- Calvert Cliffs event review
- 06 operating and maintenance history prior to April 2001
- April 9 06 surveillance problems and NOEO request
- Events subsequent to April 16 grant of NOED
1996
- May - July 1996 - OE Report screened at PINGP
- PINGP lube oils have Total Base Number(TBN) and sulfated ash properties similar to Calvert Cliffs
- No immediate action: fuel sulfur content high (0.18%), no scuffing noted during Preventive Maintenance (PM)
- Corrective actions: Discuss need to change oil with vendors, obtain recommendations for oil change by 1/1/97 to include in PM if required
- Nov 1996 - PINGP engineer attends SACM conference
- Summarized Calvert Cliffs experience as an "incompatibility between an entirely synthetic oil with a high TBN (> 15), high CD classification, and a low sulfur fuel"
- No problems with extensive use of mineral or synthetic lube oil and low sulfur fuel in Sweden, Germany, Switzerland & France
- SACM conclusion was "not enough experience" to "express formal statements about the lubricant-fuel influences"
.~~--~---~
NMC) 3
1996 - 1999
- Late 1996 - Mobil and SACM contacts
- Nov 1998 - 06 5-yr inspection and rebuild (530 hours0.00613 days <br />0.147 hours <br />8.763227e-4 weeks <br />2.01665e-4 months <br />)
- Some carbon buildup, rings move freely, no indications of blow-by
- BG&E experienced engineer involved
- Feb 1999 - PINGP attends SACM Owners Group meeting
- Calvert Cliffs solution included switch to mineral oil
- PINGP engineers report on high temperature in one 06 cylinder
- No linkage of 06 cylinder problem to oil incompatibility
- Nov 1999 - 06 24-hr load test completed successfully NM~

2000 - 2001
- Jan 2000 - Revised OE due date to Nov 2000
- Sulfur content dropping slowly, PINGP perceived that the industry and vendors did not agree with Calvert Cliffs root cause analysis
- May 2000 - 05 5-yr inspection and rebuild (450 hrs)
- No abnormal indications
- PINGP inspections of D5 and D6 found no ring problems, no scuffing, no blow-by, and "exceptional results" after 450 and 530 operating hours
- Calvert Cliffs reported hard deposits under rings, liner scuffing at 140-170 operating hours
Conclusions:
(1) Lube oil change not recommended; (2) Current performance monitoring and PMs adequate to identify condition
- Monthly surveillance runs and inspections satisfactory
- No data suggesting oil incompatibility NMC) 5

"/
First Conference Call With NRC
- Focus on PRA and compensatory measures
- Mr. Carlson substitutes for system engineering
- Site responded to NRC Staff questions
- History of D6 problem requiring NOED
- Apparent cause - high crankcase pressure from blow-by in a single cylinder
- Cause of blow-by not known
- No indication affecting other cylinders/other engines
- Collective engineering judgment: problem limited to E2-B1 Single problematic cylinder exhibiting limited blow-by
- No basis for tie to D5 or Calvert Cliffs
- Additional PRA information requested
- Follow-up callan April 16, 2001, to confirm need for NOED, PRA changes, NMC) 10

Second Conference Call
- NOED needed - engine not re-assembled

- Break-in period
- Load test
- No unusual operating parameters, no blow-by
- All indications were that problem limited to single cylinder NMC) 12
Context of the NOED
- PINGP did not suspect credible common mode failure mechanism before or during the NOED
- Site experience supported preliminary conclusion of an isolated cylinder problem of unknown cause
- Focus was on problematic E2-81
- Available information did not point to oil incompatibility
- Single cylinder
- D5 apparently unaffected
- Did not find any "sticky rings"
- Questionable validity of Calvert Cliffs conclusion
- Different type of oil (mineral v. synthetic)

- Purpose to discuss engine condition
- Agreement on 12-hr run and borescope to confirm "break in" marks
- Many potential root causes discussed
- No root cause matched all PINGP conditions
- Oil incompatibility discussed -- SACM could not explain limitation of symptoms to a single cylinder
- 1300 - PINGP personnel and tech rep discuss status, pursue investigation
- 0047 - Started D6 12-hr load test
- C/C pressure normal
- E2-B1 temperature w/in 50 degrees of others

15
Calvert Cliffs Root Cause Reoort
- First reviewed April 30 - May 2
- Identified technical parallels between events
- Problem initially found in one cylinder
- Established mineral - synthetic distinction not relevant to oil incompatibility issue
- Discussed independent analyses and unanimous conclusion of cause
- Provided root cause team with technical bases for oil incompatibility as the potential cause NMC) 16
Statement of Dennis Carlson
- No vendor recommended oil change
- No information indicated oil incompatibility in April 2001
- Limited role in 06 issue and NOEO
- Provided complete and accurate responses NMC) 17
Statement of Scott Hiedeman
- Before reading the full Calvert Cliffs report had concluded oil incompatibility problem would not develop at PINGP because:
- Vendors did not recommend oil change and assured PINGP engines would not experience oil incompatibility
- PINGP used mineral-based rather than synthetic lube oil
- Absence of operating problems, especially during rebuilds
- Potential problems could be detected in preventive maintenance
- April 2001 incident was limited to a single cylinder NM~
18
StatemeoLof _S~9ttJ~i iedemClIl1cont)
- The full Calvert Cliffs report changed view about the potential for an oil incompatibility problem:
- Realized SACM agreed oil incompatibility was root cause for Calvert Cliffs (contrary to statements made by SACM's U.S. representative)
- Realized symptoms of oil incompatibility could develop in a single cylinder
- Realized significance of "Total Base Number" NMC) 19
SIT Document Timeline
- Document removed from SIT production stack
- Document later retrieved by concerned employee
- Concerned employee determines document appears relevant
- Document returned to NRC production process
- Document produced to SIT
- ECP investigation
- ECP manager informs SIT of investigation results and confirms SIT receipt of document

SIT Document Production
- Promptly investigated individual's action
- Reported incident to SIT/Senior Resident
- Ensured SIT had document
- Determined there was no intent to withhold significant information by individual or PINGP NMC) 21
Statement of Scott Hiedeman -- SIT
~,,---- -----------"-----~
