Purpose of the j.espection The inspector informed the licensee that the purpose of the inspection was to:
t a.
Review selected Preoperational Test Procedures; b.
Review the implementation of the licensee's training program for test personnel; and, c.
Review the status of previously identificd unresolved items.
3.
Preoperational Test Procedure Review, Scope The Office of Inspection and Enforcement (IE) Preoperational a.
Inspection Program dealing with Test Procedure Review has the objective of reviewing safety related Category A tests for con-sistency with regulatory requirements, guidance and license commitments.
Jn!ferm criteria are applied in the test procedure review to assure th* technical and administrative adequacy of the procedures. This proorar is. : smpling program which is an ongoing effo-t conducted prior to the performance of said tests and therefore prior to the issur c.c of an operating license.

Review Comments The following comments address inspection review of Preoperational Tests (1) CRDM Procedures Control Rod Drive Mechanism Functional Test, MTX 38.4, TP 330/3, Draft #2, Preliminary Review Meeting 41; Post Core Load CRDM Functional Test, MTX 38.5. TP 330/3A, Draft f2, Preliminary Review Meeting 41; (a) References used for review c f the above test procedures included:
Three Mile Island Unit 2, FSAR, Section 4; CRDM Test Program, BAW 10029, Rev.1, 2 and 3; Instruction Manual for Shim Safety CRDM, #706316-2056, Rev. 3, December 1975; Instruction Manual for Control Rod Drive Control System.
TMI Unit II, December.1975; and, OP 1105-9. TMI Unit I, Control Rod Drive System. Rev. 9 June 13,1975.
(b) As a result of this review the inspector determined that the procedures were consistent with regulatory requirements, and licensee commitments ir. areas of special prerequisite manual drive operation including CRD speed control and position indication guidance.
(1) Latching Capabilities One statement of purgse (item 1.3 of MTX 38.4 and item 1.1 of MTX 38.5) reads "To verify latching capa-bility of each CRDM with a phase current of 11 amperes". The procedure verifies latching by the IN LIMIT and 0% lamps extinguishing as rods are withdrawn.
Rods are latched with 11 amperes LJt then withdrawn at 12 amperes. The maximum permissable latching current
,
is 14 amperes.
The licensee has agreed to revise the purpose statement to reflect what is actually the (_.;
current c., which latching is to be verified
-
during testing. This item is unresolyed pending
~
revision of the above procedures.

4 (ii) The values specified for run, latch and dropout currents in the two procedures do not agree with those listed in the CRDM technical manual paragraph (3.b.(1)(e)).
The licensee produced comments from Babcock and Wilcox which state that the CRDMs for TMI Unit 2 differ from the standard ones in that they have a different motor tube material and the stators are varnished vice epoxy coated. Various values of current limits are specified and these values are The consistent with those listed in the procedures.
inspector had no further questions on this item.
(2) Makeup Purification System The inspector reviewed the Makeup anu Purification System Operational Test Procedure (MTX 99.8, TP 600/4, Draft #2,
,
Preliminary Review Meeting 42) for the proper scope, format and procedure content and found it consistent with regulatcry requirements.
(3) Test Procedure Review Instrument Air Functional Test MTX 90.6 TP 256/3 (
The inspector reviewed TP 256/3, Instrument Air System Fu.iction Test, to assure that the procedure contains sufficient directions so that in performance of the test it will verify:
The abilit.= of the Instrument Air compressors to supply air downstream of the afterfilters at rated conditions.
The proper operation of the air dryer.
The proper operation of the following components on each unit:
Unloading valves.
High discharge temperature trip.
-
High discharge pressure trip.
Low lube oil pressure trip.
NSCCW isolation valve interlock with comoressor start.
Excessive NSCCW flow interlock.
The " Automatic" operation of each unit.
The " Constant Speed" operation of each unit.
The ability of the cooling water regulator to maintain the cooling water temperature.

The following is the inspector's comments on procedure TP 256/3:
(a)
Relief Valves - Testing of The inspector restated the licensee commitment to verify setpoint of all relief valves found without a seal or broken seal. The licensee stated that this is a test policy. The inspector has no further questions on this item, (b)
Documentation of Cleanliness of Air Systen The licensee demonstrated cleanliness of the air system during flush of the system.
After completion of compressor /
dryer tests no formal check of downstream air lines is planned.
The licensee stated that a test of line cleanliness upon completion of system air testing could be performed at random selected points.
This item will be demonstrated to the inspector during a subsequent inspection.

The inspector had no further questions on the procedure with the exception of unresolved items.
(77-01-02)
(4) Preoperation Procedure Status The inspector -tated that a large percentage of the pre-operational procedures that address safety related systems have not been written as of the date of this inspection.
The licensee acknowledged this stated condition and stated that additional effort. which included assignment of additional per-sonnel to the task of procedure writing will be expedited and that a number of procedures would be written within the next sixty days.
4.,
Component Vibration Testing The licensee has requested further information from the A/E in meeting his comitnents to Regulatory Guide 1.68, Appendix A, A.l.C in the area of vibration testing of other components such as piping systens, heat excknger and rotating machinery.
