s t Section 1 Establishment of In-Service Inspection Criteria j
s i 1 Millstone Nuclear Power Station Unit 2 Establishment of In-Service Inspection Criteria Revisions to 10CFR50.55a(g) set forth the inspection requirements for nuclear power plant components by referencing the ASME Boiler and Pressure Vessel Code,Section XI, " Rules for In-Service Inspection of Nuclear Power Plant Components." Applicability of Code Addenda depends on the facilities' commercial operation date and the effective amendment to paragraph (b) of 50.55a.
The commercial operation date for Millstone Unit 2 was December 26, 1975.
The first ten-year interval based on the 1974 Edition of ASME Section XI, including the 1975 Summer Addenda, will end on December 26, 1985.
Accordingly, the second ten-year interval will be based on the 1980 Edition of ASME Section XI with Addenda up to and including the Winter 1981 Addenda.
The in-service inspection and testing programs outlined in the attached tabulations have been developed as a result of a design review in accordance with this later Code Edition and Addenda. The extent of examination of Class 1 and 2 pipe welds will remain as is directed by 10CFR50.55a(b)2ii for Class 1 welds and 10CFR50.55a(b)2iv for Class 2 welds.
I b )
, 1 t 1 The methods, procedures, standards for evaluation, repairs, and replace-ments will initially be determined by the requirements of the 198'0 -
Edition of Section XI of the ASME Boiler and Pressure Vessel Code up to and including the winter 1981 Addenda. Northeast Nuclear Energy Company (NNECO) may elect to update these methods, procedures, standards for -
evaluation, repairs, and replacements to the requirements of later editions ,
'~
and addenda of the ASME Section XI Code, as referenced in 10CFR50.
0, It should be noted that Millstone Unit 2 was designed and paEtially I
constructed prior to the adoption of the ASME Code. ,As a result, certain-
~
examinations stipulated by the Code cannot be performed completely, since plant design does not permit direct access to portions of some' examination .
areas. Relief from the inspection requirements of Subsection IWB has- . ,
/
t .
./ ;
been requesthd where those inspection requirements have been determined to be -impractical. Where relief was requested,-specific information has been provided which identifies the applicable Code requirement, justifi-cationtfor the relief request, and the inspection method to be used as an alternate.
Radiation levels in certain areas or of certain components may bb found to prohibit the access for operators or inspectors to perform the inspec-tions or tests described in this program. If source strengths cannot be j reduced and access is still restricted by considerations of compliance
- with the requirements of Regulatory Guides 8.8 and 8.10, relief will be requested from the specific Section XI Code requirements, and alternative examination-or test requirements will be proposed.

1 1, In.the event that repairs or' replacement of pressure-retaining components are required, IWA-4000 (Repair Procedures) and IWA-7000 (Replacements) shall be followed. 10CFR50 permits the use of the latest approved edition and addenda of Section XI, provided that all related requirements are met.

Section 3 In-Service Inspection Program Class 1 Components i h ?
Millstone Unit 2 In-Service Inspection Program Class 1 Components The attached schedule and tabulation of inspections of components and systems of the reactor coolant and associated auxiliary systems of the Hillstone Unit 2 Plant have been compiled to fulfill the second ten-year inspection requirements of the 1980 Edition of Section XI of the ASME Boiler and Pressure Vessel Code up to and including Winter 1981 Addenda. Class 1 piping systems and components were designed and fabricated before the examination requirements of Section XI of the code were formalized. The arrangements and details of the piping systems and components are such that some examinations are limited due to geometric configuration or accessibility. Typically, these limitations exist at fitting-to-fitting welds, such as elbow-to-tee, elbow-to-valve, valve-to-reducer, etc., where geometry or surface conditions preclude ultrasonic coupling or access for the full required scan length. These limitations exist to a lesser degree at pipe-to-fitting welds where examination can sometimes only be fully performed from the pipe side. Welds having such restric-tions will be examined to the extent practical. Where no meaningful examination can be performed, specific relief will be requested as these areas are identified.
In instances where the location of pipe supports or hangers restrict the access available for the examination of pipe welds, the support will be removed unless removal would overstress the piping system. The examination will be performed to the extent practical with the support in place. Where no meaningful examination can be performed, specific relief will be requested as these areas are identified. Reactor coolant pump motor flywheels will be examined in accordance with the provisions of Regulatory Guide 1.14. Inspections of the Millstone Unit 2 reactor pressure vessel will be conducted from the internal surfaces using automated tooling. The inspections will comply with Regulatory Guide 1.150. Ilydraulic and mechanical snubber inspections, including functional testing, will be conducted in accordance with the augmented surveillance requirements of technical specifications and are not included in this program. Some welds in CRD housings (Category B-0) are recessed in the reactor vessel head and are' inaccessible for examination. Accessible welds will be examined as required.

