Bingham-Willamette Company Docket No. 99900031/79-02 NOTICE OF DEVIATION Based on the results of an NRC inspection conducted on October 29-November 2,1979, it appeared that certain of your activities were not conducted in full compliance with NRC requirements as indicated below:
Criterion V of Appendix B to 10 CFR 50 states, " Activities affecting quality shall be prescribed by documented instructions, procedures, or drawings, or a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings.
Instructions, procedures, or drawings shall include appro-priate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished."
Deviations from these requirements are as follows:
A.
QA Manual Section 9, paragraph 9.2.5.4, states in part, ".
. All welding materials in the Rod Storage Room shall be maintained with respect to size, metallurgy and heat number."
Contrary to the above, certain welding materials in the Rod Storage Room were not maintained with respect to metallurgy and heat number, in that an open canister containing 1/8" Type 8018-C2 clectrodes identified as Heat Number 402T8111, also contained at least two (2) 1/8" Type 7018 electrodes which were subsequently identified as Heat Number 401E6771.
B.
QA Manual Section 9, paragraph 9.2.5.3, states in part, "All welding stick electrode, wire and flux shall be routed through Receiving Inspection where the supplies will be inspected in accordance with the requirements of the purchase order.
QA Manual Section 4, paragraph 4.3.5, states, " Prior to releasing mate-rial to Production, the test reports supplied by the vendor for each item of material will be checked by the Material Recm.ds Technician for compliance with the requirements of the purchase order."
Contrary to the above, E70T-1 weld wire was released to and used by Production, prior to the receipt of test reports from the vendor.
(See DetailsSection I, paragraph B.3.a. (2)).
C.
QA Manual Section 9, paragraph 9.3.2.1, states in part, "All heat treating involving Code items shall be performed in accordance with a written procedure.
." Procedure D50.23, paragraph 3.3, states in part, "During heating and cooling, the temperature difference between any two points on the weld ent as indicated by Thermocouples, shall not exceed 250 F within any 15 foot interval...."
1795 048 800124()
2 Paragraph 3.4 states in part, "During the holding time at the specified stress relieving temperature, the maximum temperature difference be-tween any two points on the weldment, as indicated by Thermocouples, shall not exceed 100 F...."
Contrary to the above, a review of the heat treat charts and records for Class I Motor Stands, a 0. No. 00NO3 and 00N04, revealed that just one (1) thermocouple had been attached to each motor stand which precluded making a determination of temperature difference within any 15 foot interval and within any two points on the weldment.
(See Details Section 1, paragraph C.3.a. (1)).
D.
QA Manual Section 9, paragraph 9.2.6.2, states in part, ".
. The welding foreman shall initiate the Bingham-Willamette ' Welder and Material Record', form WOO 5 card.... The WOO 5 information block is rubber stamped on the back side of a preprinted time card that is contained in the item's work order. The preprinted information on the face of the time card carries as a minimum the Sales Order Number.
The foreman shall enter all required information on the WOO 5 card...."
Paragraph 9.2.9 states in part, "The Plate Shop Tool Room Foreman shall forward.
. all completed WOO 5 cards (Welder and Material Record) to the Quality Assurance Department. Quality Assurance shall assemble the cards into weld records.
The assembled weld records shall become part of customer document package."
Paragraph 9.3.1 states in part, "The following section shall be used to assure that all heat treating performed on Code items.
. shall a
as a minimum meet the requirements of the Code."
i The subsequently referred to welds are required to be postweld heat treated by the Code.
Contrary to the above, a review of postweld heat treat charts and records, and che WOO 5 cards relative to Motor Stands 00NO3 and 00N04 revealed the following discrepancies:
1.
The postweld heat treat (PWHT) charts and records showed that the two (2) Motor Stands were PWHT on August 29, 1979.
2.
The WOO 5 cards showed that the following welding was performed after PWHT, on the indicated joints at the indicated times:
a.
Shielded Metal Arc Welding (SMAW), Joints 34 thru 37 on August 31, 1979.
b.
SMAW, Joint 13-16, on August 30, 1979.
c.
SMAW, Joint 29 to 31, on September 13, 1979.
1795 049
\\
3 d.
Flux Core Arc Welding, Joint 13 and 17, on September 17, 1979.
E.
QA Manual Section 9, paragraph 9.3.2.1, states in part, "All heat treating involving Code items shall be performed in accordance with a written procedure.
Procedure D50.4, paragraph 3.1.1.1 states, "To avoid setting up harmful stress due to temperature gradients within heavy sections, the rates at which temperature of the part is raised and lowered shall be 100 F maximum per hour. This temperature rate limitation shall be restricted to the temperature ranges above 300 F."
Contrary to the above, D50.4, a low temperature stress relief proce-dure (700-750 F) was used to stress relieve eight (8) Seal Sleeves, Drawing No. B-35173 (b), S.O. No. 00N01/4, Serial Nos. 01-1 through 01-8, on February 5,1979 and subsequently approved by Inspection on Febguary 6, 1979, in which the temperature was raised from 450 F to 600 F in 50 minutes, and from 500 F to 600 F in 32 minutes, as shown by the heat treat charts.
F.
Paragraph 9.7.3 of SNT-TC-IA,1975 states in part, "The employer shall in his written practice establish rules covering the duration of inter-rupted service which will require re-examination and re-certification."
Contrary to the above, the employer, BWC did not establish rules covering the duration of interrupted service which would require re-examination and re-certification of NDE personnel in Procedure No. H29.6, Revision 5.
G.
Section 15 of the QA Manual, paragraph 15.2, states in part, "... and further shall identify and segregate the part by placing an Inspection Report Sticker on the part or group of parts with the corresponding Inspection Report Number.
Contrary to the above, a Volute Case, Order No. 15210159, Item No. 101 was not iden*.ified and segregated, in that the Inspection Report Sticker was not attacre.t to the part corresponding to Inspection Report Number 20612.
H.
Section 10 of the QA Manual, paragraph 10.1.1, states in part, "The required inspection operation will be performed by BWC inspection personnel. The accomplishment of these requirements will be verified by Inspection review of the work order to assure all prior operations have been signed off.
Contrary to the above, Inspection did not review Work Order No. IA041, Item No. 109(1) to assure all prior operations had been signed off as illustrated by the following examples:
1.
Authorized Nuclear Inspector witness point had not been signed off on work operation 180-190, check sheet Nc. 13.
1795 050 I
1 4
2.
The heat number of item 4 had not been recorded on work operation 130, check sheet No. 9.
I.
Procedure D50.9., paragraph 2.,, states in part, " Welding Foreman shall document attactment material tad serialize area of attachment on Form 671-3. WOO 5 cards shall be identified ' Temporary Attachment No.,'
which will provide traceabi'ity to welder, weld procedure and filler metal used."
Contrary to the above, the welding foreman did not fill out Form 671-3 on Work Order No.1H041 Item No. 109(1) giving the location of temporary attachments and the WOO 5 was not filled out on Work Order No. 6A235 Item No. 3003A to provide traceability to welder, weld procedure and filler metal used.
J.
Procedure D50.92, paragraph 3.3.1, states in part, "The welding foreman shall... Supply material that has identification to material type.
Contrary to the above the welding foreman did not supply material that was identified to material type for eight (3) lifting lugs welded on Work Order No. (R) 6A235 Item No. 3002.
