior to and after welding (pre-heating and post-heating) can reduce the sensitivity to cracking quite significantly. It involves temperatures in the region of 200°C although this may be much higher for certain materials 3, 4, 5, 6.
Welding is one process that is widely used during manufacture. This affects the microstructure. Preheating, maintaining inter-pass temperatures, and post-weld heat treatment procedures are very critical for these creep resistant alloys. Failure to follow the procedures can result in catastrophic failures in service.
The preferred welding procedures in this type of fabrication are GTAW and GMAW and these offer protection of the exposed upper fusion zone. The joint around the underbead however needs to be protected by purging – the protection of exposed metal by applying a local inert gas atmosphere.
Meeting the requirements of inert gas purging when temperatures exceeding 200ºC are involved necessitates the use of purge systems capable of withstanding these temperatures throughout the heating and welding cycles. Typical thermal cycles can exceed 2 hours and it may be necessary to maintain the purge system in place throughout.
Purging system requirements
Specially engineered purge products have been designed over the past five years that are capable of withstanding the temperatures involved whilst at the same time maintaining adequate gas sealing characteristics. They are also rugged enough to survive multiple-use applications. These products are manufactured from thermally stable engineering polymers and can be provided with advanced gas valve control systems.
Few manufacturers are able to supply weld purging systems that can be used at the high temperatures prevailing during pre- and post-heating but some commercially available systems have been designed specifically to meet the requirements (Fig 1).
However, it is clear that many companies still employ paper, cardboard and polystyrene foam as dam materials. These are prone to outgassing during use, they are difficult to insert and remove and may even ignite at the prevailing temperatures.
FIG 1 Hotpurge® 7 systems cover the diameter range from 150 to 2440 mm. These systems are capable of withstanding temperatures up to 300°C for 24 hours. The inflatable seals are manufactured from flexible, thermally resistant engineering polymers.
Weld Purging Techniques
The most effective devices are those based on connected inflatable dams
The inert gas input can be programmed to control gas flow and pressure during inflation and purging and once placed in position require little more input from an operator. The dams are fabricated using advanced engineering polymers and are thus suitable for use where elimination of contamination is essential.
FIG 2 Example of the PurgElite® 7 range of fully integrated systems covering the 25 to 250 mm pipe range. Complementary systems are available covering the diameter range between 150 and 2440 mm.
Purge gas oxygen content can be controlled by using an oxygen monitor. These instruments not only measure oxygen levels but can inhibit welding if the level is above that set by the operator. Recording and analysing software provides information for quality control purposes.
Even very low oxygen concentrations in weld gases can give rise to discolouration, loss of corrosion resistance and reduction in mechanical strength. Controlling oxygen level in purge gas can be effected simply and efficiently using contemporary integrated purge systems.
FIG 3 Oxygen monitor designed specifically for use in a welding environment. The PurgEye® 7 range is capable of measuring residual oxygen content down to 10 ppm.
The UK Government is looking for businesses who can support in the supply of ventilators and ventilator components across the UK as part of our response to COVID-19.
There is a requirement for Design, Manufacture and Supply of the following medical devices or component parts :
As well as manufacturers, they are looking for businesses with the following skills:
Vessco Engineering Ltd is a featured Tier 2 Supplier to HPC. Vessco is just one of an increasing number of Wales based companies supplying the Hinkley Point C nuclear new build project. EDF have produced a supply chain map which indicates that 100 Welsh companies already supply goods and services to HPC.
WNF is dedicated to increasing both the number of Wales based suppliers to HPC and the total value of contacts.
Vessco Engineering started approaching EDF, Alstom Power Systems and Rolls-Royce in 2010 just as the UK Government was contemplating a resurgence of new build activity in the new build nuclear sector. This culminated in civil nuclear approved supplier status for both Alstom and Rolls-Royce in 2012. As the parties stuttered towards a final investment decision in 2017 Vessco Engineering alongside hundreds of companies throughout the UK continued to make overtures to the prospective Tier One suppliers to HPC and EDF directly. The Wales Nuclear Forum was formed during that period with the aim of galvanising a sustained effort by Wales based businesses to gain contracts at HPC and prospective sites at Wylfa and NuGen in Cumbria.
The disappointing news regarding postponement at Wylfa and abandonment of the NuGen proposals at the end of 2018 / early 2019 cast a shadow over the civil nuclear resurgence in the UK. However, the development at HPC is now in full swing and advanced plans exist for new sites at Sizewell in Suffolk and Bradwell, Essex. There is still time for WNF members to gain new business at HPC and everything to push for at SZC and Bradwell B.
Vessco Engineering gained its first multi-million pound contract for GE in December 2017, this was followed by contracts with Ovivo UK Ltd and Balfour Beatty. Vessco’s workforce numbers and turnover have more than doubled since its involvement in nuclear new build and future prospects are encouraging.
Within Wales the civil nuclear sector activity is centred on decommissioning at Trawsfynydd and Wylfa and plans for small modular reactors particularly at Traws. There are currently around 1,500 people working in the civil nuclear sector in Wales.
In light of growing concerns about Coronavirus, the WNF Steering Group has taken the decision to postpone the event planned for the 19th of March. The meeting will instead take place on Thursday 21st of May at Wrexham Glyndŵr University.
More details will be issued very soon.
If you have registered to attend the event we will carry forward your registration to May 21st but if for any reason you are unable to attend the rearranged date, let us know. Similarly, if you have booked an exhibition stand this will also be carried forward to the next event. Again, please let us know if you do not wish us to do that.
We apologise for any inconvenience and thank you very much for your understanding.
The United Kingdom is a pioneer of nuclear technologies and opened the world’s first commercial nuclear power station in 1956, at Calder Hall near Sellafield in Cumbria. Nuclear power has delivered great benefits: it has supported national defence, generated electricity for more than 60 years and our country remains a world-leading nuclear enterprise.
Today the UK is faced with the challenge of cleaning up the legacy of its early nuclear operations – a large-scale programme undertaken by the Nuclear Decommissioning Authority (NDA). This includes delivering innovative solutions for managing radioactive waste that meet today’s safety standards and will protect us into the distant future.
UK Government policy is to have a wide mix of energy supplies, so we use nuclear alongside other energy sources, such as gas and solar. Today, nuclear energy generates around one fifth of the country’s electricity, and under current government proposals that include Hinkley Point C, some of our power will come from nuclear sources in the future.
There are important reasons why nuclear is part of the mix:
it’s a low carbon choice that supports the UK’s climate change goals: nuclear power stations generate electricity without emitting greenhouse gases like carbon dioxide and methane
nuclear power plants produce electricity 24 hours a day, whatever the weather
nuclear power plants don’t require a daily supply of new fuel to operate, unlike gas, coal and biomass plant

By 2050, we need to have a net zero carbon economy, to protect our environment for future generations. That means we need to generate much more energy from low carbon sources.
But we also need a reliable, home-grown source of power, especially as electricity will power heat and transport.
And our energy systems needs to create prosperity across the UK, offering life-changing opportunities to tens of thousands of people.
Nuclear energy is a low carbon, reliable, home-grown supply of power. The sector creates high quality direct and indirect employment for around 155,000 people.
It’s time to Rediscover Nuclear.
