5928-00-20143 Attachment 1 BRIEF DESCRIPTIONS OF INFORMATION REMOVED FROM THE UFSAR General Changes
- 1. The changes resulting from the sale of TMI-1 from GPUN to AmerGen and designation of AmerGen as the owner/operator/licensee of TMI-1 has resulted in numerous deletions and additions with regard to designations throughout the UFSAR.
Chapter 1 Changes
- 2. Section 1.2.5.h - deleted the description of the hydrogen purge system. This system function deleted because the equipment is not ES equipment.
- 3. Table 1.3-1 was revised resulting in numerous deletions and additions. The EFW Design Bases information was updated and included changes regarding pump capacity, design and licensing basis events, and system service conditions.
- 4. Deleted part of last sentence of paragraph at top of page 1.4-6. This information removed is redundant to information better defined elsewhere in the UFSAR.
- 5. Section 1.4.53 - deleted "Figure 5.3-1 and" from last sentence in this section. Figure 5.3-1 was removed during Update 14.
- 6. Section 1.4.61 - removed "Figure 6.0-4," and replaced with "Drawing 302-831". Drawing 302 831 is the replacement for Figure 6.0-4 and Drawing 302-831 is updated as needed to reflect as built conditions.
Chapter 2 Changes
- 7. Section 2.5 - numerous deletions. Reflects the recent analyses submitted and reviewed by the NRC as documented in License Amendments 210 and 215.
- 8. Section 2.6 - organizational restructuring. Implements TSCR No. 282 - Plant Organization Title.
Chapter 4 Changes
- 9. Table 4.2 numerous deletions. Update of the Loss of Feedwater with Anticipatory Reactor Trip Accident Analysis.
- 10. Sections 4.3.3.h, 4.3.3.j, 4.3.7.b - numerous deletions. To reflect updated Reactor Vessel P/T limits and period of applicability per TSCR No. 270 and as approved by NRC in License Amendment No. 208.
- 11. Section 4.3.10.3 - deleted 2nd paragraph. Paragraph deleted because Section 8.5 addresses this subject.
- 12. Replaced last three paragraphs of section 4.3. Changed to reflect current design basis for Letdown Line Break analysis.
5928-00-20143 Chapter 5 Changes
- 13. Section 5.1.1.2.c - deleted "Containment Purge Ventilation System". This system is not Seismic Class II. UFSAR Section 5.1.1.3.d currently refers to the system correctly as Seismic Class Ill.
- 14. Deleted a paragraph in Section 5.1.2.1.2. Revised the paragraph by adding new information to clarify use of SQUG methodology for seismic verification of equipment.
- 15. Section 5.1.2.2.b - deleted Integrated Control System (ICS) from Seismic II systems list. The system is downgraded to "Anti-Fall-down", Regulatory Required, and QA/QC required.
- 16. Page 5.1 deleted "Water gates in the fuel storage pools". These gates, FH-V-0002 and FH-V-0003 perform no seismic functions other than passive integrity.
- 17. Section 5.2.2.3.3.d.2.a.4 - deleted. Section deleted is a repeat of Section 5.2.2.3.3.d.l.a.2 and as such adds no value. Most of Section 5.2.2.3.3.e was relocated and became a new Section 5.2.2.3.7. This new section was also designated as "Historical."
- 18. Section 5.2.2.5 - revised to clarify design provisions for protection of the containment structure against corrosive influences. Section 5.2.2.5 (a) was deleted because concrete cover provides adequate corrosion protection for the carbon steel reinforcement without the necessity for any coatings and maintenance of any original applied coatings is unnecessary.
The other changes add clarification.
- 19. Section 5.3.1 - deleted "or passive" from second paragraph. The phrase "or passive" was added to section 5.3.1 without any additional basis during Update 1.
- 20. Section 5.3.3.2.a - deleted last part of 3rd paragraph. Referenced the appropriate Tech Spec. section and deleted the incomplete description of when the RB Purge Isolation Valves can be opened.
- 21. Section 5.4 - organizational restructuring. Implements TSCR No. 282 - Plant Organization Title.
- 22. Sections 5.7.5.2.3 and 5.7.5.2.5 were partially deleted. Section 5.7.5.2.3 has been revised to incorporate the pre-stress force acceptance criteria specified in IWL-3221.1. Information regarding tendon grease test sampling methods & acceptance limits was deleted from Section 5.7.5.2.5. This information is not needed in the UFSAR because TMI-1 is required by law to comply with ASME Section XI 1992 Edition through 1992 Addenda, Subsection IWL via 10CFR50.55a.
Chapter 6 Changes
- 23. Removed two sentences in Section 6.0, which discussed design requirement for the hydrogen recombiners. Deleted a paragraph from section 6.1.3.1, which discussed the applicability of NRC Bulletin 88-08 to the TMI-1 design. Deleted a phrase from Table 6.1-5, which identified plant conditions for testing of LPI injection valves (DH-V-4A/B). Deleted a phrase on section 6.1.4, which limited the applicability of a sentence about ECCS system testing to HPI and deleted reference 4. The sentences removed from section 6.0 were partially in conflict with section 6.5.3 and otherwise did not add any new description or requirements not found elsewhere in the UFSAR. The section 6.1.3.1 paragraph was
5928-00-20143 deleted in accordance with letter C311-89-2097 (Hukill to NRC), in which GPUN concluded, "we do not believe that the conditions described in NRC Bulletin 88-08 are applicable to TMI 1". The deletion in Table 6.1-5 is not a necessary requirement per the ASME code and Tech Spec 4.5.2 and therefore the change makes the statement less prescriptive. The phrase removed from section 6.1.4 was inappropriate and had no basis.
