SUBJECT: 10 CFR Part 21 Written Notification



On November 17, 1997, Con Edison submitted, by facsimile, the initial

notification of a condition at Indian Point Unit No. 2 which we

determined to be reportable under the requirements of 10 CFR Part 21.

The reported condition involved a defect in environmentally qualified

Motor Operated Valves which had been installed at the plant.  Subsequent

to that initial notification, we have learned of further test data that

appears to conclude that the MOVs were operable regardless of the defect.

However, since we have not yet fully analyzed this test data and

determined that we are in full agreement with the conclusion based on

that data, we are conservatively submitting this report under Part 21.

The requirements of 10 CFR 21.21 (d)(4) identify specific information to

be included in this written notification.  That information is provided

in the attachment to this letter.



Should you have any questions regarding this matter, please contact Mr.

Charles W.  Jackson, Manager, Nuclear Safety and Licensing.



                                        Very truly yours,

          procedures, a determination that this component may fall in the

          scope of Part 21 was made on September 15, 1997 and a formal

          four located in the Primary Auxiliary Building and three

          located in containment.



(vii)     The corrective action which has been taken.  The improperly

          drilled T-drains were replaced with correctly drilled T-drains.



(viii)    Any advice related to the defect that has been given to
