IGALL actions in reference to EQ 1. Introduction to EQ according IAEA standards. 1. EQ in IAEA requirements (already presented by Alex) 2. SSG-69 main aspects (already presented by Alex) 3. EQ IGALL related documents before phase 5 2. Tasks in IGALL phase 5 and ongoing: 1. Identification of relevant Mechanical and Civil items for EQ. 2. AMP221 modification (minors). 3. TLAA 201 modification(Large) 4. Future work “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 20
SSG 69 (recently published ) • Equipment in scope – Electrical, instrumentation and controls, electromechanical, active mechanical. – Installation features associated with this equipment (e.g. connectors, penetrations, seals, mounting equipment). – Materials of construction which could affect the performance of this equipment including containment wall paint and piping insulation. • Equipment out of scope – Piping, structures and other passive components because their qualification (safety status) is achieved directly by design, construction, inspection and testing according to “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 21
EQ related document before phase 5 • AMP 221: ENVIRONMENTAL QUALIFICATION RE-ASSESSMENT OF ELECTRICAL AND I&C EQUIPMENT – Result of the fusion of previous AMPs (“American approach” + “French approach”) 207+209=221 (¿?) – Strongly influenced in IEC/IEEE 60780-323 standard on Equipment Qualification. – Focus on Reassessment of qualification. • TLAA 201 Environmental Qualification of Electrical and I&C Equipment. – Based on GALL TLAA – Contribution on appendix A from others MS. • AMP 210 CONDITION MONITORING OF ELECTRICAL AND I&C CABLES SUBJECT TO EQUIPMENT QUALIFICATION REQUIREMENTS “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 22
EQ related tasks during phase 5 1. Identification of relevant Mechanical and Civil items for EQ. 2. Update of AMP 221: Transition from Environmental to Equipment Qualification 3. Update of TLAA 201: Transition to Equipment Qualification 4. Development of: AMP 225 Condition Monitoring of Environmentally Qualified Electrical Penetration Assemblies (Version 2021) “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 23
Identification of relevant Mechanical and Civil items for EQ. • A methodology was developed and discussed for identification of mechanical components and civil /structures which might be relevant for qualification. • This methodology was applied and missing lines in AMR table were identified. • After discussion it was decided to refer to TLAA 201 in the AMR lines and incorporate M&C items in the scope of TLAA 201 “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 24
Identification of relevant Mechanical and Civil items for EQ. All AMPs, sections “Programme description” “Scope” Does it include Does it include Equipment with active EQ I&C replaceable and/or components with Electrical time dependent equipment? ARDM? (i.e. thermal aging, radiation ageing) i.e. the scope of AMP143 (Safety-related Valves) i.e. AMP142 includes MOV actuator, CANDU/PHWR Fuel limit switch, etc. List of relevant Handling. Sealing and AMPs hose shall perform the safety function of cooling a spent fuel inside the refueling machine “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 25
Identification of relevant Mechanical and Civil items for EQ. List of relevant Lines on AMR AMPs table Findings: Seals were missing. AMR -Pumps lines were modified -Valves accordingly -Fuel handling system (PHWR) Oil (Snubber) New lines were created in Coating service level 1 AMR lines. “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 26
AMP221 update Considering AMP221 is based on Equipment Qualification Standard and that was reached by consensus the objective was to minimize changes, that is -Transition between Environmental Qualification to Equipment Qualification. -Incorporate mechanical and civil components in AMP221 minimum …some MS are required to include life limited mechanical and/or civil structures, systems or components (SSCs)… Life limiting condition is normally associated with material susceptibility to radiation and/or thermal ageing… seals qualified as pressure boundaries, or protective coatings qualified to prevent severe delamination… If these SSCs are in-scope a qualification re-assessment may be completed using the guidance contained within this AMP … qualification re-assessment usually involves assessments of the environmental effects on the life limiting items such as polymeric/elastomeric seals, gaskets or coatings… -Incorporate EPRI references “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 27
Major changes in TLAA 201 • Complete scope of equipment qualification (three pillars of qualification: Environmental, induced vibrations (seismic APC, etc.) and electromagnetic disturbances. • Scope sections includes a brief methodology for including equipment into TLAA regarding vibrations occurrences (SSE+APC(*)) and/or TLAA regarding accident conditions. • Electromechanical equipment will be handled under this TLAA201 even if it might be assigned to the active mechanical equipment as pumps or valves. • Also consumable components and materials of which shall be assessed regarding environmental effects (i.e. thermal and radiation aging susceptible) are included. Mention to polymeric coating, civil seals, etc. (*)SSE: Safe Shutdown Earthquake APC: airplane crash “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 28
Major changes in TLAA 201 (cont..) • Appendix A Guidelines for the accelerated ageing testing for establishing qualified life was modified. Tables containing values of activation energies have been taken out since numbers without explanation and background might be misleading. Consideration for use of Ea and references are provided. • Appendix B Practical Considerations of Thermal and Radiation Ageing was included in order to expand information on: aging models; multiple material aging and references to material data DB. • Two more appendix (C and D) were added – Appendix C provide example of Finite Element Method used for detailed calculation of operational condition in the context of qualification – Appendix D gathered and provide guidance on data needed for initial qualification and/or when applying qualification assessment methods (*). In particular required data is assigned to qualification assessment in a table format. (*) 1) Using conservatism, Method 2) Type test on aged samples from the plant, Method 3) Performing type test for longer qualified life and Method 4) Component replacement “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 29
Tasks ongoing in phase 6 • When the analysis and review of comments from MS of AMP 221 and TLAA 201 were performed two main concern about consistency and clarity of the documents were identified. – Both document complement each other most of the time in an implicit form – It was not clear why the reassessment of qualification was considered an AMP while Qualification can be assume to be a TLAA. • During Consultancy Meeting (October 2021) previous proposal of future work for phase 6 focused on consolidation and consistency between of AMP221 and TLAA 201 was extensively discussed. A new approach was developed. “Equipment Qualification in Nuclear Installations” 2nd International Meeting, 23 – 26 May 2022, Řež, Czech Republic 30
