TÜNAŞ and the US's USTDA to assess 4 SMR and 5 fourth-generation reactor designs under a 2 million dollar grant

Türkiye Nuclear Energy Inc. (TÜNAŞ) and the US Trade and Development Agency (USTDA) signed a grant agreement of about 2 million dollars at the Turkish House in New York on 22 September 2026. 4 small modular reactor (SMR) designs and 5 fourth-generation reactor designs from US companies will be assessed over at least 1 year.

NEW YORK

According to an Anadolu Agency report dated 22 September 2026, the agreement was signed by the General Manager of TÜNAŞ and the Deputy Director of USTDA; Energy and Natural Resources Minister Alparslan Bayraktar also attended the ceremony. The study will compare the SMR designs of 4 US companies and 5 different fourth-generation designs from technical, economic, regulatory and licensing perspectives. More than 10 items are listed among the review topics: design features, cost, licensing status, supply chain, SWOT analysis, financing model, permitting framework, emergency protocols, security design and site selection.

As reported by İktibas Dergisi the same day, the grant amount is about 2 million dollars, the duration at least 1 year, and USTDA covers the US-side cost of the technical work. Minister Bayraktar linked the assessment to the 2053 net-zero emissions target and the goal of energy independence; SMRs were presented as a 2nd track to diversify the portfolio alongside large-scale plants. Bayraktar was reported to have also met the Canadian Foreign Minister and AtkinsRéalis management during the same visit; whether any concrete commitment emerged from these meetings could not be verified as of 23 September.

The agreement is not a purchase or construction decision; it is a preliminary study comprising a comparative feasibility assessment of 9 designs. The sources do not state which sites will be examined or whether the study will lead to the selection of a supplier.

Talay assessment

Bottom line

A grant of about 2 million dollars is a small sum, but it is one of the first institutional steps formally putting US technology on the table in Türkiye's nuclear roadmap. No investment decision should be expected before the comparison of 9 designs, lasting at least 1 year, is complete; the real signal is Ankara's intention to open a second, US-sourced track alongside the large-plant model.

Likely effects

  • Türkiye energy diversificationPositive6 months+

    Assessing SMR and fourth-generation designs could turn a single-track plan dependent on large plants into a two-track portfolio for the 2053 net-zero target.

  • Türkiye–US relationsPositive1–6 months

    USTDA covering the cost of the study makes energy a low-cost but visible area of cooperation between Ankara and Washington.

  • Implementation riskNegative1–6 months

    Licensing, financing and site selection are all subjects of the same study; if these items are not clarified, the study could become a feasibility report left on the shelf.

    Uncertainty over financing or the regulatory framework delays the assessment and it falls off the agenda.
