PIC SYSTEM APPLICABLE FOR REP (PWR French Fleet) AND EPR
Jan. 31st, 2024 : A multidisciplinary work group validated a new architecture of this system, for all the targeted codes. The implementation of this new architecture proves to be more suited to the civil engineering and equipment applications in all their diversity / complexity of geometry or configuration.
The change in coating system architecture is displayed here in a new template induced by revision 9 of CCTR 91C031. In particular, some application requirements (tolerances surrounding nominal thicknesses, drying times, etc.) must be provided from abacus by the contractor or its representative carrying out the coating works because it depends on the targeted codification. The abacus are provided in the comment sheet following the TDS.
FNP1108 ind E Technical Datasheet also brings an extension of qualification scope to group 105 (up to the maximum temperature in continuous service of 200°C) and the applicability on stainless steel.
Aug. 3rd, 2023 : Technical Datasheet update for dilution range correction of CENTREPOX N EVO product.
Feb. 13th, 2023 : First publication of the system.
The bi-component products "CENTREPOX N NF" et "CENTRIFUGON EAP NF" are renamed "CENTREPOX N EVO" and "CENTRIFUGON EAP EVO" following solvent reformulation of the base (hardeners are not reformulated but commercial trade name also changed to avoid confusion).
The DI/TEGG note ref. D309522042650A and D309522042688A validated the qualification maintaining of all the FNP systems concerned. FNP1108 system succeeds to the FNP1042 system, on the same codifications with the products of the "EVO" segment.
It should be noted that tests were also supported by EDF on the FNP1108 to argue the non-regression of the reformulated system.
Note : FNP1042 system itself succeeded FNP240 in 2017, which had been reformulated to remove ethylbenzene.