l ASME CLASS 1 COMPONENT NOTES 1.- There are limitations in access to Weld SC-2 as shown on Drawings 25203-29525 caused by the reactor vessel supports. This interference prevents volumetric examination of 19 percent of the ! weld. However, 81 percent of the weld is inspected using the volumetric examination technique.
- 2. Weld SC-1, shown on Drawings 25203-29525, is partially inaccessible because of reactor vessel supports. This interference prevents
! volumetric examination of 39 percent of the weld. However, 61 percent of the weld is inspected using the volumetric examination technique.
- 3. The lower 50 percent of Nozzles NS-2, NS-4, and NS-6 are inaccessible for volumetric examination of Category B-D nozzle-to-shell welds.
These are the three nozzles that contain the integral Reactor Vessel support pads. Although some redesign of this area was accomplished during construction to provide for better inspectability, we must still request a waiver on the Code requirements for 100 percent examination of all nozzles during the inspection interval. As an alternate to volumetric examination, these areas will be monitored l i' ' for leaks and inspected visually for signs of structural distress
- until an inspection method meeting Code requirements can be devised.
j Drawings 25203-29525 and Sketches SK-M97 and SK-M228 show the I-arrangements in the nozzle area. Nozzles NS-1, NS-3, and NS-5 are l accessible and code examinations will be performed. l. I
. I, .
4 .' There are no items of this category at Millstone Unit 2.
- 5. The Reactor Vessel supports at Millstone Unit 2 are integral with three of the six nozzles and are excluded from this. category by Table IWB-2500.
- 6. The steam generator tubing (U-tubes) is examined in accordance with the Millstone Unit No. 2 Plant Technical Specifications.
- 7. A Relief Request was granted from in-service volumetric examinations of-the reactor coolant pump casing welds. By this relief, we are permitted to conduct alternative surface examinations (liquid penetrant) of the' accessible RCP casing wleds, one pump per interval.
Additionally, a visual examination of the accessible internal pressure boundary will be conducted when the pump is disassembled for maintenance.
- 8. As permitted by 10CFR50.55a(b)2(ii), the extent of Class I piping examinations will be determined by the requirements of Table IWB 2600, Category B-J, listed in the 1974 Edition, Summer 1975 Addenda of the ASME Code, Section XI.
- 9. Some of the CRD housing welds are inaccessible.

SECTION 7 In-Service Testing Program for IWP-Pumps
o, o . In-Service Testing Program for IWP-PUMPS This program lists those pumps (26) that are required to perform a specific function in shutting down a reactor or in mitigating the conse-quences of an accident and are provided with an emergency power source. Table IWP specifies the testing frequency and parameters measured or observed for each pump included in this program. When it is not possible or practical to perform a specified in-service test, a testing alterna-tive is referenced as a Relief Request. An in-service test will be performed on each pump at least every three months during operation. Test frequency will be maintained during shutdown periods if practicable. Pumps required to be operable during shutdown will be tested at least every three months during shutdown.

