Contract T.o. HRC 05-80-251 TASK OEDER NO. 6 1.
Scope of Work Provide NRC-IE assistance and services in the independent nondestructive examination of the Indian Point Unit 2 reactor vessel lower shell welds, stub tube welds and conduit welds that were exposed to leaking service water.
===2.
Background===
l The Indian' Point Unit 2 plant, owned by' the Consolidated Edison Company of New York, was operating at full power early on October 17 when a nuclear instrument malfunctioned. The plant was shut down about 4:15 a.m., and workers entered the containment to investigate the problem at about 11 a.m.
A large quantity of water was found on the containment building floor and subsequently also in the cavity under the reactor vessel. The containment sumps were filled with water. The total quantity has been estimated to be about 100,000 gallons.
The principal source of leakage was from fan cooler units which are used to cool the air inside containment. Subsequent to the 4:15 a.m. shutdown on October 17, the reactor was restarted twice on that day, and again on the morning of October 20, before the plant was placed in a cold shutdown condition on October 22.
The cavity under the vessel accumulated service water which resulted in wetting the bottom of the vessel to a height of about nine feet.

Statement of Work The required nondestructive examinations and evaluations required are as follows :
Provide a technical evcluation of the suitability of performing magnetic l
a.
particle examination of the Indian Point r it 2 (IP-2) reactor vessel n
lower head without removal of the protective coating, Perform procedure qualification to demonstrate that the magnetic part. cle i
b.
examination methodology to be used is capable'of de.tecting the flaws in the licensee's coated calibration standard, Supplying the necessary qualified (SN-TC-1 A) personnel and equipment, c.
perform and evaluate the results of magnetic particle inspections (ASME Section V),using the AC yoke method, of the following IP-2 reactor vessel welds:
e
. (i)
The circtmferential lower head to snell veld.
(2) The ceridional welds (orange peel) in the lower head.
(3) The circumferential weld (dollar piece) in the lower hcad.
l (4)
One foot of the longitudinal shell welds intersecting the circumferential shell to lower head weld, d.
Supplying the necessary qualified (SN-TC-1 A) personnel and equipment, perform liquid penetrant inspections (ASME Section V) of the following:
(1) 25% of the instrument nozzle to safe-end and safe-end to in-strument socket welds. Those nozzle which are observed to
, have longitudinal marks.should be included in the san'ple.
1 (2) 10% of the conduit welds which could have been exposed to the leaking service water.
Other consultation and support as may be required for the evaluation e.
of the instrument Ocrduit piping or the IP-2 reactor vessel.
4.
Report Requirements The following reports are required:
a.
Verbal progress reports to the IE Headquarte" Project Officer while the inspections are in progress.
b.
A draft report on the results of the inspections and evlauations re-quested within 20 days of completion of the inspections for the Project Officer's review.
Forty (40) copies of a written final report shall be submitted to the c.
IE Project Officer within 30 days of completion of the inspections.
