! Quality Assurance Audits -/
3.
On November 8, 9, and 10,1972, nine design, construction, and staff engineers from offsite conducted an in-depth audit of the Oconee Nuclear Station construction quality control in the mechanical, civil, and electrical areas. The audit was conducted according to a written j procedure which included checklists. It covered organization, pro- .' cedures, documentation, and field verification.
The RO inspector listened to the conference phone call report of the
electrical audit findings to the site const uction and QC management.
! The inspector noted the extent and the detail of the audit and observed , that the audit findings were consistent with the findings of similar l AEC audits.
.. I On December 7,1972, DPC confirmed by telephone that the audit results , ! had been reported in writing and that corrective actions were being l taken and would be documented.
' The inspector also reviewed the report of an operational quality as-surance audit performed by three members of DPC's corporate staff on October 19 and 20, 1972. This was the first operational quality as-surance audit performed at Oconee. The audit was conducted in accord-ance with a predetermined inspection outline. The outline defined the.
items to be audited, the audit prerequisites, the forms to be used
in documenting the audit results, and the audit procedure.

Strong Motion Accelerometers Oconee Unit I will have two self-contained strong motion recorders which start recording on.Olg motion and record continuously for seven l seconds. Calibration and battery checks will be made quarterly. The } inspector observed one unit mounted on a concrete pedestal in the ' tendon gallery. A second recorder will be counted in the reactor ! building and will be identically oriented.
l The inspector observed a small unit, referred to as a seismic trigger, l mounted on the concrete pedestal in the tendon gallery.
It actuates ! a control room alar = annunciator at.05g.
l An instrument test technician informed the thspector that Unit 1 will j have six self-contained peak recording accelerometers, model PRA-103.
One was observed in the tendon gallery. The other five were not inspected.
.- The inspector reviewed the strong motion accelerometer calibration procedures, TP-125/1 and TP-125/2. The inspector also reviewed correspondance from Teledyne - Geotech of Garland, Texas, the manu-facturer of the equipment, regarding calibration instructions for the instruments installed at Oconee station.

Independence of ooerating Quality Assurance Organization A draf t copy of DPC's " Administrative Policy Manual for Operational Quality Assurance of Nuclear Stations" was obtained for review in the regional office. Figure. 4-2 shows that the Staff QA Engineer reports to the Steam Production Department /ssistant Vice President for matters pertaining to operational quality assurance (He has no other duties.) although for administrative purposes he reports to Manager, Operations and Maintenance. The Nuclear Station Suoerintendent reports to the Steam Production Department Assistant Vice President. This independence of the corporate QA organization from the nuclear station operations organization was confirmed by the Steam Production Department Assistant Manager. This item is closed, s 8.
Steam Generator lA Tube Leak On Octobe142,1972, J. W. Hampton informed the inspector by telephone that during a 1000 psig hydrostatic pressure test of the A steam generator for Unit 1, a tube leak was discovered. The leak rate was measured at approximately one cup per minute.
The section of tube containing the leak was removed for examination and analysis. The leak was reported to be in a circumferential crack located approximately 1/3 inch above the top side of the bottom tube sheet.
Previous to this test, the B steam generator for Unit 1 had been - given a successful hydrostatic pressure test (following the repair of three top tube sheet tube weld leaks).

In addition, more than 1000 tubes were given an Eddy currcat inspection one-inch below and two-inches above the top of the bottom tube sheet. The three-inch zone in certain of these tubes was also given an ultrasonic inspection. The results of the tests were not available. They will be reviewed during a subsequent inspection.
. 9.
Administrative Instructions The inspector discussed R0 comments on three administrative instruc-tions which will be incorporated in the 'Hanual for Operational Quality Assurance." The comments and resolutions are as follows: DPC will include an exception for Oconee Units 1 and 2 ;d allow a.
for the existing practice of delegating authority to the Operating Engineer and the Technical Support Engineer to approve certain hydrostatic test procedures and chemistry equipment test proce- , I dures which are governed by a controlling procedure which the Plant Superintendent has approved.
' b.
DPC will revise the definitions of major and minor change.
It was stated that any deficiency ident(fied during a preopera-c.
tional test would be documented and that corrective action would I { be initiated through the " work order" system or through the " resolution of discrepancies."
, d.
DPC will provide words to cover the situation where approvals to test procedure changes are needed during off-shif ts.
Approval ' by phone will be permitted with subsequent documentation of the oral approval.
, ! DPC will include a requirement that test results will be reduced e.
to meaningful and understandable form.
I s i f.
DPC will consider specifying a frequency for review of maintenance; ! periodic, and instrumett procedures.
' . t g.

