Ey lett-r deted July 9.1975. we transmitted to ;*ou codel technical srecificatiens relating te hydraulic snubbers and recue:ted thct you subeit an aeplication to amend your Dresden Unit 1 Itchnict! Srecifi-catices to incornerer.e thise rodel technical specifiestions.
You did this by your letter dated October 1,1975, and you indicated that the codel technical specifications were generally acceptable to you.
As a result of co= cents that we received f rom licensees and further consideraticn by ourselves. we have revised the codel technical stecifications te provide some relaxation and clarificatien
~ t~ne requirerents. The revisions consist of:
(1) deletine the reouire ent for periodic disasseeby and inspection of snubl ers. (2) >revisiers for installine additional safety related snubbers vitheut prior ::T.C cevrevt.1:
and, in order to clarify the intent of the specifications. (3) specifyinr that the visual inspection of snubbers should include the fluid reservoir, fluid connections, and sny linkage connections te associated ripint end enchors. (4) identification of all safety related snubbers rather then con-safety related snubbers, and (5) enlarging the scope c f 7able 3.6.1 in the nodel technical specifications to identify safety related snubbers that are (a) in high radiation areas, (b) especially difficult to remove.
(c) inaccessible during normal operation. and (d) accessible durinp ncrral operation.
A cocy of the revised model technical specifications and bases are enclo s e d.
Ir erder t5tt ec -sy crecced vith r erding yeur licente to ir.ccrporate trere technical srecificatian chnnges we request that yce cubr it :n rect d ent te reur Octeber 1.1975. Endlication fer licence e-(nb ar t te reficct the e closed revised rodel technical seccifications acd to icentify the safety reletc4 stubbers and tneir accessibility as recuired by Teile 3.6.1,i the revirrd redel technicel specifications.
The rationale that ycu use fer characterizine a snutber as "especially difficult to remove" er "inacceesible durint nornsi eperatien" should be rtsted in your subeittal.
