. e em Secte and Cbiectives This attachment describes the inservice inspection program fer Class 1 (reacter ecclant syste:) pressure tcundary cc=penents of TEE-2.

The objective of the inservice inspectica prcgram is to previde assurance cf the continuing integrity of the reacter ecolant system while at the same time =inimicing radiation exposure to personnel and plant devntine in the perfer ance of the inspections.

II.

Identificatien cf Class 1 3cundary The Class 1 boundary was established in accordance with 1CCFR50, para-graph 50.2(v) and fcctncte 2 to paragraph 50 55a(g)(1). The Class 1 boundary is shewn in Unit 2 IS: drawings C-3Co-Col-GU2 thru G3CC-005-G'I2 and C-300-C07-GU2.

!!!. Attlicable Ccde Editien and Addenda In accordance with ICC7R50, paragraph 50 55a(b), the applicable Ccde Edition and Addenda are the 197h Edition and Addenda through Sc=ner 1975 IV.

period of Arrlicability In acccrdance with ICCFR50, paragraph 50 55a(g)(h)(i ), this prcgrs= will be applicable frc= May, 1978 to Septenber, 1981. Ecvever, the progrs=

is written in ter=s of the Ccde required ten-year inspection interiel, which vill ec=nence in May, 1978.

V.

Bases fer Insrectier The inspection pregra detailed in Table A-1 belev fellevs the Code, ex-cept that inspecticns are focused en these areas which engineering analysis indicates are subj ect to relatively nere critical ceniitiens of stress, fatigue, radiatien, and/cr ther=al cycles. :nspections are also required of those areas which had recordable indicatiens during the preservice baseline exa 4 ation. It is censidered that inspecticn of areas subj ected to relatively nere critical ccnditiens or which have pre-existing indi-cations vill provide goed assurance cf identification of any pctential problems before significant flaws could develop in the Class 1 cc=penert pressure boundaries.

7'.

Insrection prcera=

Inservice inspec+1:ns vill be carried cut in acccrdance vith Section XI, 197L Editien with Addenda thrcush Sur=er,1975, except that the specific inspecticns to be perfer:ed vill be in accordance with Table A-1 rather than Tables !W3-2500 and TV3-2600 in the Code. It is censidered that this inspecticn progres is an improvement.

JUSTIFICATION NOTES FOR TABLE D-2 Note 1 There are no flow meters installed in the flow path of this pu=p therefore test quantity "Q" connet be measured. An exception is requested per 10CFR50, para-graph 50.55 a (g) (4), since measure =ent of syste= flow would require a design change to this system and therefore not be within the 11=1:s of the current design. Note 2 This is a vertical deep well-type pu=p with the pu=p sub=erged under water at all ti=es. It is not practical to =easure pu=p vibration in this type of installation. Past operating e::perience has shown that =otor vibration is indicative of pu=p =echanical problem in this type of installa; ion. Therefore, motor vibration will be measured in lieu of pu=p vibration. Note 3 This is a vertical deep well-type pu=p with the pu=p sub=erged under water at all ti=es. Pu=p bearings are lubricated by the fluid being pu= ped. There are no installed =eans of =easuring bearing te=perature and the pu=p design, and installation =akes it i= practical to measure in any other =anner. Since the bearings are con-tinuously lubricated by fluid being pu= ped, measure =ent of lubrication level is not practical nor appropriate in this design. Note 4 Pu=p bearing te=perature cannot be =easured on this pump since the bearings are located deep inside the pu=p casing and surrounded by an oil reservoir. An exception is requested per 10CFR50, paragraph 50.55a (g) (4),in that ceasurement of parameter Tb is not practical within the Units of design of this pu=p. / g {C 1 ' ~

NOTES: NOTES APPEAR IN PARENTHESIS IN TYPE OF TEST AND TEST FREQUENCY COLUMNS OF TABLE A-1. (1) These valves are locked valves, Category AE, which will not be exercised, however they will be seat leak tested as required. (2) See Request for Relief, Paragraph A. (3) These valves are tested for operational readiness only during cold shutdowns as their failure could result in loss of contain-ment integrity. See NRC letter to Meted dated November 17, 1976, Enclosure 2, paragraph 2. (4) These valves are containment isolation valves and will be seat leak tested. However, these valves do not function during an accident, and thus do not require functional testing or exercising. (5) See Request for Relief, Paragraph E. (6) See Request for Relief, Paragraph F. (7) See Request for Relief, Paragraph H.

