1.0 INTRODUCTION
M~h=ral NorMe Seal Assemblies (MNSA) will be installed at varms matrument nozzia 1 locaraens a Fouchern Cahhnma Edison (SCE), San Onofra Unita 2 and 3. l The MN$A is a muchnical device that acts as a complete replacemen! of the "J" weld betwess the Incomet 600 instmaet nozdas and either the Hot Lag pipe, the Ptidsunser vosesi, or Steam Gensnaar shut. The Amstion of the MNSA is to provost leakage and rustrain the nozzle from j i ejectims a' the event of a through wait crack or weld faihare of a nazde lhe potential ibe theos - events asists due to primary water stress corronon cnicking. The samatural imagrity of several MNSA designs has been demonstrated per Design Raport Addenda (e g., Re8munos l} the addiens each panicular configuration. In addinon, hydrostene and thennosyste tests were perfonned to demonsense the Gratil assis' ability to semi at operadag raad*===, u well as a sepulated design transisms Fissily, a total of three ddEurent MNSA styles were seismiceuy qualdled using very h sesunic input spectra and support

simulating operatus condaions by applyng hydrostanc test pnesure. All three test samples demonstrued adequacy of the seal deogn for thsee very severs conditions (Rafinance 2). For other MNSA designs (Radrence 1) it was opted not to parbnn speci5c seimac tests but to deturndse the seal perfbnnance based on sundarities and on comparisons of the response of the c '
.12j successed testcomingunnons.
While innmasset nomdes are expected to be without any external 4 this is not always the case, as br amample hr the Hot Les Samphes MNSA (Reinrenos 1), which has some i=5=ada' enternsinoeds. The subject eatah is perfonned in order to doestmine the shour force, bandas mommes and ; tormonsi =a==== thr which the Boteost Momged Pressurizar Nousie has been shown acceptside ' in the Astronce 2 seissue tests. These loads serve to qualify other MNSA designs as long as it can be dessoustuned that loads a the nossie seal areas are lower and thes the Gndbil seal design featums are shmilar. 2.0 SIGNIFICANTREgULTS l The MNEAmmanumma Namde Condgunnions tested in Reference 2 were shown to provide " seal tishames" he the huowing loads a tie nosde base: ShourForce: 246.2 [b] BandiesManus 3.600[in b) TonionalMonuma as1Em61 AB8 Combustion Engineering Nuclear Operations
