10CFR21 Final Report 21-97-042:
Discrepancies Between General Electric Boiling Wster Reactor Damian Reauirements Documents and System Vendor Manuals
 
==Dear Madam or Sir:==
 
Illinois Power (IP) notified the NkC in 10CFR21 Interim Report 21-97-042 (IP letter U-602855) dated October 7 1997, that an evaluation under 10CFR21 was in -
progress regarding discrepancias between the General Electric (GE) Boiling Water Reactor (BWR) design requirements and system vendor manuals. The evaluation has been completed and IP has concluded that this issue is not reportable under the provisions of10CFR21.
>                                        The interim report stated that on August 21,1997, IP identified a discrepancy between the GE BWR design requiremer ts 22A5604, " Turbine-Generator Control Requirements GE-Nuclear Energy Division," and the field line-up instructions contained in GE vendor manual K2804-0007C, "GEK-64903, Volume III, Steam Turbine-Generator (EHC and TSI Section)." The specific discrepancy identified was a
                              - difference between the GE BWR Design Requirements document and the system                                                        \g
: vendor manual for the specified closing rate of the turbine control valves. Condition Report (CR) 1-97-08-183 was initiated to track an investigation of this issue.                                                        i g
: On August 27,1997, during investigation of CR l-97-08-18'l, IP _ engineers
                            . determined that conflicts may exist between other GE BWR design requirements                                                          i documents and the system vendor manuals. Condition Report (CR) 1-97-08-303 was                                                        l
                            ! initiated to track an investigation of this issue. The design document discrepancy issue L                              was determined to be potentially reportable under the provisions of 10CFR21 on September 2,1997.

* Page 2 The scope of the gemvic issue involved documents supplied by GE under
                      ; specification K2801 which denne the rr pirements for interface between GE supplied
;                        equipment and equipment supplied by others. The Architect-Engineer (AE) for Clinton Power Station was t esponsible for identifying specific requirement specifications and including them in purchase specifications for the equipment suppliers.
                                  . IP has concluded that this issue is not reportable under the provisions of 10CFR21,                    l I
The basis for this conclusion is the review of the AE's program for controlling this process Additionally, the AE's program was previously audited by GE. To provide                                  :
further confidence of program effectiveness, IP reviewed a sample of GE requirements for safety-related or Technical Specification-related equipment and did not _ identify any failures of vendor supplied implementing drawings to meet the GE design requirements.
The AE's program is considered to have been effective in identifying specific requirement specifications and including them in purchase specifications for the equipment suppliers.
Further, the specific discrepancy between the GE BWR Design Requirements document and the system vendor manual for the specified closing rate of the turbine control valves would have no impact on a safety function and therefore would not create a substantial safety hazard ifit had gone uncorrected.
