s Three Mile Island Nuclear Station Unit 1 (TMI-1) Operating License No. DPR-50 Dochet No. 50-289 Technical Seecification Chance Request No. 19. Amendment No. 2 The licensee requests that the enclosed pages be added to Appendix A of the TMI-l Technical Specifications Sectione 3 and h, as appropriate, and that Item 11, Page k-8 (Table h.1-2) be deleted from the existing Technical Specifications. Revised pages 11 and iii of Appendix A Table of Contents are also included. These pages replace those previously submitted by Change Request No. 19 on September 15,1976. Reason for Proposed Change To reflect proposed revisicna to Change Request No.19 Amendment, as a result of the USNRC review of the subject request. Safety Analysis Justifvine Change This proposed Technical Specification Change does not involve any unreviewed safety questions in that it only incorporates additional restrictions to ensure the reliability of hydraulic snubbers already in use at TMI-1. Note that on the grounds that those snubbers which are classified as "especially difficult to remove" are also difficult to properly inspect, the licensee disagrees with the proposed rewording of definition d, Section 3.16 (Bases). Fifty-two of these " difficult" snubbers are located in the Reactor Building and present significant personnel safety hazards to an operator attempting to perform a proper inspection without scaffolding or ladders. Making this equipment available in the Reactor Building during operation is not practical in that containment integrity must be broken to allov ladders of significant length to be brought into the building. The time and additional radiation exposure nece. sary to erect and dismantle temporary scaffolding for each snubber locat;on in this category =akes this approach impractical for frequent inspection. Twenty.three other snubbers are located in the vicinity of main stess lines and present additional personnel safety hazards to the inspector due to the proxit:d t of high te=perature piping during plant power operation. Therefore, the liceuee requests definition d. read as follows:

           "d. Accessible during nor=al operation: Those snubbers that do not meet the criteria of paragraphs b. and c. above."

The licensee disagrees with the proposal to delete the last two paragraphs of Specification h.17.1. If a number of snubbers are found to be inoperable during an inspection due to a cause which can reasonably be construed as a generic problem, the decision to shutdown the reactor solely to inspect inaccessible snubbers vould be mede at the time of reportability. Adherence to an arbitrary periodic inspection interval may be unnecessary from a nuclear safety standpoint and has an unnecessarily harsh effect on plant operation. The licensee requests retaining the verding of Specification 4.16.1 as submitted in A=end=ent 1 to Change Request No. 19 ,

, 3 16 Shock Superessors (Snubbers) Apelicability Applies to the operability of the hydraulic snubbers listed in Table 3.16.1. Objective To identify those conditions for which the operability of the hydraulic anubbers are required and to identify the time limits in which either the snubber must be =ade operable or reactor shutdovn must occur. - Specification 3.16.1 During all modes of operation except Cold Shutdown and Refueling, all safety-related hydraulic snubbers listed in Table 3 16.1 shall be operable except as noted in 3.16.2 through 3.16.4 below. 3.16.2 From and after the time that a hydraulic snubber is determined to be inoperable, continued reactor operation is per=issible only during the succeeding 72 hours unless the snubber is sooner

              =ade operable.

3.16.3 If the require =ents of 3.16.1 and 3.16.2 cannot be =et, an orderly shutdown shall be initiated and the reactor shall be in cold shutdown condition within an additional 36 hours. 3.16.h If a hydraulic snubber is determined to be inoperable while the reactor is in the shutdown or refuel mode, the snubber shall be =ade operable prior to reactor start-ap. 3.16.5 Snubbers =ay be added to safety-related systems without prior License A=endment to Table 3.16.1 provided that a revision to Table 3.16.1 is included with the next License Amendment Request. Bases Snubbers are designed to prevent unrestrained pipe =otion under dynamic loads as night occur during an earthquake or severe transient, while allowing nor=al ther=al =otion during startup and shutdown. The consequence of an inoperable snubber is an increase in the probability of structural dacage to piping as a result of a seismic or other event initiating dynamic loads. It is, therefore, required that all hydraulic snubbers required to protect the primary coolant system or any other safety system or ce=ponent be operable during reactor operation or other pericds when severe transients =ight cause damaging dynamic leads. 1469 256

_ f l . ! Because the snubber protection is required only during relatively low probability events, a period of 72 hours is allowed for repairs or replacements. In case a shutdown is required, the allowance of 36 hours to reach a cold shutdown condition vill permit an orderly shutdown consistent with standard operating procedures. Since plant startup should not co=rence with safety equipment having known defects, specification 3.16.h prohibits startup with inoperable snubbers. Table 3.16.1 lists all hydraulic snubbers installed on nuclear safety related systems throughout the plant. Snubbers were classified for ' the table in accordance with the following guidelines:

a. High Radiation Area During Shutdown: Those snubbers located in a general field of greater than 100 mr/hr, during shutdown.

