Action en Previcus Inscection Findines (Closed) Deviations (Report No. SC-02):
Some tack.elding of Gric Cage assemblies was not fully controlled.
C.E. has revised Precedure for Welding Qualification, Revision 3 and tne associated helding Procedure Specifications.
This revision address tne control of cnanges to welding variables and is being implementec.
(Cicsed) Felicwup Item (Report No. 50-02):
Evidence of use of non halo-genated shiccing materials was not on file.
Cemeustion nas found the files and also retested some material in order to preve nonnalcgenatec are usec.

Precurement Controls 1.
Objectives The objectives of tnis area cf the inspection were to verify that:
a.
The fuel fabricator's procurement activities are being imclementec in accordance with the requirements of Criteria IV and VII of 10 CFR 50, Accendix B or approved topical reocrt as excanded and documented in his QA program and QA Manual (s).
b.
The fuel fabricatcr's procurement activities are being isolemented in accordance with tr.e requirements of ANSI N45.2, and ANSI M45.2.13 as aopropriate and as dccumented in his QA program and manual (s) or acoreved tcpical recort.
2.
'Methed of Accomolishment The preceding objectives were accomolished by:
a.
Review of the Ocality Assurance Manual, dated March 1, 1977, Section 3, Precurement Occument Centrol anc Iection 4, Control of Purcnasec Materials, Parts, anc Ccmponents, *nicn estaclisned the general recuirements for precurement contrais.
3 b.
Review of the following procedures Quality Assurance Program Requirements for sucpliers to Comoustion Engineering, Nuclear Products Manufacturing-Windsor, QC-14-09, and Receiving Inspection-Master Sheet, O.S. 330, which establisned specific requi rements.
Inspection of the parts or stock and their purchase orders c.
for seven (7) different items found on hand.
These items included, tubing, poison pellets, castings, springs, bar stock, metal strip and grid straps.
The Inspection Report and Lot History's (receiving) and/or Quality Surveillance Trip Reports were inspected for the particular lots found.
The Quality Control Engineering Release Records, Check Lists, and Shipping Releasts were inspected.
The review of the purchase order, submittal of tecnnical requirements was verified.
d.
Inspection also verified the use of an Acoroved Vendor List (AVL) Nuclear Products Manufacturing-Wincsor nac been used in the placement of the above orders.
Inspection verified annual reaudits or reviews of tnese vencors.

D.
Cmission of Contrni Rod Drive Housinos NDE 1.
Objectives The objectives' of this area of the inspection were to verify that:
a.
A study had been made of a recent problem, omission of non-destructive testing on control rod drive housings, the objectives included verification that the cause of the problem, generic considerations and preventive action Pave teen adcressec.
b.
Independent verification can be found of the accuracy and completeness of the information related to the above.
- Also, verification of the corrective action performed.

c.
Ccoments Cemcustion Engineerings East Windsor plant manufactures Centrol Element Drive Mecnanisms wnica are Class 1 vessels.
The '.cwer Motcr Housing cf sucn is a ferritic stainless steel tyce 403.
The use of :nis material is governed by Ccde Cases 1337 and 1334 Ccce Case 1334 requires material to te annealec or normalized and temce ed.
Ccde Case 1337 requires material to be nondestructively tested if heat treated.
Ccde Case 1334 coes not specifically require nondestructive testing if heat treated, however NB-2520 recuires cuencned and temced ferritic materials to be given nondestructive testing.
Comoustion receives raw material and heat treats this,? if Code Case 1337 and at 1250*F if mate ri al.
Ccmoustion normalizes at 1800*F and tempers at 1125 Code Case 1334. 'In 1974, because of difficulties found in sucoly and also the cesire to have higner fracture tougnaess, Ccmcustion switched frem Code Case 1337 to 1334 When tnis was done, pcst tempering nondestructive testing was crocoec.
Late in 1980, when questioned about this, Ccecustion assumed the drepoing or emis-sien to be an error.
This was recerted to the USNRC as a cossible Part 21 recort.
Later. review and analysis estaolisned that tne cooling.was not quenching but simoly air cccling.
? cst Heat treat nondestructive testing would not be recuired and NB 2520 would not be acplicable in :nis case.
It is also imcortant to note that after tempering a final macnine cut of 0.150" 0.0. and 0.200" I.D. was done therefore any cuench type cracks would nave caen removed by macnining and inceed Cenoustice nas never fcund refectable~ material at tnis point.in facrication.
