4.Effective control of the Commercial Grade Item’s dedication documentation.
Dedicated commercial grade items shall not apply to fuel assemblies, control rod assemblies, and reactor coolant pressure boundary components.
Both the Dedication Agency and the Licensee shall be responsible to file Attachment I to report the abnormality of the Dedicated Commercial Grade Item to the Regulatory Authority within one month when defect or unsuitable condition has been found on a Dedicated Commercial Grade Item.
If a deviation or nonconformance is discovered or informed by a qualified supplier, the licensee shall notify the Regulatory Authority within 24 hours and submit a report within 30 days to describe whether the deviation or nonconformance may cause safety hazards.
Technical Evaluation of the Dedicated Commercial Grade Item shall include the following:
1.Confirming that the proper specifications and safety grade which are used for the nuclear grade items in the reactor facilities.
2.Analyzing the failure modes and failure effects of the Commercial Grade Items to the safety function of systems and components / parts of the nuclear grade items.
3.Establishing the Critical Characteristics and test plan for the nuclear grade items based on the failure modes and effects analysis, and evaluating its effects to the monitoring of the structures, systems, and components (SSC) and the in-service inspection and testing program.
