17 June 2003 M. C. Morodo Testa / ST-CV-CE Package # 5: Self-monitoring Replacement of the supervision platform and communications Upgrade of the self-monitoring controls and electricity NF E Décembre 1996 Equipements de chaufferie à caractère industriel – Sécurité dexploitation des générateurs de vapeur deau ou deau surchauffée avec ou sans présence humaine permanente Proposed execution Installation of the supervision: Sept 2003 Estimated duration: 1 week Self-monitoring upgrade: June-July 2004 Estimated duration: 8 weeks

17 June 2003 M. C. Morodo Testa / ST-CV-CE AFNOR NF E Décembre 1996 Ce document a pour objet de définir quatre modes possibles dexploitation des ensembles de production de vapeur deau ou deau surchauffée ainsi que les termes les plus couramment utilisés dans ce domaine, et de fixer les prescriptions générales de sécurité pour chacun de ces modes – mode dexploitation avec présence permanente – mode dexploitation avec présence intermittente – mode dexploitation en télécontrôle – mode dexploitation en autocontrôle Ces définitions et prescriptions concernent la surveillance, la conduite et les équipements de ces ensembles de production

17 June 2003 M. C. Morodo Testa / ST-CV-CE Conclusions Heating plant and compressed air are essential utilities – User and O&M requirements review – Safety requirements review (AFNOR NF E32-020) Work planning must respect operational constraints Hence, the splitting in 2 phases: , which allows the execution of in-house detailed studies while assuring the operational period engagements
