Reactor Pressure Vessel and Associated Pi in H drostatic Test ao Introduction:
The object of the hydrostatic test.is to verify the integrity, strength, and leak tightness of:
the reactor pressure vessel; connecting piping welds; and the main steam lines.
The test is performed at 125 percent of the design pressure rating of the reactor pressure vessel.
The hydrostatic test boundaries consist of the following as defined by the initial valve lineup and by the piping and instru-ment diagrams:
(1)
Reactor pressure vessel and recirculation system; (2)
Main steam lines to the turbine stop valves and bypass valves; and, (3)
Portions of the following systems; Residual Heat Removal; Reactor Core Isolation Cooling; Reactor Water Clean Up; High Pressure Coolant Injection; and, Standby Liquid Contro b.

The hydrostatic test consisted of filling the reactor pressure vessel and all associated piping to the first boundary valve, including the main steam piping to the turbine stop valves and the bypass valves.
Initial heat up of the coolant was effected by running the reactor recirculation pumps.
Subsequent heat up was by supplying pre-heated water to the hydrostatic test pumps, with temperature being maintained by recirculating with the condensate pumps.
With the reactor coolant temperature above minimum for boltup and tensioning of the reactor pressure vessel head, and above minimum for pressurization, the hydrostatic test was begun with pressure
plateaus of 100, 650, 1250, PSIG and a final hydrostatic test pressure at 1610 PSIG for a minimum of 10 minu$es.
The average temperature at these pressure plateaus was 151 F.
After completion of the 1610 PSIG hold for a minimum of 10 minutes, pressure was reduced to 1360 PSIG and held there until leak inspection of all welds and mechanical fittings within the test boundary was performed.
Observations:
Prior to,the start of the test, the inspector verified the following:
Valve positions were checked; I
Latest drawing revisions were used in conjunction with the valve lineup lists; Latest boundary diagrams were in use; Calibrated, serialized, and dated pressure gauges of proper range had been installed with gauge number 1 having been designated as the "Official Gauge" and similar gauges numbered 2 and '3 had been installed as backup gauges; Overpressure protection was provided by an installed, pressure-range and capacity stamped, serialized relief valve with a second installed relief valve as a backup; Reactor pressure vessel an'd main steam line coolant was above the specified minimum temperature; Required supporting systems were functional; All welded joints and mechanical connections were uncovered; All temporary instrumentation had been installed and calibrated; and, Communications had been established between all stations, the hydrostatic test control room, and all inspection'eams.
Crew Performance:
The inspector observed the following:
The hydrostatic procedure with the latest revision was available and in use by crew members;
The minimum crew requirements had been met; Briefings had been conducted with the crew and the inspection team's; All test prerequisites were met; Appropriate systems, as nee'de'd, were in service; Special test equipment and instrumentation required by the pro-cedure was calibrated, in service,,and manned by test personnel; Testing was being performed as required by the procedure; Crew actions appeared to be correct and timely during the per-formance of the test; and, All data was collected for final analysis, by the cognizant test personnel.
Test Witnessin By direct observation, the inspector witnessed the following:
The manning and conduct of the test at the hydrostatic test pump station and the hydrostatic test control room including the temperature, pressure, and flow monitoring panels;,and'he upper and lower reactor pressure vessel head areas; Water sampling and results for water quality; Reactor pressure vessel temperature greater than 140 F; System pressure at 100 PSIG and temperature at 151 F; System pressure at 650 PSIG and temperature at 152 F; System pressure at 1235 PSIG and temperature at 152 F; Reactor pressure vessel flanges, upper and lower head areas, hydrostatic test pump station, and hydrostatic test control room while at 1235 PSIG and 152 F; Att8ining and holding pressure at 1610 PSIG with temperature at 150 F for a minimum of 10 minutes as a read on the official test gauge in the hydrostatic control room;
Oepressurizing to 1360 PSIG and holding, f'r detailed inspection of all welds 'and'mechanical joints; All assembled inspection teams passing into containment and to
'heir respective areas of inspection; Accompanying inspection teams into containment and inspecting welds on reactor pressure vessel nozzles, nuclear boiler piping, jet pump instrumentatin lines, control rod drive hydraulic lines, feed lines to reactor pressure vessel and main steam line relief.
valve manifold; and, Use of allowable heatup rates and pressure increase and decrease
.rates.
The inspector made independent measurements and calculations in the areas of'emperature, pressure, time, flow, and. rates of change in parameters.
Test results observed by the inspector indicated that acceptance criteria had been met.
g.
~Findin n
The inspector established by records review, by independent calculations and measurements, by direct observations, and by test witnessing, that testing was-conducted in accordance with approved procedures.
The inspector independently verified the acceptability of the test results, and evaluated the performance of the licensee personnel involved in the test.
No items of noncompliance were identified.
4.
Plant Tours The inspector made tours of the facility during the course of the inspection including containment, reactor building, control room, turbine building, steam tunnel, hydrostatic test control room, and hydrostatic pump station.
The inspector visually observed and examined the staging, platforms, ladders, and lighting around all piping, penetration welds, valves, reactor pressure vessel, and temporary connections pertinent to the reactor pressure vessel and associated piping hydrostatic test.
In all areas inspected, observation also included housekeeping, cleanliness controls, storage and protection of components, piping and system No items of noncompliance were identified.
5.
Exit Interview At the conclusion of the site inspection on September 22, 1980, an exit meeting was conducted with 'the licensee's senior site representatives (denoted in Paragraph 1).
The findings were identified and the open items were discussed.
