Answer Explanation:
The 2PR027J is typically a leading indicator of a small SGTL. Per 2BwOA SEC-8, alternate rad monitors for identifying which SG is leaking are:
- - N- The limit of 150 gallons per day per SG is based on the operational LEAKAGE performance criterion in NEI 97
-06, Steam Generator Program Guidelines Program operational LEAKAGE performance criterion in NEI 97
-operational primary to secondary leakage through any one SG shall be limited to 150 gallons with SG tube degradation mechanisms that likelihood of degrading further to a steam generator tube rupture. The operational leakage rate criterion in conjunction with thmeasure for minimizing the frequency of steam generator tube ruptures.
