Chemistry Products and Services

Depending on numerous factors such as material concept, water chemistry or operational practices, a certain amount of metal oxides and impurities are generated or transported into the circuits of nuclear power plants (NPPs). In order to reduce dose rate build-up and to maintain the component integrity, certain measures (e.g. decontamination, chemical or mechanical cleaning) might become necessary to avoid undesired conditions. Out of specification conditions (e.g. impurity ingress caused by condenser leakage, spent fuel pool leakage due to corrosion) require, beside the elimination of the actual root cause, assessment of the situation regarding possible long-term issues and mitigation consulting.

AREVA NP provides the full set of services around chemistry-related topics throughout the whole plant life cycle, ranging from planning and commissioning via operation to decommissioning. All services, from offsite consulting and analysis services in AREVA NP laboratories to on-site service applications and technical support missions, are always dedicated and tailored to satisfy all individual customer needs and requirements.

The worldwide knowledge and experience as plant manufacturer covers various types of nuclear plants – boiling water reactors (BWRs), pressurized water reactors (PWRs) and also heavy water reactors. AREVA NP teams are supporting worldwide operators of plants of many manufactures (e.g. Westinghouse, Generel Electric, Mitsubishi Heavy Industries, Framatome, Toshiba, Siemens / KWU) with chemistry consulting and service missions since more than 40 years.
