摘要： A sensor for monitoring the interior of a sodium-cooled fast breeder reactor comprises a pair of symmetrical magnetic cores (33, 33', 112,112'), a magnetrostrictive or piezoelectric vibrator element (30, 100) bonded to one of the cores, a primary coil (31) and a plurality of secondary coils (32) surrounding the magnetic cores, and a container enclosing the above members. The primary coil (31) applied with an exciting alternating current generates an acoustic signal voltage indicative of sound, if any, originated in the interior of the reactor. The magnetic flux produced by the exciting current is influenced by the temperature and flow velocity of sodium flowing around the sensor, and corresponding voltage signals resulting from the changed magnetic flux are induced in the secondary coils.

摘要： Plant operating conditions 1, apparatus operating conditions 2 and environment conditions 3 are accumulated, combined and put together as a set of plant status variables 8 through a monitor 6, while water chemistry information 4 is accumulated as another set of plant status variables 9. The set of status variables 8 is updated and the past data are accumulated in the set of status variables 9. Periodical inspection data 5 are also accumulated in the set of status variables 9 along with the water chemistry information 4. The set 9 is compressed and stored as a plant chart 11 such as a personal clinical chart. A status variable prediction 12 is performed in consideration of the personality of a plant. Both data of the sets 8 and 10 are compared with each other by comparison means 13. If both the data nearly coincide with each other, the plant is diagnosed to be normal and, if not, it is diagnosed to be abnormal. When the plant is diagnosed to be abnormal, an abnormal apparatus and an abnormal factor are identified.

摘要： Disclosed is a picture display apparatus connected to a low resolution ultrasonic inspector so as to display a picture with high resolution. In the apparatus, an approximate spectrum of a theoretical spectrum representing an object having a known shape as a reference and a spectrum obtained through measurement of the known-shaped object are subject to Fourier transformation so that a transfer function of a measurement device is calculated from the ratio between the respective values obtained through the two operations of Fourier transformation, whereby an unknown shape of an object is displayed on the basis of the transfer function and Fourier transformation values of a measured spectrum of the object having the unknown shape. A modified Gaussian distribution obtained by combining two Gaussian distributions, in which the transformation values of the spatial spectrum of the known shape are reduced in a high frequency range and in which oscillations are less spread, in the high frequency range, is employed as the approximate spectrum of the theoretical spectrum representing the known-shaped object, so that the high frequency components of the spatial spectrum of the unknown shape can be reduced and therefore a clear picture can be displayed with high resoltuion.
