HYDRAULIC SHOCK ABSORBERS FOR THE YANKEE REACTOR CONTROL RODS
ased on a theoretical constant deceleration range of 6 to 12 Tests were conducted at atmosperic pressure and room temperature. High speed photography and accelerometerBrush recorder techniques were used to obtain and analyze the data. Although the theoretical contour of the ion, the tapor to simplify the maching. A range of hydraulic loss coefficients of 0.9 to 1.5 was used in the design of the test shock absorbers. Test data revealed that the approximation of the theoretical contour by straight line tapers is justified A significant improvement in dashpot performance was obtained for the triple taper design Based on the test data a triple taper hydraulic shock absorber having a hvdraulic loss coefficient of 1.2 and an average deceleration of 10 g's is proposed for the Yankee reactor control rods. It is expected that the maximum deceleration will not cxceed 15 g's. (auth)
