Dear Sir:
~hree Mile Island Nuclear Statien, Unit 2 (SE-2)
Cperating license No. DPR-73 Decket :70. 50-320 Inservice Inspecticn P cg a=
Cn July 13, 1978, ve submitted fer ycur reviev and appreval, k0 copies of the Inservice Insuecticn Prcgram for 2 C-2.
Since that ti=e, several er crs have been detected in that submittal. ?erefore, enclosed please find the folleving corrected pages :

Page 9 Attach =ent E: Pages k, 5, 6, 8, 9, 10, 11, 12, 13, Ik, 15 : Pare 5 Attach =ent D: Faies 6 and 8 In additicn, we have noted that your letter of April 21, 1973 granted acceptance of ct.r pre-cc=rercial pu=p and valve testing pregra= for SC-2.
Ecvever, in that letter you indicate ycur belief that the fellowing valves should be recla:isified to AS E Categor/ A and tested accordingly:
OF-Vh A/3 Core Flcoding Discharge CF-75 A/3 REE Discharge to Ccid leg CH-V 107 A/S REE Discharge to Cold Leg AS:E Section :C I'47 2110 defines Category A valves as, " Valves fcr which seat leakage is li=Lted to a specific -av3 u= a= cunt in closed positica for fulfi2-cent of their $2ncticn '. Valves CF-Vk A/3 and CF-75 A/3 are not centa"
-a"-
i sc' aticn t alv es. Instead, these valves Open to supply berated water frc= che Ccre.'1 ceding Tanks to Reactor Vessel whenever the ECS pressure falls below the pressure in the tanks. leakage past these tvc valves (which are ar anged in series) need cct be centrolled in Order for these va' res to f 1 fill their facction.
Each Ccre Flcoding Tank is protected by a pressure relief valve

which exhausts inside containment.
In addition, Surveillance Procedre-:Ic. 23 01-31 requires that the Cere Flooding Ta:i level and pressure be =cnitored each shift, and checked for 4+w. -..r - c, %.,w.,4c _,,

.c-o a
e.-
Supplement 3 of the CC-2 FSAR, Table Ch2.15-1 indicates that leak testing need not be perfc ced for DE-7107 A/3. Following a 1CCA, these valves cpen to provide low pressure injection to the Reacter Vessel at a pressure greater than containment pressure.
~4e, therefore, believe that CF-7h A/3, CF-V5 A/3 and OE-V107 A/3 do not neet the ASSE Section :C definition of Category A valves, and should not be clas-sified er tested as Category A. valves.
'de also believe that these valves were cor eccly classified in our criginal submittal, and that the Tech Syc Surveil-lance Criceria is sufficient to ensure reliable operation of CF-Vh A/B and CF-75 A/3. If you disa.7.,ee with cur categorication of the abcVe-nentioned valves, please infers us at your earliest convenience.
Sincerely, J. G. Herbein Vice President-Generatica JGH:RAL:cjg

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 1s 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 strcke time, whichever is less whenever such a valve is full-stroke tested.
3.
Basis for Recuestine 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 readine'ss 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-VS, AH-V60, AH-V72, AH-V101, AH-V102, AH-V103, and AH-V107 will be confirmed to close in less than 60 seconds as required by the TMI No. 2 Technical Specifications.

tinuously lubricated by fluid being pumped, =casurement of lubricati$n level is not practical nor appropriate in this design.
Note 4 Pu=p bearing te=perature cannet be ceasured 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 measurement of parameter Tb is not practical within the Units of design of this pump.
