High-quality procurement operations ensure safe, competitive, and reliable production and long-term operation of the plant units.

In supplier selection, particular attention is paid to the continuity of the suppliers’ operations, delivery reliability, quality, environmental management, and competitiveness, while also appreciating domestic and local suppliers. Suppliers are assessed, delivery quality is monitored, and immediate corrective measures are taken when necessary.

TVO only procures products and services from evaluated and approved suppliers. TVO uses a supplier classification system for all its suppliers based on how significant their operations are for TVO’s safety and potential risks contained in its production operations. The products procured must meet TVO’s safety, quality, and environmental requirements. Orders can be placed with assessed suppliers (100%) only.

Suppliers and subcontractors are monitored

TVO observes the legislation that obligates companies ordering construction work to submit to the tax administration information of the site, any subcontracting contracts, the actual invoice, and each employee. The information must be submitted monthly via an online service. Each contractor, including both Finnish and foreign companies, carrying out work in TVO’s facilities must have a valid order or contract. All contractor employees must carry an access card that states a tax number that has been entered in the public tax number register. The reliability and financial status of contractors are regularly monitored. Non-recurring contractors are monitored throughout the delivery process.

According to the Act on the Contractor’s Obligations and Liability when Work is Contracted Out, a contractor must supply the necessary information, no more than three months old, plus any requested appendices and reports. If the employer of an employee or a party to a subcontracting contract is a foreign enterprise, the information corresponding to the documents and certificates listed in the Act on the Contractor’s Obligations and Liability when Work is Contracted Out must be submitted as registry extracts in accordance with the legislation valid in the country in which the enterprise’s registered office is located, as corresponding certificates, or in another generally acceptable manner.

Depending on the nature of the delivery or service, the contracting party must also be acquainted with the YVL Guides. In unclear situations, the contracting party has the obligation to confirm with TVO that national legislation and regulations are interpreted identically, and to ensure that these national requirements are understood and observed even in long subcontracting chains.

Audits – a quality assurance method

TVO requires that contracting parties use operating methods that comply with TVO’s Code of Conduct and company-level policies . TVO’s contractors generally apply a quality level in accordance with the ISO 9001 quality system, ISO 14001 environmental system, and OHSAS 18001 occupational health and safety system. Auditing is one of the quality assurance methods used. The audits may be carried out by TVO or a third party. TVO has the right to audit quality, safety, information security, and environmental systems, as well as the operations of its contractors and subcontractors to the extent it considers necessary. Contractors are obligated to ensure that the above-mentioned right is included in all contracts between the contractor and its subcontractors in the entire delivery chain. The Radiation and Nuclear Safety Authority (STUK) may participate in the audits to validate TVO’s or its contractors’ operations.
