Bob Dennigexplained the process of the TSB staff wanting to compile the data related to these items and walked the NEI TSTF through the handout. Steve Wideman of WCNOC opened the discussion on establishing priorities and schedules(enclosure 2). Mr. Wideman expressed the Owner's Group (OG) concerns with what they perceive as not enough effort on staff part in completing medium and low priority TSTFs as well as a significant delay in high priority TSTFs. The OG stated that it will be submitting more than forty changes to the STS Rev. 2. Bob Dennig reassured the OG that the NRC is aware of their concerns; however, TSB cannot currently support a large number of TSTF changes and issued a Draft of current pending TSB TSTF actions, (enclosure 3). He informed the OG that TSB needs to know of additional planned STS Conversions in order to be prepared for the future workload. Mr. Wideman discussed the OG preference on approval letters as they related to CLIIP items,specifically, TSTF-358. Mr. Dennig explained that TSB cannot provide an approval letter for TSTF-358 or any other TSTF that is going through the CLIIP process until it has gone through the public comment period. Further discussions on this topic related to the TSTF OG desire to have a chance to discuss TSB/NRC changes to TSTF prior to the TSTF being noticed for public comment, retaining as much as possible the TSTF process of a negotiated, mutually acceptable and correct resolution of the proposed TSTF changes. To the degree the schedule permits and the technical nature of TSB/NRC change warrants, TSB will follow the established TSTF process. The TSTF OG will provide information on other TSTFs they wish CLIIPed; i.e.,

TSTF-287, -283, -204, -364. The TSTF OG will be the keeper of the "Master List" of TSTFs and their priorities. The "Top Ten CLIIP List" is now defunct.David Skeen discussed the deletion of the Monthly Operating Report (MOR). Staff is open toremoving this information from the Technical Specifications with the understanding that staff can receive the information from some other source.Kerri Kavanagh of TSB presented information regarding TSTF-372 and BWROG End StateTopical Report.TSTF-372 proposes a new LCO 3.0.8 for selected support systems delay time. The selectedsystems which are proposed to be added to the new LCO were removed from the standard technical specifications because they did not meet the requirements of 10 CFR 50.36. This has caused an unexpected burden on the licensees. A handout was provided to the TSTF members discussing the history of delay times for the selected support systems (enclosure 4).

Most of the proposed delay times did not match the delay times that were in the old standard technical specifications. Justification for the proposed change was only provided for the snubbers and not the other selected support systems. TSTF-372 has been connected with initiative 7, non technical specification support systemimpact on technical specification LCOs. The staff will review the industry white paper on initiative 7 which is due to the staff the first week of July and evaluate the implementation process for both initiative 7 and the TSTF. The staff will discuss their findings with the RITSTFat the next meeting on July 31, 2001. The staff will also evaluate handling snubbers as a special case since a quick review has been requested by the industry.BWROG End State Topical Report A discussion was held with handouts (enclosure 5) on the BWROG End State Topical Report. The staff observed that the BWROG was supposed to follow the topical report from the CEOG.

This was not the case and will make the review less timely. The BWROG report is not limited to the change of end states from Mode 4 to Mode 3. The BWROG report also proposes changes to 3.0.3 end states and elimination of reducting reactor pressure to less than or equal to 150 psig. The staff also observed that the BWROG report proposes new conditions for some of the LCOs. However, these new conditions were not discussed. Mike Snodderly of DSSA/SPSB discussed the staff's position on possible TSTFs involvingIntegrated Leak Rate Testing Intervals and Hydrogen ControlA discussion was held regarding possible TSTFs on extended type A leak rate test intervalsand Hydrogen Control. A public meeting is scheduled for July 12, 2001 to discuss a possible risk-informed initiative to extend integrated leak rate test intervals. On June 22, 2001, BWROG topical report was received that could result in changes to generic technical specifications involving hydrogen recombiners, and hydrogen and oxygen monitors. Additional discussions were held regarding the importance of the TSTF working group to prioritize future TSTFs relative to existing TSTFs and other impending staff actions such as risk-informed rulemaking to eliminate the need for hydrogen recombiners. Other items discussed included: 1) Revision 2 Issues - Note Alignment, TSB expressedconcerns that there were inconsistencies among the utilities markups for Revision 2, therefore TSB attempted to create uniformity throughout the NUREG Series. The TSTF OG stated that it would provide TSB the most recent version of the Writer's Guide. 2) Process for posting revisions - The new Revision History Style was discussed and the format agreed upon as depicted in the May 29, 2001 letter from NEI. Additionally, it was agreed that approved incorporated TSTF would be email to the TSTF OG for review prior to being posted to the Internet. Lastly, the next TSTF meeting is tentatively scheduled for September 20, 2001.

This limitation ensures that the structural integrity of the containment steel vessel will bemaintained comparable to the original design standards for the life of the facility. Structural integrity is required to ensure that the vessel will withstand the maximum pressure of (40) psig in the event of a (LOCA or steam line break accident).4. Containment electrical penetrations and penetration conductors are protected by eitherdeenergizing circuits not required during reactor operation or by demonstrating the OPERABILITY of primary and backup overcurrent protection circuit breakers during periodic testing.5. The OPERABILITY of the motor operated valves thermal overload protection and/or bypassdevices ensures that these devices will not prevent safety related valves from performing their function.6. The area temperature limitations ensure that safety related equipment will not be subjectedto temperatures in excess of their environmental qualification temperatures.7. This limitation ensures that the structural integrity of the containment steel vessel will bemaintained comparable to the original design standards for the life of the facility. Structural integrity is required to ensure that the vessel will withstand the maximum pressure of (48) psigin the event of a (LOCA or steam line break accident). (15 psig for ice condenser plants).8. This limitation ensures that the structural integrity of the containment steel vessel will bemaintained comparable to the original design standards for the life of the facility.

BWROG End State Topical ReportBWR/4 Proposed ChangesScope: "The assessment considered all Tech Spec end states resulting in a cold shutdown(Mode 4). The analysis then evaluated an alternate end state of remaining in hot shutdown (Mode 3) as a preferred alternative to Mode 4. Other potential preferred alternatives, such as low power operation, were outside the scope of this study."Based on staff review - 3.0.3 end states were considered in this review although it was notspecifically discussed in Introduction/Background. CEOG did not propose changes to 3.0.3 endstates.3.4.3 Safety/Relief Valves Proposed Modification: Delete Required Action B.2 and add Condition C with Required ActionsC.1 and C.2 to address three or more required SRVs inoperable.Comment: No discussion of proposed Condition C.

Proposed Modification: Delete Required Action B.2. Renumber Condition H (and RequiredAction H.1) to Condition I (and Required Action I.1). Renumber Condition G (and Required Actions G.1 and G.2) to Condition H (and Required Actions H.1 and H.2) and remove the"OR" condition. Add a new Condition G that is similar to the existing Condition G but with the first condition ("Two or more ADS valves inoperable") deleted and Required Action G.2 deleted.Comment: Deleting requirement G.2 does not appear to be risk-informed.
