Independent Supervision of the Commissioning

TES company brings its expertize in the field of commissioning of power plants (especially nuclear power plants) providing independent engineering supervision of the commissioning and engineering supervision of the reconstruction and refurbishment of power plants.

Review of specified project documentation

Within the independent supervision of the commissioning of nuclear power plants we provide a review of selected project documentation with focus on nuclear safety issues.

Review of the commissioning documentation

As a part of independent supervision process during the preparation phase of the commissioning, we review the following parts of the commissioning programme:

  • Working programs of non- active and active phases of the commissioning considering their compliance with nuclear safety requirements and testing the safety and   safety- related equipment and system.
  • Testing programmes of separate and integration testing of the safety and safety-related equipment and systems as well as programmes of initial criticality and power tests including dynamic tests.

Assessment of readiness to commissioning stages

During the pre-commissioning period we assess the overall completion of each commissioning stage considering nuclear safety, especially readiness for testing of safety and safety-related systems.

Supervision over the realisation of the commissioning

During the realization phase of the commissioning we provide permanent supervision over each phase . We monitor compliance with nuclear safety requirements and notifiying about possible irregularities or non-compliance.

Independent testing

We provide additional independent measurements, if necessary, especially when non-compliance with the project and safety criteria is indicated.

Verification calculations

In case that non-compliance with the project or safety criteria is assumed we provide verification computational analyses using computer codes approved by regulatory authority.

Review of the test evaluation and commissioning stages

Independently from the entity performing the commissioning we provide review of the test results of each commissioning stage and own tests focusing on the nuclear safety. In substantiated cases we provide our own independent evaluation instead of merely review.

Scientific Supervision of Commissioning

Technical support of the scientific supervision of the commissioning works provided at Temelin NPP ensuring the highest safety level and commissioning procedures quality. Round-the-clock attendance during the active commissioning programme, cooperation in the test results evaluation, independent evaluation of the non-active and active stage of commissioning, recommendations for safety enhancement.