I IWP - Table Notes: Note 1: In lieu of measuring overall vibration amplitude (Mils), the following vibration monitoring program will be implemented. Vibration will be monitored at least quarterly using equipment which collects vibration signatures. Overall vibration amplitudes will be compaired to the following acceptance criteria: Acceptable Range - O to 2.5 Times Reference Velocity. Alert Range - > 2.5 to 5 Times Reference Velocity. Required Action Range - > 5 Times Reference Velocity. Reference velocity shall be the average overall velocity amplitude determined during an in-service test at reference conditions when the pump is known to be operating acceptably. Vibration signatures will be reviewed at least quarterly by a knowledgeable person using appropriate equipment to identify potential bearing degradation or other potential faults. This signature indicates potential bearing degradation or other faults in the unit. Action as required for a pump in the alert range of vibration level will be initiated.
r
- o. . 9 Bearing Temperature Relief Request Components All safety-related pumps.
Test Requirement Measure annually the temperature of centrifugal pump bearings and main shaft bearings of reciprocating pumps at points selected to be responsive
'to changes in temperature of the bearing.
Basis for Relief Bearing metal temperature monitoring can be effective in detecting
= bearing problems. However, the vibration monitoring program established for Millstone Unit 2 is significantly more effective in identifying
~ bearing degradation than an annual measurement of bearing temperature.
Bearing degradation can be detected at a very early stage by vibration signature analysis. All safety related pumps are monitored using equip-ment which is sensitive to low amplitude vibration changes generated by bearing distress. These. low amplitude signals are typically less than 1 percent of the overall vibration amplitude and cannot be detected by a simple amplitude monitoring program conforming to IWP minimum requirements.
c: However, these changes are routinely detected in the established Millstone Unit 2 vibration monitoring program. In addition, many of the safety related pumps are constructed such that bearing metal temperature changes will be quickly dissipated throughout the relatively massive housings, oil reservoirs, and attached casings. As a result, locations at which bearing temperatures could be monitored will respond much less than actual bearing metal temperature, greatly reducing the.sensivitiy of this method of identifying bearing distress. Further, bearing temperature changes are frequently very sudden, rise quickly until the bearing wipes, then return quickly to normal or below normal as the bearing oil flow increases in the wiped bearing. Alternate Testing Record and analyze pump vibration signature at least quarterly. Signature will be measured as a velocity spectrum. Signatures will be analyzed to detect bearing degration. 4
3 , e e Section 8 IN-SERVICE TESTING PROGRAM FOR IW - VALVES
IN-SERVICE TESTING PROGRAM FOR IWV - VALVES The attached program tables include all valves in the Millstone Unit 2 plant which are required to be identified under Subsection IWV of ASME Section XI, 1980 Edition up to and including the Winter 1981 Addenda. The IWV tables listed herein specify the testing frequency and parameters measured or observed for each valve included in the program. When it is not possible or practical to perform a specified in-service test, a testing alternative is referenced as a relief request.
"When relief requests identify valves will be tested at Cold Shutdown,"
the following guidelines will apply: Testing will commence within 48 hours of achieving cold shutdown conditions, proceed in an orderly manner (not to interfere with restoring the plant to operation) until complete. If not completed in a single cold shutdown, testing will continue on subsequent cold shutdowns without repeating a specific valve test until the entire list is completed. Valves which testing indicates are in the Alert Range will be tested during the next cold shutdown. A plant shutdown will not be initiated to meet the requirements of increased testing for these valves.
"When relief requests identify valves will be tested during refueling shutdowns," the following guidelines will apply:
..o .. .
l Testing will be conducted between the time the plant is in the Cold Shutdown condition at the beginning of the refueling shutdown and be completed prior to leaving the Cold Shutdown condition at the end of the refueling outage. Valves which are in the Alert Range will be tested during the next refueling outage. A plant shutdown will not be initiated to meet the requirements of increased testing for these valves. I i i e

