io.2, I "2A" HPI pump. At the time it was found that there was aopw in th( 2A" ,

I i o . . i Lbearing cooler, pumps "2B" and "2C" were available for use. Therefore, the t

o..,i HPI system was not impaired. Also, the use of "2A" was quickly regained wheng ioislI flow was restored. Thus, this incident was of no sienigicance with respect tg I

[s ,a i l Tne cause of the low flow has been determined to be blockage by " crud" buildu,p.

i ii , I When lack of flow was encountered, valve 2/TVC/p was bypassed, and flow was ,

mI restored. A modification vill be implemented to replace portions of the j i,,3i l carbon steel piping with stainless steel.  ;
