The pressure transmitter

You're probably wondering why we use nuclear-qualified pressure transmitters .

One of the right questions to ask is: Safety?

What makes them so special?

We're going to take you through the essentials right now.

So what exactly is a pressure transmitter ?

what is a nuclear pressure transmitter

Fuji Electric sensors are designed and manufactured for accurate and reliable measurement in nuclear facilities.

They are qualified for installation in systems with safety-related functions, whose failure could have serious industrial or radiological consequences.

Fuji Electric's nuclear pressure transmitters have been installed for several decades throughout EDF's French nuclear fleet and in many other power plants around the world, as well as in the latest EPRs commissioned or under construction (Taishan, Flamanville, Olkiluoto and Hinkley Point).

Fuji Electric France's total commitment to nuclear safety includes the implementation of a safety culture approach. It's part of the company's DNA.

Nuclear qualifications, IEEE, RCC-E K3, K3ad, KTA, IEC... are you familiar with them?

nuclear qualifications iee rcc e k3 k3ad kta

The RCC-E provides rules for the design and construction of electrical and control systems for pressurized water reactors.

It defines the technical rules and requirements for :

Qualification of equipment subject to safety classification (IPS-1E / F1A / NC) and equipment important to plant availability (IPD),
Specific quality assurance regulations, supplementing ISO 9001.

The RCC-E is drafted by AFCEN (French Association for Design Rules): https://www.afcen.com/fr/rcc-e/187-rcc-e.html

It is developed in partnership with manufacturers, engineering firms, manufacturers, regulatory bodies, and operators, and represents a collection of best practices in accordance with IAEA requirements. AFCEN's members include companies and institutes such as EDF, Framatome, CEA, Bureau Veritas, etc.

Fuji Electric pressure transmitters are qualified according to RCC-E.

There are several qualification categories:

Qualification under normal ambient conditions according to RCC-E (unclassified safety category: IPS-NC)
Qualification for accidental conditions for instruments installed on safety-classified functions: These qualification procedures (RCC-E volume B) are used to demonstrate the suitability of our category K3 and K3ad instruments for use in specific and/or accidental environmental conditions.

Why choose a Fuji Electric nuclear-qualified pressure transmitter ?

Choosing a Fuji Electric "nuclear-qualified" transmitter ensures that you will meet your project requirements in terms of:

Safety classifications
RCC-E qualifications: NC, TAS, K3 or K3ad
Ambient family & accidental thermodynamic profile
I&C safety criteria
Integrity or operability under seismic loads in accidental conditions accidental conditions
Manufacturing traceability
Our ISO 9001, QN100/QN200/QN300 and, more recently, ISO19443-certified quality management system ensures the conformity of our products.
Guaranteed supply of documentary deliverables according to project specifications.
Adherence to the project schedule through rigorous management and monitoring by a dedicated nuclear project team.

6 essential features of a nuclear pressure transmitter :

A nuclear pressure transmitter is built using materials from rigorously selected suppliers, ensuring the high level of quality, traceability and qualification required. Discover 6 essential criteria for ensuring safety with a nuclear pressure transmitter .

quality approach

QUALITY APPROACH :

Fuji Electric ensures strict quality control during the manufacturing process, including ongoing training and skills management for personnel, traceability of supplies and third-party suppliers, control of manufacturing processes, documentation, and technical support for customers.

LIFETIME

LIFETIME :

Fuji Electric's nuclear pressure transmitters have been qualified to ensure their function and maintain their level of qualification, i.e. maintain their level of performance and operability in the event of a serious accident, for a period of 40 years, and even 60 years for some of them.

connectors

CONNECTORS :

Electrical connections are also a key point. For example, we use K2-qualified, quick disconnect 1/4-turn subbases from partners such as SAIB and SOURIAU, themselves long-established players in the French nuclear industry.

seals

THE JOINTS :

All our gaskets and seals are PMUC-certified.
Depending on the type of transmitter and its intended use, e.g. a radiologically demanding area, we offer EPDM gaskets for their high tolerance to irradiation.

electronics

ELECTRONICS:

The various types of electronics are specially designed to ensure performance and reliability.

The "smart" digital models have undergone rigorous robustness tests, while the "analog" models, without any programmable digital components, guarantee performance and reliability in the most demanding environments (accidental profiles, irradiation, earthquakes & thermodynamic shocks).

process connection

PROCESS CONNECTION :

In addition to the classic process flange connections, diaphragm seals versions are also available, offering a wide range of connections options:

Mounting with flange adapter to EN or ANSI standard
OD 3/8 weld-in tube mounting
Flushing rings

They are also distinguished by their choice of materials, depending on the nature of the process fluid: 316L stainless steel, Hastelloy C (for seawater applications), membrane with gold+ceramic coatingpressure transmitter for hydrogen applications), etc.

Pressure transmitter nucléaire : How to choose?

Fuji Electric's range of nuclear-qualified pressure transmitter covers a wide range of applications:

pressure transmitter a separateur a membrane

"Category K3-AD" classified or unclassified
Pressure transmitter with diaphragm seal
digital or analoggauge pressure or differential)

pressure transmitter analog or digital

"Category K3-A, K3-AD "Classified or unclassified
Digital or analogPressure transmitter (absolute, relative or differential pressure)

The entire Fuji Electric range can also be supplied with diaphragm seals . The selection is based on:

Ambient conditions?	No irradiation, or Presence of ambient and/or accidental irradiation up to 50 kGy
Need to qualify for accidental conditions?	NC TAS K3 K3ad
Seismic requirements?	Operability Integrity Dimensioning spectrum
Service conditions ?	Temperature Pressure Type of fluid and risk of corrosion
, two main families can be distinguished of devices that can meet the majority of applications:	"smart" digital transmitter Transmitter with 100% analog electronics containing no programmable components (CEP or ANFL)

Where are Fuji Electric pressure transmitters installed?

The applications are numerous and varied.

pressure transmitters Electric pressure transmitters are used in almost all areas of a nuclear power plant, except for the containment building. They are used in the secondary circuit, the cooling circuit, and in the machine room that houses the steam turbine. They are also installed in auxiliary circuits and backup circuits:

Chemical and volumetric reactor control (RCV)
Safety injection ratio (RIS)
Emergency water supply for steam generators (ASG)
Intermediate refrigeration (RRI)
Raw water backup (SEC)
Refrigeration and purification of swimming pool water (PTR)
Ventilation
