A debris box is used in conjunction with a device for searching and retrieving a plurality of foreign objects (22, 24, 26) within a steam generator. The debris box (28) may include a container (56) for containing the objects. The container may include a drawer (60) having an opening (62) for inserting the objects therethrough, an enclosing mechanism for enclosing the objects within the container, and a motivating mechanism (76), such as a pneumatic cylinder, for opening and closing the container. The enclosing mechanism may be an elongated housing (70) which at least partially covers the drawer, substantially covers the opening (62) of the drawer (60) in the closed position, and at least partially uncovers the opening of the drawer in the open position. The container (56) may be a closable container which holds the objects and which has a closable opening for enclosing the objects within the closable container. The closable container may include a holder having an opening for inserting the objects therethrough and an elongated barrier which telescopes with the holder. The motivating mechaism telescopes the holder and the elongated barrier between the closed and open positions. The elongated barrier may substantially block the opening of the holder in the closed position and at least partially reveal this opening in the open position.