L. Especially difficult to re=ove: Those snubbers that are elevated more than 10 feet off the floor and that, due to interferences , may not be safely reached from a suitable work platform,

c. Inaccessible during nor=al operation: Those snubbers that are located within an area where the general field is 100 mr/hr. or greater during nor=al operation.

d. Accessible during nor=al operation: Those snubbers that do not meet the criteria of paragraphs b and c above.

4.17 Shock Suueressors (Snubbers) Aeolicability Applies to the inspection of hydraulic snubbers listed in Table 3.171 to deter =ine their operability. Objective To provide assurance of the operability of the hydraulic snubbers. Specification 4.17.1 All hydraulic snubbers whose seal =aterial has been demonstrated by operating experience, lab testing, or analysis to be compatible with the operating environment shall be visually inspected. This inspection shall include but not necessarily be limited to, inspection of hydraulic fluid reservoir, fluid connections, and linkage connections to the piping and anchor to verify snubber operability in eccordance with the following schedule: Number of Snubbers Found Next Required Inoperable During Inspection Inspection or During Inspection Interval Interval 0 18 conths + 25% 1 12 months + 25% 2 6 months I 25% 3, h 12h days T 25% 5, 6. T 62 days _7 25%

              >8, 31 days    + 25%

The required inspection interval shall not be lengthen <ed = ore than one step at a time. Snubbers may be categorized in two groups, " accessible" or

         " inaccessible" based on their accessibility for inspection during reactor operation. Snubbers classified as " accessible" vill be inspected according to the above schedule. Scubbers classified as " inaccessible" vill be inspected according to the above schedule if plant conditions permit or during the first reactor shutdown thereafter.

These two groups may be inspected independently according to the above schedule. h lT.2 All accessible hydraulic snubbers whose seal caterials are other than ethylene propylene or other caterial that has been demonstrated to be conpatible with the operating environment shall be visually inspected for operability at least every 31 days. Snubbers classified as inaccessible whose seal =aterials 1469 273

have not been demonstrated to be co=patible with the operating environ =ent shall be visually inspected fo'r operability at least every 31 days if plant conditions permit or during the first reactor shutdown thereafter. 4.17.3 The initial inspection shall be perfor=ed within 6 =onths from the date of issuance of these specifications. For the purpose of entering the schedule in Specification 4.171, it shall be assuned that the unit had been on a 6 =onth inspection interval. k.17.h Once each refueling cycle, a representative sa ple of 10 snubbers or approximately 10% of the snubbers, whichever is . less, shall be functionelly tested for operability including verification of proper piston =ove=ent, lockup and bleed. For each unit and subsequent unit found inoperable, an additional 10% or ten snubbers, whichever is less, shall be so tested. Snubbers of greater than 50,000 lbs. need not be functionally tested. Bases All safety related hydraulic snubbers are visually inspected for overall integrity and operability. The inspection vill include verification of proper orientation, adequate hydraulic fluid level, and proper attacbnent of snubber to piping and structures. The inspection frequency is based upon =aintaining a constant level of ' snubber protection. Thus the required inspection interval varies inversely with the obsecved snubber failures. The nu=ber of inoperable snubbers found during a required inspection deter =ines the time interval for the next required inspection. Inspections performed before that interval has elapsed may be used as a new reference point to determine the next inspection. However, the results of such early inspections performed before the original required ti=e interval has elapsed (nc=inal ti=e less 25%) =sy not be used to lengthen the required inspection interval. Any inspection whose results require a shorter inspection interval vill override the previous schedule. Experience at operating facilities has shown that the required surveillance progra= should assure an acceptable level of snubber perfor=ance provided thet the seal =aterials are co=patible with the operating environ =ent. Snubbers containing seal material which has not been de=enstrated by operating experience, lab tests, or analysis to be co=patibl, vith the operating environ =ent should be inspected more frequently (every month) until =aterial ec=patibility is confir=ed or an appropriate changeout is co=pleted. Examination of defective snubbers at reactor facilities and caterial tests perfor=ed at several labcratories (Reference 1) has shown that

 =illable gu= polyurethamdeteriorates rapidly under the temperature and =oisture conditions present in many snubber locations. Although
 =olded polyurethane exhibits greater resistance to these conditions, it also =ay be unsuitable for application in the higher te=perature 1469 274

environ =ents. Data are not currently available to precisely define an upper te=perature limit for the =olded polyurethane. Lab tests and in-plant experience indicate that seal materials are available, pri=arily ethylene propylene compounds, which should give satisfactory performance under the most severe conditions expected in reactor installation. To further increase the assurance of snubber reliability, ! functional tests should be performed once each refueling cycle. These tests will include stroking of the snubbers to verify proper pisten movement, lock-up and bleed. Ten percent or ten snubbers, whichever is less, reprer.ents an adequate sample for such tests. Observed failures on these , sa=ples should require testing of additional units. Snubbers designated in Table 3 17 1 as being in high radiation areas j or those especially difficult to re=ove need not be selected for functional tests provided operability was previously verified. Snubbers of rated capacity greater than 50,000 lbs. are exempt i from the functional testing requirements because of the i=- ! practicality of testing such large units. Reference (1) Report H. R.
