DEFINITIONS l.
OBSERVATION - AN ITEM THAT DOES NOT IMPACT THE ADEQUACY OF THE DESIGN OR QA PROCESS BUT HAS SIGNIFICANCE RELATIVE TO CONSERVATISM, DESIGN PRACTICE OR APPLICABLE PROCEDURES.
2.
FINDING - AN ITEM WHICH THE PROJECT REV IE14 INTERNAL COMiMITTEE HAS REVIE1'IED AND HAS DFTERMINED IMPACTS THE ADEQUACY OF THE DESIGN OR QA PROCESS.
3.
CLOSED ITEM - AN. ITEM LIHICH AFTER FURTHER REVIEW CAN BE CLOSED.
4.
OPEN ITEM AND POTENT IAI.
FINDING ARE TES INTERNAL ITEMS AND MiUST BE CATEGORIZED AS OBSERVATION, FINDING OR CLOSED ITEM PRIOR TO REVIEW COiNCLUS ION.
CURRENT STATUS THE FOLL011ING ITEitS HAVE COMPLETEO THE TES REVIEH PROCESS:
FI NOINGS OBSERVATIONS IMPACTEO AREAS
'NTERFACES PROCEDURES PROCESS SPECIFICATIONS STRESS REPORT SUPPORTS E(UIPHENT FINDINGS OBSE RVATIONS 0
INTERIM CONCLUSIONS DESIGN PROCESS AND CONTROL THIS TASK REVIEWED THE ORGANIZATIONAL AND PROCEDURAL PROCESS AND CONTROL ESTABLISHED BY BECllTEL FOR THE SUSQUEHANi'lA PROJECT.
THE PROCESS UTILIZED IS ADEQUATE Al'lD PROVIDES CONTROL OF INTERFACES.
REVIEW AND APPROVAL OF REVISIONS TO DESIGN IS ADEQUATELY CONTROLLED.
DES IGN PROCEDURE THIS TASK REV IEWED THE AVAILABILITY0 PROCEDURES ESTABLISHED BY BECHTEL TO CONTROL THE DEVELOPMENT OF THE DESIGN.
SUFFICIENT AND ADEQUATE PROCEDURES ARE AVAILABLE.
IN THE DEVELOPMENT OF PROCEDURES NORE ATTENTION SHOULD BE VADE TO INTERFACES (WHAT IS THE EFFECT OF PROCEDURE "X" ON PRO-CEDURE "Y" OR ON SPECIFICATIONS).
INTERFACE PROCEDURES THIS TASK TOOK THE RESULTS OF THE REV IEW OF THE DESIGN
- PROCESS, CONTROL AND PROCEDURES AND DETERMINED THE NEED FOR THE EXISTENCE OF INTER-FACE PROCEDURES.
WITH RESPECT TO THE DESIGN PROCESS AND CONTROL SUFFICIENT AND ADEQUATE INTERFACE PROCEDURES ARE AVAILABLE.
WITH RFSPECT TO DESIGN PROCEDURES, THEY APPEAR TO BE DEPARTMENTAL (MECHANICAL, CIVIL, ETC.),
WHICH IS APPROPRIATE, BUT, THESE PROCEDURES SHOULD BE SUBJECTED TO INTER-FACE RE QU IR E MENTS.
IMPLEHENTATION Oi< DESIGN AND INTERFACE PROCEDURES THIS TASK REVIEllED THE ACTUAL IMPLEMENTATION OF THE PREVIOUS TASKS IN DEVELOPING THE DESIGN OF THE FEEDMATER PIPING SYSTEM.
THE INTERFACES BETlfEEN CONSTRUCTION AND DESIGN ARE lfELL ESTABLISHED AND ADHERED TO.
REQUIRED REVIEWS AND APPROVALS ARE CONTROLLED.
SOME PROBLEMS APPEAR TO EXIST IN THE DEPARTMENTAL INTERFACES.
SOME BREAKDO'1'fS HAVE BEEN FOUifD IN THE INTERFACE BETWEEN THE SUPPORT AND CIVIL/
STRUCTURAL GROUP.
(THIS MAY BE A RESULT OF THE ACTUAL DOCUMEi'1TATION OF FINAL DESIGNS. )
IN THE CASE OF IMPLEMENTING THE ANALYSIS REQUIREflENTS OF THE DESIGN SPECIFICATION SOME ASSUMPTIONS HAVE BEEN MADE WHICH ARE NOT SUPPORTED BY THE DOCUMENTATION.
THIS MAY BE A RESULT OF THE USE OF A LARGE NUMBER OF REFERENCES IN THE DESIGN SPECIFICATION THAT ARE CONTROLLED BY INDIVIDUALS OTHER THAt<
THE CERTIFIER OF THE SPECIFICATION.