RELIEF REQUEST BASIS SYSTEM: ' SAFETY INJECTION
- 1. Valve: 2-SI-008, 009, 010, 011, 012, 113, 123, 133, 143, 401, 405, 410, 414, 427 Category: B Class: 2 1
1 Function: Check valves in HPSI flow paths to prevent backflow. Test Requirement: Exercise valves (full stroke) quarterly. I Basis for Relief: Valves cannot be full stroke exercised during reactor operations since the only full flow path is into the reactor coolant system. HPSI pumps do not have sufficient discharge pressure (1,200 psi) to overcome reactor coolant pressure (2,250 psi). Valves cannot be full stroke exercised during cold shutdown since full HPSI flow into the reactor could result in reactor coolant system overpressurization.
E SYSTEM: -SAFETY INJECTION (CONT.) Alternate Testing: Design flow tests will be conducted during reactor refueling with the reactor head removed. These tests are conducted while filling the reactor pool cavity and effec-tively demonstrate that these check valves do operate properly. Partial stroke exercising will be done quarterly.
- 2. Valve: 2-SI-114, 124, 134, 144, 434, 446 Category: C Class: 2 Function: Check valves in the LPSI flow paths to prevent backflow.
Test Requirement: Exercise valve (full stroke) quarterly Basis for Relief: Valves cannot be full or part stroke exercised during power operation because LPSI pumps cannot overcome SIT pressure downstream of the 2-SI-706 series valves. Pump discharge check valve exercising during operation would require extensive flow path realignment thus rendering the normal LPSI flow path inoperative. L

- 3. Valve: 2-SI-215, 225, 235, 245 Cat.egory: C Class: 1 Function: Prevent backflow into safety injection tank.
Test Requirement: Exercise (full stroke) quarterly. Basis for Relief: Valves cannot be full stroke exercised during reactor operation or cold shutdown since no flow path exists which can accept full flow. Valves cannot be part stroke tested during reactor operation since failure of the test line isolation valve to shut would result in loss of safety injection
. tank level and consequent plant shutdown, further, if this valve fails to reseat, only single valve isolation would exist between the reactor coolant system and the low pressure safety injection tank.
SYSTEM: SAFETY INJECTION (CONT.)
~ Alternate Testing: Valve will be full stroke tested during refueling outages.
- 4. Valve: 2-SI-217, 227, 237, 247 Category: C Class: 1 Function: Prevent backflow from RCS to safety injection header.
Test Requirement: Exercise (full stroke) quarterly. Basis for Relief: Valve cannot be full stroke or part stroke exercised during reactor operation since the large temperature difference between safety injection system water and the reactor coolant system (approximately 400 F) would cause undue thermal stress of the safety. injection nozzles. Alternate Testing: Valve will be full stroke exercised during cold shutdown. J

Section 9 System Pressure Tests i I L
System Pressure Tests Table BCD-5000 presents the system pressure test requirements for the Millstone Unit 2 components and notes departures from Code where it was deemed necessary. s Test requirements for open-ended lines, such as suction lines from
' s.tcrage tanks, and which receive static tests are not addressed in the table, but will be met.
7 The location of check valves in several systems that penetrate the primary containment preclude the Class 1 pressure test boundary from extending outward beyond the first of such valves, usually located inside containment even though the class change boundary is outside containment. In these cases, the Class 1 leakage and pressure test boundary would be the inside check valve. Conversely, pressure tests of Class 2 systems, which are outside containment, would have to be bounded at a stop valve which may or may not be the Class 1/ Class 2 boundary. In systems which contain pumps, it will not be possible to utilize the pump casing as the boundary between high pressure and low pressure tests without overpressurizing suction piping during the high pressure test. In these cases, the discharge isolation valve will be considered the test boundary.

' System: Service Water Category / Class: D-3:r Function: The Service Water System supplies Millstone Unit 2 with Plant Service Water. The system consists of Code Class 3 and Nonnuclear Piping and components designed to three different operating pressures, depending upon service conditions and material selection.'
Test Requirements: -Hydrostatic Testing the three different portions of the system to the pressures listed below and are stipulated in IWD5223(a): Cast Iron Underground PD = 85 psig Relief Valve Inlets PD = 150 psig Balance (majority) of System PD = 100 psig i
\
. b
- Basis for Relief: It is not possible to isolate the various portions of the above system to permit. code pressure test.
NNECO request relief from the requirements of IWD-5223(a) for the two higher pressure (PD = 100 psig and PD = 150 psig) portions of the Service } Water' System' . r Alternative Testing: NNECO proposes to test the entire Service Water System to 94 psig, test pressure (1.1 times PD = 85 psig) based on the cast iron underground portion
; of the system. Although this pressure is lower than the design. pressure for most of the Service i
- Water System, it is approximately 1 times the system operation pressure and would constitute a meaningful hydrostatic test.
