English term or phrase: Expansion due to compression (EDC)
Expansion due to compression (EDC) test has been applied to evaluate the performance of nuclear fuel claddings where pellet-cladding mechanical interaction (PCMI) is introduced by swelling of fuel pellets and is triggered by the larger hoop deformation of the pellets, especially during accidental transients.

Описание испытаний:

The Expansion Due to Compression (EDC) test has been developed for the study of irradiated and hydrided cladding failure, under conditions of pellet cladding mechanical interaction, which are expected during a reactivity initiated accident (RIA) or an in-pile test. During the EDC test, a piece of cladding tube is circumferentially loaded in tension due to the expansion of a polymer pellet, axially compressed inside the tube.

Как было определено в программе испытаний, анализ целесообразно провести для условий с сжимающими и растягивающими усилиями, действующими на оболочку. Эксперименты с повышенным давлением теплоносителя (сжатие оболочек свежих твэлов). Это испытания свежих твэлов в ЭТВС МТ-2 (Р=12 МПа), МТ-5 (1^4.9 МПа). МТ-5П (Р=6 МПа) и МТ-6 (Р=2,3 МПа). Повышенное давление приводит к сжатию оболочек и изменению ее формы (продавливание оболочки в область между таблетками топлива, заполнение пространства, сформированного фасками таблеток, и формирование структуры «антибамбук»).
