This letter forwards Licensee Event Report (LER) 95-019-02, documenting an event
;            that occurred at Millstone Nuclear Power Station, Unit No. 2 on May 14,1995. This 3
LER is being submitted pursuant to 10 CFR 50.73(a)(2)(i). This LER supplement J            provides an update on investigation and corrective actions underway for this event.
The following are NNECO's commitments made within this letter. All other statements made within this letter are for information only.                                                                j B16193-01:             An analysis of tne suction piping from the RWST to the high pressure and low piessure safety injection pumps and the containment spray pumps is being performed to quantify water hammer loads generated due to various piping void assumptions. Data obtained from this analysis will be utilized in the pipe stress and support analyses that will fully address the consequences of the postulated events to establish a correlation between the analytical and field inspection findings. These                   ,
analyses will be completed prior to restart of the unit from the current                  ;
outage.
B16193-02:             Actions will be taken to ensure that the RWST piping is returned to full design compliance. Repairs and/or modifications will be completed to
:                                   resolve the discrepancies identified with the piping, supports, and
,                                   anchors. Documentation inconsistencies will be resolved as part of this 4
effort. Analyses will be performed to ensure that the as-buiit configuration of the piping and supports can withstand the design stresses for the system. These actions will be completed prior to restart of the unit from the current outage.

B16193-03:      An investigation is currently in progress to evaluate the results of the previous IEB 79-02 and 79-14 reviews with respect to the support discrepancies identified in this LER. Based on the results of this                 J investigation, other corrective actions will be initiated as appropriate.
