摘要： The invention relates to a cleaning method for removing deposits containing magnetite out of a pressure vessel of a power plant, during which the deposits are treated with an aqueous cleaning solution, which contains a reducing agent and which is heated to an elevated cleaning temperature, in order to reduce iron III ions to iron II ions. The invention is characterized in that a cleaning solution is introduced into the pressure vessel. This cleaning solution contains an initial substance that releases the reducing agent under the conditions existing during cleaning. Hexamethylenetetramine is preferably used as the initial substance.

摘要： In a fuel element for a pressurized-water reactor, in addition to spacers (6), flow-guiding structural parts (8) are arranged which comprise four outer webs (20) which, in a plane oriented perpendicularly to the central longitudinal axis (4), surround a square inner region (24) of which the centre point (M) lies on the central longitudinal axis (4). At their lower longitudinal side facing the flowing cooling water in the operating state, the outer webs are provided with deflection lugs (30) pointing towards the inner region and are structurally identical, wherein mutually opposite outer webs (20) are arranged mirror-symmetrically with respect to a centre plane (21) extending in the axial direction. Such a structural part (8) forms, at most for a number of fuel rods (2) which is smaller than their total number in the fuel element, cells (12) through which a respective fuel rod (2) is guided, wherein the number of these cells (27), which are situated in a row (14) or column (16), is smaller than the number of the fuel rods (2) respectively situated in this row (14) or column (16).

摘要： The invention relates to a pencil having a pencil shell (1) made of a shell material that can be sharpened and lead (4) retained in a central receiving hole (3) extending in the longitudinal direction of the pencil in the shell material. At least one optical fiber (6) made of a material that can be sharpened and extending in the longitudinal direction of the pin, at least partially enclosed by the material of the pencil shell, is disposed in the pencil shell (1), the light entry surface (7) thereof being disposed at the rear end (14) of the pencil sleeve, such that light can be applied thereto by means of a light source (8) present there, wherein the light output surface (37) of the optical fiber (6) protrudes out the pencil sleeve at the front end (30) thereof.

摘要： The invention relates to a method for the detection of a leakage (30a, b) in a double pipe (2), wherein a medium (22) located in an intermediate chamber (10) between the interior (6) and exterior pipe (8) is moved toward a first end (16a) of the double pipe (2), whereupon medium (22) flows in from the second end (16b). On the first end (16a) the medium (22) is examined for any leakage (30a, b) of a characteristic material (7, 36), upon the detection (34) of which a leakage signal (34) is generated and a location (L1, 2) of the leakage (30a, b) is calculated based on the transport time (Tx) of the characteristic material (7, 36) from the leakage (30a, b) to the first end (16a) and based on the mass flow (Avi, Evi) of the medium (22). A corresponding device (4) contains a conveyor unit (18, 36) for moving the medium (22) through the intermediate chamber (10), a material sensor (28a, b) disposed at the first end (16a) for examining the medium (22) for the characteristic material (7, 36), a mass flow sensor (24a, b) at the first end (16a) for the medium (22), a control and analysis unit (32) for generating a leakage signal (34) and calculating of the location (L1, 2) of the leakage (30a, b) based on the transport time (Tx) and the mass flow sensor (24a, b).

摘要： The invention relates to a fuel element (100) for a boiling water reactor, having a multiplicity of fuel rods (102) which are combined to form a bundle and which stand with the lower end thereof on a lower holding plate (311), and having a fuel element base (101), the upper outlet opening of which faces toward the holding plate (311) and the lower inlet opening of which faces toward a lower core grate (201) of the boiling water reactor, wherein a flow duct (301) extends through the fuel element base (101) between the upper outlet opening and a lower inlet opening along a central longitudinal axis (A), which flow duct (301) is traversed by cooling water during operation, wherein the fuel element base (101) has a throttle element (302) which is spaced apart from the inlet and outlet openings in the direction of the central longitudinal axis (A) and which comprises an impact body (303) which is held centrally in the flow duct (301) by a plurality of webs (401) which extend transversely with respect to the central longitudinal axis (A), which impact body (303) occupies a part of the cross-sectional area of the flow duct (301).
