Sotect Alternate Pressurizer Level Indication To R. F. Wilson Loca:on Trailer #11
,[j
/
The Tech Support Procedures Group has developed variation on the method to predict pressurizer level from incicated temperature which should provide better resolution on level than the present procedure being used. The method is dependent on a dead weight tester set on one side of a differential pressure cell.
It should provide le/el change accuracies on the order of + 5 inches and absolute level changes (dependent on RTD reading accuracies) that could yield approximately + 20 inches.
We Fave reviewed the proposed methods and support the effort necessary to verify this method.
It is recommended that the necessary Met-Ed I & C and Paintenance Support be provided to expedite the installation of the required equipment.
J. Costello and F. Tompson of the Procedures group are assigncd to follow through with the mechanical and procedural support frem GPUSC side.
