ABD00075914 COMPLIANCE PLAN CAPITAL ITEMS REACTOR VALVE LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT October 25, 1985 WORK BY Frank G. Jeanson & Process Engineer REVIEWED AND APPROVED BY: Veldon E. Messick Chief Process Engineer ABD00075915 COMPLIANCE PLAN CAPITAL ITEMS REACTOR VALVE LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT TABLE OF CONTENTS I. PURPOSE AND PROCESS DESCRIPTION II. INSTRUMENT SPECIFICATIONS III. DRAWINGS A ABD00075916 COMPLIANCE PLAN CAPITAL ITEMS REACTOR VALVE LIMIT SWITCH REPLACEMENT ABERDEEN CHEMICAL PLANT I. Purpose and Process Description The purpose of this design is to provide the valves on the reactors with accurate indication in the control room of the valve position. The existing limit switches do not provide this accuracy, since they are operated by the position of the actuator and not the actual valve stem. This type of operation does not take into account the possibility of shearing between the valve stem and actuator, which has occurred here in the plant. This poses a potentially hazardous situation for a VCM release. This design will provide each of the designated valves on the reactors with a new limit switch that operates on the position of the valve stem. These new limit switches will provide accurate indication in the control room and eliminate the hazard of a valve being open when it's actuator position is showing closed. A total of 70 valves will be equipped with this new type of limit switch. These limit switches will be mounted on the bracket between the valve and the actuator. Drawings of several different types of valves with the new limit switches are attached. Table I lists the valve location and manufacturer. Table II lists the different types of valves, quantity of each and actuator type. - 4Ur ABD00075917 TABLE I -'*.*1"3s"' 'is-* ------ S** i.- 7=.5. -*7^ gr ^Reactor <-: Valve Location Size 745 v. -+ -t-t' ~r .5K-*` "' 700-A ,. .'iS-w*'*- v^t-7* . . . _ . .* _____ y&ttl. .'S,,.. s- ^gjjnsg-5 Chem Wash Rtrn. 6" Hot HiO Charge 6" Sewer 6" Dump 6" .. jy- -*, Evacuation 8" ,-6" . 4'* - wr" . -^25^=" Manufacturer Jamesbury^B^ll-)- .
