Inspection Demonstration The inspector witnessed a
demonstration of an ultrasonic examination technique that the licensee stated would be submitted as an alternate examination for the surface examination required in Table IWB-2500-1 of ASME Section XI for. Reactor Vessel Nozzle-to-Safe End welds by Item 85.10, examination Category 8-F.
The demonstration consisted of manual scans utilizing 50/70-degree tandem-beam refracted longitudinal wave search units and with 45-degree shear wave (calibrated to the 8/8 mode)
search units to detect flaws oriented parallel and transverse to the weld plane.
The couplant employed was "Ultragell II".
The scans were made on a
mock-up simulating a 29-inch diameter x 2.750-inch wall reactor vessel nozzle, nozzle clad, reactor coolant pipe weld, and reactor coolant piping material with artificially created ID and OD axial and circumferential oriented surface indications.
A portion of the indications were of a
length acceptable to the ASME BSPV Code Section XI acceptance criteria for surface indications in a material thickness represented by the mock-up.
The remainder were of a length that exceeded that acceptance criteria.
All of the indications were detectable by one or both of the search units.
Using the indication depths given the inspector by the licensee, all of the indications were acceptable to the ASME BSPV Code Section XI volumetric acceptance criteria.
Therefore, the demonstration showed that Code acceptable surface indications of a size smaller than the size that would be rejected by Code paragraphs IWB-3514.2(b)
and IW8-3514.3(b)
and Table IWB-3514-2, could be detecte t 1H
The demonstration technique differs from the intended inspection on the reactor vessel nozzles in that the vessel inspections will be automated vice manual, primary water will be used as the couplant vice Ultragell II, and equipment employing electronic enhanced DAC vice standard DAC will be used.
8.
Inservice Testing Of Pump and Valves (61700B)
The inspector was requested, by resident inspectors, to review the testing of the check valves listed in following relief requests.
Relief Re uest Safety Injection Relief Request Nos.
7, 8, 9, 15 5 16 Chemical and Volume Control Relief Request Nos.
10, 11,
& 12 Auxiliary Coolant, Residual Heat Removal Relief Request No. 2.
The residents concerns'ere that the relief requests all stated that the check valves function was to prevent reverse flow (that is to say that those valves must close to meet their function), but the proposed alternate test was to verify that the valves would open.
The inspector discussed this with the licensee and determined that the valves in the below listed relief requests are now tested to both open and to close as documented in Generic Relief Request No. 3.
Relief Re uests Safety Injection Relief Request Nos. 7, 8, 9, 15 5 16.
The licensee indicated that the remaining valves in the below listed relief requests have a safety function to open during "The" accident.
The licensee indicated that they could not state for certain whether those valves would be required to close during "an" accident as defined by ASME Section XI.
Relief Re uest Chemical 5 Volume Control Relief Request Nos.
10,
5 12 Auxiliary Coolant, Residual Heat Removal Relief Request No. 2.
The licensee indicated that they would re-evaluate the testing requirements for those valves.
Pending NRC review of the licensee'e-evaluation.
This matter will be identified as Unresolved Item 250, 251/86-15-01:
"Check Valve Testing Adequacy".
