Introduction Prepared By: Ron Lippy Company: True North Consulting Meeting Dates: June 6, 7, & 8, 2005 Meeting Location: Meeting Notes Main
Committee Comments 1. Major deliverable is to issue OMN-1 Rev.
1and incorporate into OM Code (Appendix III). 2. Discussion of Richardson Letter of
1991—Primarily established path for OM Code: a. OM Code is NOT an
“operability” document b. OM Code is NOT a
“system” code c. OM Code IS an
“operational readiness” determination code d. OM Code IS a
“component” code ISTA/ISTC 1. Code Case for MOVs (OMN-1) and AOVs
(OMN-12) upon being incorporated into OM Code—May revise Valve Categories.
(A, A/C, C and D). 2. Evaluation of “Rapid Acting” Valves and
criteria for determination or acceptance criteria in progress. In particular the determination of
acceptance criteria associated with valves with stroke times <5 seconds. 3. Evaluation of revision to ISTC-1300 for exclusions
to ADS valves to include exercising. 4. Code Case revision to OMN-8 (Control
Valves with Safety Function) for “applicability”. 5. Evaluating definitions in ISTA, in
particular “test interval”. Inquiry
submitted. 6. Clarification of Category A, A/C valves
regarding determination. (gross leakage vs. leakage to satisfy valve safety
function). ISTB 1. Inquiry on replacement of impeller (per
OM-6) requirements regarding re-establishing reference values.—Pump curve is
NOT required by Code for this edition. 2. Inquiry on two instruments being used for
suction and discharge pressure being considered an “instrument loop” and
requiring calculation of square root sum of the squares to determine overall
accuracy.—The instruments are considered individual and are NOT instrument
loops. 3. Changes to ISTB-6200(a), (b) and (c) to
allow analysis for pumps in 4. Consideration of “design flow” definition
regarding CPT. 5. Evaluating using Group A tests for Group
A pumps in lieu of CPT. 6. OMN-6 Code Case (Digital Instruments)
being revised for applicability to later Codes. 7. Code Change being initiated to change
ISTB- from 70% range to 90% range. ISTD 1. FINALLY—ISTD and Section XI interface has
been completed to remove IWF-5000 (and other associated subarticles of
Section Section XI, regarding snubber exams) and reference to OM Code ISTD. 2. OMN-13, (Visual Examination of Snubbers)—Code
Case is undergoing “word smithing” and clarification of extension of snubber
intervals and actions to be taken as a result of failures of maximum number
of snubber visual exams regarding the “re-establishment” of visual exam
intervals.— Ballot Closes 6/13/05. 3. OMN-15, (Extension of Test Intervals for
snubbers). Rev. 1 initiated to
“clarify” formula used in Code Case. NRC has recent concerns and will involve
additional discussions with Subgroup ISTD. 4. Evaluating method of retention of historical
data/papers (also for other subgroups). Next SNUG meeting (Summer Conference) scheduled for
week of July 18, 2005 in NRC 1. Effort to issue DRAFT Final Rule to
endorse 2004 edition of OM Code, Section III and Section XI—No date for
issuance yet. 2. Effort to issue RG 1.84, RG 1.193, 1.147
revision by July/August 2005. RG 1.192 revision will follow. a. Code Case OMN-13
Approved b. Code Case OMN-15
Not Approved 3. 10 CFR 50.69 Issued 4. 10 CFR 50.46c :(ECCS Rule)—Option a. Provides a distinction between break size
and determines “transition break size” for PWRs (14”) and BWRs (20”).
Dependent upon size of break; if less than “transition break size” use Appendix K, if greater, single failure
is eliminated and take credit for non-safety related equipment. MISC. China/Korea
are using certain OM-22
(Check Valves) 1. NIC—Looking at position paper on NIT
qualifications, tracking and trending guide. 2. NRC is looking at previous RRs to
determine if changes to Code needed or additional guidance/changes to ISTC. 3. Working on Code Change to allow “on-line”
disassembly and inspection of check valves.—Should go to MC within 3 months. 4. Clarification on using “historical” info
and past test results for CMP of check valves. 5. OMN-4 is being updated to applicability
of later Codes. Diesel
Group 1. Developing matrix for comparing
parameters requiring monitoring with Tech Spec requirements 2. Evaluating multiple reporting
requirements for “consolidation” of NRC, NEI, INPO, Maint. Rule, etc., a.
Unavailability b.
Reliability AOVs 1. Appendix V? for AOV testing using
performance monitoring techniques is being revised—Should go to MC for review
10/05. Relief
Valves (Appendix I) 1. 2. Inquiry responded to state that 1 RV in
group must be tested at least once every 48 months. ISTE 1. Subsection for ISTE to be issued for
comments soon 2. New Appendices to a. OMN-1
(MOVs)—Appendix III b. OMN-12 (RI
Testing AOVs)—Appendix IV c. AOV Testing
(Performance Monitoring)—Appendix V Pump
Performance Group developing 1. Test Effectiveness Matrix 2. FMEA 3. Lube Oil Analysis 4. Spectral Analysis (Vibrations) Special
Committee Standards Planning 1. RISC Pumps and Valves to have new
Subgroup (10 CFR 50.69. 2. Requirements for Appendix J (Type A)—ON
Hold 3. Condition Monitoring of Rotating
Equipment 4. Reactor Recirc/Coolant Pumps Shaft cracking—Encourage use of OM-24. |
