Task Order f,'o.
5 1.
Scoce of Work Provide fiRC IE assistance and consultation services in an independent retallurgical analysis of cracking problems experienced in feedwater systems piping at PWR facilities as assigned, and review of licensees analysis and repair programs as outlined in the statement of work below.
===2.
Background===
Cracking in two feedwater lines at D. C. Cook Unit 2 was reported to fiRC IE by the licensee following plant shutdown to investigate leakage inside containment.
Leaking circumfer ntial cracks were identified in the 16-inch elbows joined to the steam generator nozzles.
Subsequent radiographic examinations revealed cracking indications in all feedwater loops of Units 1 and 2 at similar locations.
In response to an flRC IE generic review request, radiographic examination by licensees revealed cracking indications in the steam generator nozzle-to-piping weldments in the San Onofre-1, H. B. Robinson Unit 2, Beaver Valley Unit 1 and Salem Unit 1 facilities at this time.
Further investigation on the extent of the cracking problem is ongoing.
3.
Statement of Wor _k,k Task a.
Provide assistance as required in the review of licensees' original design bases including stress analysis, design modifications and test program results relative to feedwater system repair programs.
Task b.
Provide travel and participation of Parameter, Inc. in f1RC staff meetings with licensees concerning the feedwater piping system cracking problems.
Emphasis of Tasks (a) and (b) will be directed to obtaining an informed bases for an engineering evaluation of the original design analysis, redesign and testing, and assessment as to the acceptability of licensees' modifications to affected piping systems.
Task c.
Review the metallurgical analysis of the cracked weldments by the licensees and their contractor (s) in parallel with fiRC IE metallurgical investigations.
1016 032
Task (c) will be directed to a first-hand review of the licensees and their contractors failure analysis of cracked weld +ents and conclusions reached.
Task (d).
As assigned, conduct independent metallurgical examination of cracked weldments removed from plant specific feedwater piping to determine probable causes of cracking.
Actual laboratory analysis and evaluation under Task (d) shall consist of the following:
(1) Photograph " cracked pipe weldments" as received to preserve physical faatures prior to removing specimens for other tests.
(2) Examine specimen I.D. surfaces and photographically record, at suitable magnification, surface pathology characteristic of corrosion attack and crack initiation sites.
(3) Analysis of weldment I.D. surface deposits for chemical correlation,ith EDAX analysis of deposits in cracks (i.e.,
Item 8).
(4) Examine weldment by x-radiography techniques to determine crack distribution for selective removal of metallurgical specimens.
(5) Conduct optical metallogra"hy eval iaxion of grain structure, substructures and corrosion associoted with typical cracking and corrosion attack.
(6)
Perform chemical analysis of weld and base metals of weldment for acceptance to specifications.
(7)
Evaluate tensile properties and matrix anomalies of weldment utilizing hardness traverse techniques.
(6)
Based on optical metallography studies, conduct SEP examination of microstructures and evaluate the following:
(a) Nature of cracking, crack initiation and progagation mode.
(b)
EDAX analysis of corrosion deposits in fraccJres and correlation with chemical analysis of surface deposits (i.e., item 3).
The NRC will reserve the option to terminate any of the above tasks if, at any point in the activities, meaningful results appear unlikely.
Likewise, the scope may necessitate expansion if any information obtained indicates the need to expand the effort.
5.
Report Reauirements Written reports of the work done under tasks (a) and (b) are to be submitted separately from task (c).
Status reports as work progresses on task (c) are to be verbally communicated to IE Headquarters - Division, A of Reactor Operations Inspection (301-492-8180).
1016 033
Reports under tasks (a) and (b) shall be completed within 30 days following the review of the licensees' programs, as assigned by fiRC IE Headquarters.
The independent metallurgical analysis of samples received from plant specific piping weldrents under task task (d) shall be completed on a collective bases with,n 45 days, with a final report due two weeks following completion of anlaysis.
6.
Special Instructions The flRC shall reimburse Parameter as invoiced for allowable costs occurred in shipment of samples to their designated laboratories for analysis.
Ass unconsumed portions of the weld ents are to be retained with identification for a period of three months, or until advised by f4RC IE Headquarters regarding disposition.

TASK ORDER NO. 6 1.
SCOPE OF UORVs Provide pipe weld testing and evaluation services for Region V, USNRC.
Two welds,re to be examined in situ at the Washington Nuclear Project ~
No. 2 (WNP-2) site, in Benton County, Washington.
2.
OBJECTIVE OF TASK Determine whether the two welds in question have been subjected to radically excessive and non-uniform postweld heat treatment temperatures.
3.
STATEMENT OF WORK Perform hardness tests and metallographic examinations on two welds at WNP-2.
The two welds are located in two reactor feedwater lines inside the containment vessel.
The welds are identified as:
(1) weld no. 7 on WBG lsometric Drawing No. RFU-418-4 (entitled " Reactor Feedwater from Flowmeter to Reactor Vessel (Line A)"); and (2) weld no. 7 on WBG Isometric Drawing Ho. RFW-419-4 (entitled " Reactor Feedwater from Flowmeter to Reactor Vessel (Line B)").
In both cases the welds connect a 24" check valve to a pipe spool.
Two types of tests are to be performed on each weld as described below:
Hardness Tests:
Reference hardness tests and grain size determinations.
Perform hardness tests in accordance with ASTM E-110-61, at six locations around the circumference of the weldment.
At each location, test undisturbed base metal, base metal which has been exposed to heat treatment, the weld heat affected zone and the weld metal.
Metallographic Estimation of Average Grain Size:
Perform in situ metallographic estimation of average grain size at two locations arc.1d the circumference of the weldment.
At each location, perform grain size estimation of the surface of undisturbed base metal, base metal within the zone of heat treatment, and the weld heat affected zone.
Estimation shall be accomplished in accordance with specification ASTM E112-74.
Photomicrographs shall be taken.
Evaluation:
The results of the above testinn and estimation shall be evaluated to determine if the welds have been subjected to radically non-uniform and excessive postweld heat treatment temperatures.
