I. d, and C. I. f above.
e.
Byron Jackson Drawing No. 2C5299 (33WX-1 STG. Vert. Circ.
Salt Water Cooling Pumps) to verify implementation of items C. I. d and C.1. f above.
f.
The Specification Control Log dated October 20, 1978; Specification fio. S023-405-3A (Salt Water Cooling Pumps 50tiGS, Units 2 & 3); Addendum 1 through 5; and Design Review flotices for Addendums 1, 3, 4, and 5 to verify that the specification was prepared in accordance with Section 11 of the PIPM and covered the items specified in C.1.c, C.1. d, C. I.e, and C.1. f above.
9 Design Calculation fios. M26.7 (Design Temperatures and Pressures of the CCW and SW Cooling Systems), M27.1 (Salt Water Cooling System Pump Sizing), M27.3 (Salt Water Cooling Pumps - Column Length), M27.5 (Stress Range Reduction Factcr of Salt Water), and M26.1 (Component Cooling Water Heat Exchangers) to verify that they were prepared in accordance with Section 14 of the PIPM and covered the items specified in C.1.b and C.I.e above.
h.
Vendor calculations S023-405-3A-38 (Seismic Withstand Capability of Siemans - Allis AC Induction Motor EL-8-5117-90227-4) and 5023-405-3A-7 (Seismic Analysis Salt Water Cooling Pumps) to verify implementation of C.I.d and C.1.f above.
3.
Findings There were no deviations or unresolved items identified in a.
this area of the inspection.
b.
During the examination of calculation M26.7 the inspector noted that the calculations were based en pipe sizes obtained from P&ID 40126-1 (Revision 1) which listed the size of pipe flo. 007 as 28" and pipe flo. 292 as 10".
The present version of this P&ID (Revision 7) listed pipe fio. 007 as 18" and t;o. 292 as 18".
Discussions with LAPD representatives revealed that the responsible engineer, as part of his review of drawine, revisions, considers that impact on design calculations and revises them if necessary.
This appears to be in accordance with Subsection 8.1 of Section 8 of the PIPM which states:
"The Responsible Engineer (RE) approves the drawing after verifying that the design is in accordance with the related checked calculation and/or design criteria";
however, no recalculation was performed in this instance.
D.
Exit Interview An exit interview was held with management representatives on t!ovember 30, 1978.
In addition to those individuals indicated by an asterisk in each Details Section, thcse in attendance were:
J. Bashore, Manager, QA B. L. Lex, Project Manager, Voytle J. V. Morowski, Deputy Division Manager The inspector summarized the scope and deviations identified during the insnection. Management comments were generally for clarification only, o. acknowledgement of the statements by the inspector.

B.
Design Change Control and Design Corrective Action 1.
Objectives The objectives of this area of inspection were to verify that adequate procedures do exist and are being implemented for the control of design changes.
That design changes are reviewed for the impact of the change, proper documentation, transmittal to all affected personnel, adequate justification, plus review and approval equal to that of the original design, also to verify that adequate procedures do exist and are being implemented for identifying deficiencies of a significant or recurring nature, determining the cause of the deficiencies, and initiating corrective action to prevent recurrence.
2.
Method of Accomolishment The preceding objectives were accomplished by:
a.
Review of Project Internal Procedures Manual (PIPM) Section 11, Revision 8, dated August 11,1978, " Specification"; and Project Reference Manual (PRM) Part C. Engineering Section 8, procedure No. CH-C8.30, dated September 25, 1978; to verify that design change control responsibilities have been designated for: the origination, the review and approval, distribution, notification of affected organizations and proper documentation of changes to all engineering specifications.
b.
Review of PIPM Section 8, Revision 12, dated November 6, 1978,
" Drawing Preparation;" and PRM Part C, Section 4, "Bechtel
. Drawings," Revision 2, dated March 8, 1974; " Change Notice" CN-C4-32, dated October 30, 1978, to verify that responsibilities for drawing change control (same as B.2.a) have been established.
c.