ASME Code Section XI Requirement From Which Relief is Requested Paragraph IWV-3520 (b) which states that check valves that cannot be operated during ncrmal plant operation shall be part-stroked during plant operations and shall be full-stroke exercised during each cold shutdown. 3. Basis for Requesting Relief a. Check valves FW-V18 A and B are normally open during plant operations. to provide feedwater flow to the steam generators. However, there is no practical way to test the valves closed when feedwater flow stops or the plant is in cold shutdown. b. Check valvo.s NR-V269 and NR-V270 are normally open during all modes of plant cperation. Failure to open woulu be obvious due to lack of cooling water flow; however, there is no practical way to test the valves closed. The valves are isolable by manually operated valves in the event of a plant accident condition. (

. Check valve EF-V2 is normally closed during plant c. operation because the emergency feedwater system is not functioning. Due to its location in the system, there is no practical way to full stroke exercise this valve during either plant operation or cold shutdown. d. Check valves EF-V13 A & B are normally closed during plant operation because the emergency feedwater system is not functioning. These valves open when emergency feed is used, but this cannot be done on a regular basis. Therefore, there is no practical way to full stroke these valves during either plant operation or cold shutdown. e. Check valves RB-V4 and RB-V52 are rormally open during plant operation to provide cooling water flow to the Reactor Building Cooling Coils. Failure to open would be obvious due to lack of cooling water flow; however, there is no practical way to test the valves closed. These valves are isolable by manually operated valves in the event of a plant accident condition. 4. Alternative to ASME Code Section XI Requirements As discussed above, there are no safe, practical ways to test the installed check valves closed and no alternate plans to test the valves are considered feasible. B. Corrective Action for Inoperative Valves 1. Valve Identification All the Class 1, 2, and 3 valves identified in Table A-1, TMI No. 2 Valves Requiring Periodic Inservice Inspection 2. ASME Code Section XI Recuirement From Which Relief is Requested Corrective action for inoperable valves require condition be corrected before unit startup from a cold shutdown con-dition in accordance with paragraphs IWV-3410 (g) and IWV-3520(c). 3. Basis for Recuestina Relief Constraints and limits on plant startup with an inoperable valve depend on many specific plant design features and conditions. The limiting conditions for startup and cper-ation have been analyzed and are described in the TMI No. 2 Technical Specifications. \\ \\T' 10 is >

ASME Code Sedtion XI Recuirement From Which Relief is Requested Paragraph IWV-3410 (b) (1) which states that if only limited operation is practical during plant operation the valve shall be part-stroke exercised during plant operation and full-stroked during each cold shutdown. 3. Basis for Requestinc Relief All the valves listed in paragraph C.1 above are in constant operation providing makeup and letdown to the reactor primary system, seal water and cooling water to the reactor coolant pumps, etc. The valves are not designed with a part-stroke capability and any error in the frequent part-stroke testing of the valve could jeopardize the continued safe operation of the reactor coolant system. 4. Alternative to ASME Code Section XI Requirement Each of the valves will be full-stroke tested during plant cold shutdowns exceeding 48 hcurs in duration and more than 92 days have elapsed since the pre /ious valve tests.

o D. Solenoid Valves Stroke Times 1. Valve Identification All Class 1, 2, and 3 solenoid operated valves identified in Table A-1, TMI No. 2 Valves Requiring Periodic Inservice Inspection. 2. ASME Code Section XI Recuirement From Which Relief is Recuested Paragraph IWV-3410 (c) (2) which states that the stroke time for all power-operated valves shall be measured to the nearest second or 10% of the maximum allowable stroke time, whichever is less whenever such a valve is full-stroke tested. 3. Basis for Recuestina Relief Most solenoid operated valves are small, i.e., 1" and smaller in diameter, and their full-stroke time is usually less than one second. Thus, the valve stroke time cannot effectively be measured using normal test equipment such as a stopwatch. 4. Alternative to ASME Code Section XI Requirements All solenoid operated valves will be tested to ensure their operational readiness as required by Section XI; however, the valve full-stroke time will not be recorded for solenoid valves. The only exception to the above testing is that the containment isolation valves AH-V5, AH-V60, AH-V72, AH-V101, AH-V102, AH-V105, and AH-V107 will be confirmed to close in less than 60 seconds as required by the TMI No. 2_ Technical Specifications.

