Description

Stimulated by the load following operation of French nuclear power plants. Framatome undertook thorough examinations of the control assemblies' behaviour. Equipment of various kind was developed for this purpose: On-site measuring devices, a stepping motion simulation bench, and a hydraulic test loop. The examinations have yielded knowledge on wear kinetics and made it possible to determine the currently enforced control assembly management criteria. They have also enabled corrective actions, viz., control rod surface hardening and the development of new guide tubes. (orig.)

Abstract (German)

Der Lastfolgebetrieb der franzoesischen Reaktoren hat gruendliche Untersuchungen des Steuerelementverhaltens veranlasst. Verschiedene Pruefeinrichtungen, wie Messgeraete zum Gebrauch vor Ort, eine Messbank zur Simulation von Schrittbewegungen und ein hydraulischer Versuchskreislauf, wurden zu diesem Zweck entwickelt. Aus den Versuchen ergaben sich neue Erkenntnisse zum Verschleissverhalten und eine verschaerfte Einsatzstrategie fuer Steuerelemente. Weiterhin fuehrte die Versuche zur Oberflaechenhaertung bei den Elementen und zur Entwicklung verbesserter Fuehrungsrohre. (orig.)