Review of PIPM Section 26, Revision 11, dated November 10, 1978, " Field Change Requests", (FCR) to determine how FCR are handled in the main office.
d.
Review of the following documents to verify conformance with the program as described in B.1.a, b, and c.
(1) Drawing Change Notice (DCN) logs for two (2) projects.
(2) Twelve (12) DCNs for one project.
(3) Specification Change Notice (SCrl) log for one project.
(4) Thirteen (13) SCNs and their related specification addendums for one project.
(5) Four FCRs for one project.
(6) Document Review Notice (DRii) log for one project.
(7) Thirteen (13) DRNs relative to the specification addendums noted in B.2.d.(4).
(8) Specification Control Log dated October 20, 1978, and Drawing Control and Schedule Log, dated October 20, 1978.
e.
Review of PIPM Section 45, Revision 0, dated March 20, 1978, to verify that the program provides for the identifying of deficiencies in the design process and initiating of corrective action to prevent recurrence.
f.
Review of the PSAR, Chapter 17.J. Appendix A, Attachment 2.
To determine if the program described in the PIPM Sections 8, 11, 26 and 45 conforms with the approved commitment.
3.
Findinas a.
Within this area of the inspection no unresolved items were identified, however one (1) deviation with the following two (2) examples were identified.
. (1)
During the review of the SCN log, it was determined that a number of specification changes had not been incorporated in the specification within the 120 days limit. The following twelve (12) SCNs were reviewed to verify the issue date and incorporation date:
SCN-No.
Issue Date Incorporation Date C-06 February 15, 1978 September 13, 1978 C-09 April 4, 1978 September 13, 1978 M-16 March 24, 1978 August 22, 1978 M-17 March 24, 1978 August 22, 1978 P-06 May 12, 1978 October 19, 1978 P-07 May 12, 1978 October 6, 1978 P-08 June 5, 1978 Not incorporated as of November 29, 1978 J-03 January 30, 1978 October 2, 1978 J-25 February 27, 1978 October 2, 1978 J-26 March 28, 1978 October 2, 1978 J-28 May 9, 1978 October 2, 1978 CS-50 April 26,1978 October 17, 1978 The inspector reviewed a Bechtel Audit Report, dated July 25, 1977, that identified several SCNs had not been incorporated.
The corrective action for this defich.ncy stated, "The SCNs are now being tracked through the SCN log. When an SCN is overdue for incorporation into a specification an action item memorandum is sent to the applicable discipline advising them they are delinquent." The inspector's review of several of these memorandums indicates the number of delinquencies have been lessened, but it appears that some disciplines are disregarding the notification as well as the program requirement.
(See Enclosure, Item A).
(2)
In addition to the requirements described in Subsection 11.8.2.1, Subsection 11.8.2.2 requires the Engineering Group Supervisor to review SCNs for compliance with design ceiteria, scope change and to confirm the technical adequacy and the Project Engineer to r-view SCNs for final approval. To conform with these requirements and to document that addendum 6 to Specification No. S023-204-3, had been reviewed and approved by the designated reviewers the Document Review Notice, dated September 13, 1978, (that accompanied the addendum) was signed by the Engineering Group Supervisor, Quality Assurance Quality Engineer, Project Engineer and other discipline engineers (some of the above signatures were of designees).
(See Enclosure, Item B).
. (3) Relative to the detection of errors and corrective action to prevent their recurrence, the inspector verified that the Discipline Group Supervisor and Chief Engineer review and approve all engineering drawings, specifications, DCNs, SCNs, and FCRs therefore they stated that they are in a position to evaluate the error and thus implement the corrective action o.f PIPM Section 45 which are; instruction or reassignment of individuals making significant errors in design work or by modifying the procedures controlling design work if the deficiency is other than personnel error.
