RSE-M 2017

Changes made in this new edition are particularly concerned with:

BINDER I:

• A 1700: Inclusion of a new chapter on layup of secondary system components (steam generators in particular), especially chemical specifications for layup.

• B 1200 and B 8510: Clarification of the MSS boundaries.

• B 4000: Harmonization of paragraphs in B 4000 which call for a manual liquid penetrant examination technique as part of the ‘defense in depth’ principle (hypothetical defects), with RCC-M MC 4000.

• B 4800 and B 4900: Creation of both chapters B 4800 (examination of piping in the MPS and the MSS) and B 4900 (overall examination of the MPS), considering the evolutions of chapter B 4900 since 2015 and in accordance with the actual practices.

• B 6312 d): The results from an ISP capsule undergo further processing to establish the shift in RTndt when the difference between the measured values TK7 and T0,9 is greater than 8°C.
• B 9000: Creation of a chapter specific to Pre-Service Inspection, which is neither a periodic requalification nor a periodic inspection and update of the text.

BINDER II:

• Appendix 1.1: Addition of definitions.
• Appendix 1.3: Update of the designated edition for RCC-M; addition of AFCEN Technical Publications.
• Appendix 1.4: Update of references to be consistent with RCC-M‘s evolutions.
• Appendix 1.8: Suppression of the appendix.
• Appendix 1.9: Suppression of the appendix.
• Appendix 4.3: Clarification of the existing definition of "essential parameter": reference to "main parameter" removed and details added in order to enhance on-site monitoring of essential parameters.
• Appendix 4.4: Complete updating of subsections II and III of Appendix 4.4 on Eddy Current examination of steam generator tubes to take the new probes (STT) into account and provide a better description of the operating procedures and the acoustic emission examination during the MPS hydraulic proof test.
• Appendix 5.0: Creation of a new appendix (App. 5.0) introducing appendices 5 in order to explicit the consistency of the links between appendices 5.1 to 5.8.
• Appendix 5.3: Alignment of Appendices 5.3 and 5.4 for the calculation of Keq according to the theta combination method. Clarification when |KII| < 0.02 |KI|.
• Appendix 5.4:
  • Incorporation of the Kth2 method from RCC-MRx 2016 (processing thermal
    stresses and interaction with primary stresses linked to the Js method, CEP option)
    to ensure that appendix 5.4 of the RSE-M and Appendix A16 of the RCC-MRx are
    consistent.
  • Additional information to specify the stress-strain curve to be used when calculating parameters kth or Jth (only in the event of a thermal transient) for welded joints (Appendix 5.4, Sub-Section V).
  • Additional information to specify the stress-strain curve to be used when calculating parameter Js (in the absence of a thermal transient) for welded joints (Appendix 5.4, Sub-Section IV).
  • Clarification for the calculation of Keq according to the theta combination method.
  • Clarification when |KII| < 0.02 |KI| (appendix 5.4 § II.5.1 to II.5.3).
  • Correction of sign error on the shear stresses for inlet or outlet sections of an elbow subject to plane bending moment (VII.4.1.2.2.a, VII.4.1.2.2.c and VII.4.1.2.2.e).
  • Clarification of the text concerning the degree of the polynomial used to adjust stresses when calculating stress intensity factors by the influencing coefficients method (II.2.a) and II.2.c)).

• Appendix 8.1: Update of the appendix to be consistent with RCC-M‘s references evolutions.

BINDER III:

• Appendix 3.1.I: Update of the visits tables (Complete, partial and EPR Pre-service inspection (VCI)) with the references to examination methods. The update of the three tables details the references to the new paragraphs of B 4800 « Examination of piping, nozzles and valve components in the MPS and the MSS » and B 4900 « Overall examination of the MPS » modified in 2017.
