Claims (1)
- Способ проверки стержня (1) с ядерным топливом, на одном торце которого пробка (3) приварена к оболочке (2), причем витая пружина (5) сжата между пробкой (3) и топливом (4), с использованием детектора (9) электромагнитной индукции, вдоль которого перемещают стержень, путем измерения выходного сигнала детектора, отличающийся тем, что он состоит в записи значения сигнала на базовом участке (S3), получаемого, когда витки пружины расположены на удалении, и других пиковых значений (S4 и S5) сигнала, расположенных рядом с ровным участком кривой, которые получаются при приложении максимальной индуктивной связи, вычислении отношения значении сигнала и в приеме или отбраковке стержня в зависимости от того, является ли это отношение большим или меньшим порогового значения.
