Inventor: NESTLER ULRICH DIPL ING
IPC: G21C13/087
Filed: 1992-07-04
Abstract: A dynamic pressure chamber (1) for use in a nuclear ractor pressure vessel. Its purpose is to raise the safety imaging and to reduce the likelihood of the pressure vessel rupturing. This is achieved by reducing brittleness caused by the high neutron flux and thermal shocks, esp. near the main seam welds in the pressure vessel near the core. The circular dynamic pressure chamber (1) is mounted in a strain free manner, from either the upper (2) or lower (3) shell of the reactor pressure vessel. The dynamic pressure vessel (1) is filled with gas e.g. nitrogen or an inert gas or a neutron absorbing fluid e.g. a soln. contg. 2200 to 7000 ppm of boron. USE/ADVANTAGE - The dynamic pressure chamber increases safety margins, and guards against thermal shocks caused by a pressure step of ratio greater than 1:2. Reactor core containment is therefore guaranteed. The dynamic pressure chamber also provides extra biological protection and ensures the reactor presure vessel operates within its defined safety limits over the reactors lifetime.

Title: Electrical circuit for ultrasonic cleaning device - incorporates pulse width modulation for regulating power output resonance frequency
Inventor: KUECK ALFRED
IPC: B06B1/02
Filed: 1992-10-01
Abstract: The electrical circuit has an ultrasonic generator and an ultrasonic transducer, the ultrasonic generator having a power end stage (6) supplying a HF transformer (5) and the ultrasonic transducer using a piezoelectric element (8) which is caused to oscillate at an ultrasonic frequency, upon application of the HF voltage.