(d) OP 1103/13, "RC System Leakage," and (e) OP 1103/4, "Soluable - Poison Concentration Control."
Comments on OP 1102/04 and 1103/13 were resolved with the licensee's ' representatives. The cocnents on these two procedures are discussed
below. The inspector had no comment or questions on the remaining titree operating procedures.
. In OP 1102/04, blank spaces were discovered in the part of the pro- ' , cedure in which surveillance requirements are prescribed. The licensee's representatives indicated that at the time this procedure was pre-pared, the inforeation to fill the blanks was not available.
Further, it is the'.r plan to fill in all blanka in this and all other procedures as soon as the information and data becomes availabe.
. In OP 1103/13, there appeared to be a lack of detail tegarding the ' plant status during the leak rate determinacion. For example, the ' procedure does not cover the status of makeup, venting, boration or i deboration and chemical additions to the primary coolant system during tae leak rate determination; yet, each of these parameters , ! could hate an effect on the accuracy of the calculation. The pro-
- cedure does not cover equipment status such as changes in pumps and coolers in service or changing the signal sources for pressure, tem-t perature-, level and flow data. A change in equipment status or sig- ' nal source could introduce errors in the leak rate calculation.

I m 0 DUCTION Initial pt=p testing and hot functional testing at Oconce 1 in late November 1971 and Feb:uary 1972 indicated that the reactor coolant system flow signal was char-acterized by randen fluctuations of approximately one (1) hertz, and of approximately 15% full scale at maxista flow.
Test programs were carried cut to: a) Detemine the cause of the flow signal fluctuations, and b) Determine a correction to the flow signal fluctuations consistent with safety requirements.
2.
SIM RRY OF RESULTS Analysis of the data frem tests at B5W's Alliance Research Center on a mock up of the flow meter instnnent piping system and tests at Oconee in February show that: a.
A relatively broad band of flow turbulence noise exists in the reactor coolant system. The flow tube and the flow instn=ent and piping system respond to and - amplify the system noise in a manner characterized by the gecmetry of the flow tube the length and diameter of the instnmient piping, and the response of the flow , transmitters.
The system noise characteristics were determined by obtaining the power spectral . density (PSD) of several static pressures and differential measurements on Oconce 1.
Figure 1 shows the frequency range and relative signal amplitude envelope for the various measurements, except the flow transmitters, as developed frca the PSD Ana- ' lysis. The frequency range frca approximately 5 h: to 15 h: is that in which the system hydraulic noise occurs. The one hert: flow meter response,(the resonance pe at one h: indicated by the dashed line),then is the characteristic response of the !
flow tube, associated instnnent piping, and the transmitters to the forcing functi
defined by the solid line on figure 1.
l b.
The use of hydraulic snabbing devices in the flow tube instnr.cnt lines was fcund to provide a satisfactory means for conditioning The flow meter signal. A compari- . son of the snubbed flow signal with the unsnubbed flow signal is shown in figure 2.
!
- c.
On the basis of the PSD analysis, it was conc 1uded that the gross system flew is ~ ' stable. The prine factors leading to this conclusion are: a) the absence of any i . ! one resonance frequency ccamon to the individual components of the reactor coolant system. b) Isolating six (6) of seven (7) transmitters on a flow tube cutput sign changes the si;;nal resonance frequency frca approximately one h: to 30 h:, and sig- , nificantly reduces the indicated pulsatien ccaponent of the signal.
! l d.
The hydraulic snubbers in the flow tube instnnent lines cause a time delay in'the j mtput signal. The delay has been analyzed with respect to flow coastdcwn and has
been determined to be acceptable.
, The flux to ficw signal is important for two loss of ficw events: 1) the trip of I ! t ! . .. . - - - -

Figures 3 and 4 shew the estimated flow coastdcta characteristics for mininum syste: + flow under operating conditions for the reacter ecolant punp trips discussed above.
' f (The flow estimates are based en initial HFr data).
Figures 5 and 6 show the respective DNB ratio curves for a trip frem the flux flow signal. The mininum D?.~d ratios are 1.54 and 1.44 respectirely. The ficw recuired to naintain the minimum DNBR of 1.32 is shown by the dashed lines in Figures 3 and 3.
SWmRYONCONCLUSIONS ' The conclusions reached frca the tests and analyses are: , 3.1 Gross system flow is stable.
. i 3.2 The reactor coolant flow measuring system responds to relatively broad band reactc: system noise at the measurement syste-d characteristic frequency.
. 1 3.3 Hydraulic snubbers placed in the flow tube instnnent piping provide an acceptable signal for use in the reactor protection system.