IT MAY BE A
RESULT OF COMMUNICATION BETWEEN PARTIES THAT DOES NOT END UP BEING RECONCILED IN THE APPROPRIATE DOCUMENTS.
THE DESIGN SPECIFICATION HAS THE MAJOR WEAKNESS NOTED ABOVE lfITH RESPECT TO REFERENCES.
- FURTHER, IT APPEARS THAT THE SPECIFICATION OF AN OPERATING COifDITION CATEGORY IS If'1PROPER.
THIS APPEARS TO RESULT FROi~1 RELIANCE ON AN UNREFERENCED HISTOGRAt1 PREPARED BY GE RATHER THAN ON THE REFERENCED GE SPECIFICATION.
AS-BUILT DOCUMENTATION VS.
PLANT CONFIGURATION THIS TASK TOOK THE'S-BUILT DOCUMFNTATIO,'l SUPPLIED BY BECHTEL AND COf'1PARED IT WITH PLANT CONFIGURATION DATA OBTAINED BY TES.
IN THE PROCESS OF THIS COMPARISON A
NUMBER OF OPEN ITEt S WERE GENERATED.
THIS RESULTED FROtf THE FACT THAT THE AS-BUILT DOCUNEitTATION SUPPLIED TO TES
- WAS, IN FACT, NOT "FIt'lAL."
UPON RECEIPT OF THE "FINAL" DOCUi~1ENTATIorh MANY OF THESE ITEt1S WERE CLOSED OUT.
AT FIRST THIS APPEARED TO BE A PROBLEM, HOWEVER IT PROVIDED TES WITH AN OPPORTUNITY TO TRACK A NUMBER OF ITEMS THROUGH THE BECHTEL PROCESS.
TES ITEtlS WERE NOT TRANS-MITTED TO BECHTEL UNTIL RECEIPT OF THE "FINAL" DOCUMEiNTATION.
THE REVIEWER THEREFORE HAD THE OPPORTUNITY TO DETERMINE IF THE BECHTEL PROCESS HAD RESOLVED THE ITEM.
THIS SITUATIOit ESSENTIALLY PROVIDED TES WITH A DETAILED REVIEW OF TWO REVISIONS IN THE DESIGN PROCESS.
AS NOTED ABOVE, MOST ITEt1S WERE RESOLVED BY THE ESTABLISHED BECHTEL PROCESS AND CONTROLS.
DESIGN DOCUMEilTS VS.
FSAR COMMITMENTS THIS TASK COMPARED THE AS-BUILT DOCUf1ENTATION TO FSAR COMMITMENTS.
WITH THE EXCEPTION OF SOME COMMEflTS NOTED ABOVE AND THE FACT THAT TES IS CONTINUIf'lG REV IEW OF DOCUMENTS RECENT1 Y REQUESTED FROM PPErL THE DESIGN DOCUMENTS REFLECT THE FSAR COMMITMEtlTS.
PP5L AUDIT FINDINGS THIS TASK REVIEWED PPttiL QUALITY ASSURANCE AUDITS, AUDIT FINDINGS AND CORRECTIVE ACTIOit FOLLOW-UP.
ADDITIONALLY A REVIElt OF BECHTEL QUALITY ASSURANCE FUNCTIONS RELATED TO SUSQUEHANNA WAS PERFORMED.
THE QUALITY ASSURANCE ACTIVITIES WERE DETERMINED TO BE ADEQUATE.
THERE l/ERE STILL SOME CORRECTIVE ACTION FOLLOW-UP ITEMS OUTSTANDING ON THE FEEDWATER SYSTEM AT THE COMPLETION OF THE REVIEW BY THE TES AUDITOR.
- HOWEVER, TES HAS DETERMINED THAT PP8iL QUALITY ASSURANCE PERSONNEL HAVE PERFORMED THESE TASKS ADEQUATELY TO DATE AND FURTHER REVIEW BY TES IS NOT REQUIRED.
CONCL US IONS DEFINITIVE CONCLUSIONS CANNOT BE REACHED UNTIL THE REVIEW PROCESS IS COMPLETED.
PRELIMINARY INDICATIONS ARE AS FOLLOWS:
1.
THE QA PROCESS IS ADEQUATE.
2.
THE DESIGN PROCESS REVIEW RESULTED IN FINDINGS.
IN MiOST CASES, TES FEELS THAT THESE WILL NOT IMPACT SAFETY OF THE FEEDl!ATER SYSTEM EVEN THOUGH CURRENT BECHTEL DOCUMENTATION WOULD NOT SUBSTANTIATE THAT COitCLUS ION.
3.
SOME FINDINGS HAVE GENERIC IMPLICATIONS SO THAT EXTENSION OF THE TES REVIEW TO THE TOTAL PLANT CANNOT BE t@DE AT THIS TIME.