- 24. Section 6.4.5 - numerous deletions. Revised section to incorporate new design basis calculation (C-1 101-573-E410-004).
- 25. Deleted information in sections 6.5.3.1, 6.5.3.2, and 6.5.3.3 and replaced with new information. Revised sections to reflect current status of hydrogen generating material inside the RB and to eliminate incorrect information that does not belong in the UFSAR.
- 26. Page 6A deleted footnote. Footnote removed so that there is no confusion about the data in the table.
- 27. Table 6B-6 (Sheet 4 of 6) - deleted the heading "EMERGENCY CORE COOLING SYSTEM" above last paragraph on this page. Heading belongs on Table 6B-6 (Sheet 5 of 6).
- 28. Page 6B-13 deleted TDR-250 footnote. Information moved to C-1101-424-E540-064, Rev. 1.
Chapter 7 Changes
- 29. Section 7.1 - second paragraph, deleted the Oconee Unit 1 information. Information is obsolete and is not part of the TMI-1 RPS.
- 30. Table 7.1 deleted information related to power/ RC pumps trip. Information is redundant.
- 31. Table 7.1 numerous deletions. Update of the Loss of Feedwater with Anticipatory Reactor Trip Accident Analysis.
- 32. Section 7.1.1.7 - deleted reference to IOCFR50.49. Corrected section because not all protection system detectors are required to be environmentally qualified since certain detectors have completed their protective function prior to the Reactor Building becoming a harsh environment.
- 33. Section 7.1.4 was revised resulting in numerous deletions and additions. The EFW Design Bases information was updated and included changes regarding pump capacity, design and licensing basis events, and system service conditions.
- 34. Section 7.2.3.a - modified and Section 7.2.3.4 deleted. To remove excessive detail and redundancies regarding ICS failure considerations.
- 35. Section 7.2.3.1 - deleted last sentence of second paragraph. Removed redundant ICS maneuvering rate information.
- 36. Section 7.2.3.2 - deleted references to Figure 7.2.4 and also deleted Figure 7.2.4. Replaced information with reference to drawing 1 D-621-41-1000, which reflects as built conditions.
- 37. Section 7.2.3.2.c - deleted "The combined actions of the control system and the turbine bypass system permit a load drop of 30 percent without safety valve operation." To remove
5928-00-20143 duplicate capacity information.
- 38. Section 7.2.3.2.d.3 - deleted the last sentence. Removed excessive detail and to correct an inaccuracy in section 7.2.3.2.d.3.
- 39. Section 7.3 - organizational restructuring. Implements TSCR No. 282 - Plant Organization Title.
- 40. Section 7.3.2.2, and Table 7.3 deleted reference to Main Steam Relief Valve Audio Monitoring. Equipment removed from service.
- 41. Table 7.3 deleted diagnostic description evaluation related to cooler discharge pressure and "60 psig". (1) River water cooler flow provides much more useful diagnostic information than cooler discharge pressure; (2) Sections 9.6.1.b and 6.3.2 already address RR-V6 backpressure.
- 42. Section 7.4 - numerous deletions. Updated Control Room Habitability section to account for recent analysis.
Chapter 8 Changes
- 43. Revised Sections 8.2.1.2.f, 8.2.2.2, 8.2.2.4, and 8.2.3.1.a to add clarification regarding single transformer operation. This is follow-up action resulting from CAP T1998-0429, which reported a lack of clarity in station documents relating to operation with one auxiliary transformer out of service.
- 44. Section 8.2.2.7 - deleted the last 3 paragraphs because of excessive/unnecessary detail.
- 45. Deleted Tables 8.2-12 & 8.2-13. Removed tables and incorporated a calculation, by reference, which contains the same data as the tables but which may require periodic update.
Chapter 9 Changes
- 46. Section 9.1.2.1 - Deleted remainder of paragraph beginning with "The addition of a large capacity makeup valve, MU-V217...". Section 9.1.2.6 - deleted "The effect of small break LOCA piping cross-connects is discussed in Section 14.2.2.4." Section 9.5.2.a - deleted the last 2 paragraphs. Section 9.5.2.c - deleted section. Deletion made in Section 9.1.2.1 because there is no discussion in the restart report on MU-V-217. MU-V-217 was added for operational flexibility and is not required for a safety function. Other changes in 9.1.2.1 remove unnecessary detail and eliminate the inappropriate implications. Deleted sentence in Section 9.1.2.6 because it is not true and adds no value. Chapter 14 discusses the effectiveness of HPI to mitigate a LOCA. What is meant by "The effect of small break LOCA piping cross-connects" is not clear. Deleted paragraphs in Section 9.5.2.a and relocated them to Section 6.4. Deleted Section 9.5.2.c and relocated the information to Section 6.1.
- 47. Sections 9.3.2.a, 9.3.2.1, 9.3.2.4, Table 9.3-1 deleted ICCW flow data. Changed text and table to reflect current design and operating information.
- 48. Sections 9.4.3, 9.4.5, 9.4.6, 9.4.7 - various deletions. Removed information that is not part of the licensing basis, redundant, relocated, or inconsistent.