> 2. ASME Code Section XI Recuirement From Which Relief 1s Requested Paragraph IWV-3410 (c) (2) which states that the stroke time for all power-operated valves shall be measured to the nearest second or 10% of the maximum allowable stroke time, whichever is less, whenever such a valve is full-stroke tested. 3. Basis for Requesting Relief These valves are temperature and pressure controlled valves whose operators depend on changes in temperature or flow / pressure to initiate valve operation or change in position. There is no practical way to determine exactly when a nor-mally open control valve starts to close and during normal operation the valve may be only partially open which would not be a full-stroke test. Thus, the time test results for these valves will not be repeatable even though the valve operates as required. 4. Alternative to ASME Code Section XI Requirements Each of the control valves will be functionally tested on a quarterly basis to ensure they operate as required; how-ever, the valve full-stroke time will not be recorded.

ASME Code Se ction XI Requirement From Which Relief 1s Requestec Paragraph IWV-3520 (b) (1) which states that valvec normally open during plant operation whose function is to prevent reversed flow, shall be tested in a manner that proves that the disk travels to the seat promptly on cessation or re-versal of flow. 3 -I G \\A'

. 3. Basis for Requestinc Relief There is no practical way to test these normally open check valves during reactor operation or shutdown. 4. Alternative to ASME Code Section XI Requirements Positive closure of these normally open check valves will be verified once per operating cycle during valve seat leak rate testing. G. Air Ocerated Valve Stroke Times 1. Valve Identification All Class 1, 2 and 3 air operated valves identified in Table A-1, TMI No. 2 Valves Requiring Pericdic Inservice inspection which have a valve stroke time limit of less than three (3) seconds. (These valves will be identified during the initial performance testing of the valves.) 2. ASME Code Section XI Requirement From Which Relief is Requested Paragraph IWV-3410 (c) (2) which states that the stroke time for all power operated valves shall be measured to the nearest second or 10% of the maximum allowable stroke time, whichever is less whenever such a valve is full-stroke tested. Also Paragraph IWV-3410 (c) (3) which states that when an increase of 50% or more for valves with stroke times less than or equal to ten seconds is observed, test frequency snall be increased to once each nonth until corrective action is taken. 3. Basis for Requesting Relief It is considered impractical to reliably measure changes in valve stroke times for valves which stroke open or closed in less than three (3) seconds. For very short stroke times, the variation in measured stroke times can be a large fraction of the established stroke time limit. Thus it is not practical to-meaningfully identify or evaluate the stroke time changes considering human re-action times and the normal timing equipment used. 4. Alternative to ASME Code Section XI Requirements Air operated valves with stroke times limits of three (3) seconds or less will be timed to ensure that they stroke within the established time limit. Variations in stroke time within the three (3) seconds will not be considered cause for increasing the valve test frequency or for de-claring the valve inoperative and instituting valve cor-rective action.

Basis for Recuestinc Relief a. Although MU-V152B and MU-V402B are normally open during normal plant operation, the remainder of the High Pres-sure Injection System cannot be operated during normal operaticn or at each cold shutdown (except in an emer-gency). Thus, there is no practical way to test MU-V152 A-D, MU-V402 A-D and DH-V148 A & 3. b. DH-V1, DH-V2 and DH-V171 are in the decay heat out-line and part-stroking them during normal cperation could overpressurire downstream piping. Full stroke exercising during each cold shutdown would require interuption of decay heat suction which puts the plant in an unsafe condition. Therefore, there is no practical way to test these valves. 4. Alternative to ASME Code Section XI Requirements Each of these valves will be full stroke exercised during each refueling shutdown.
