indicated that they would preform a demonstration to support all the MT examinations performed on RPV Studs and Nuts at this site which are not consistent wi+,h the cod Pending the NRC review of this demonstration, this matter will be identified as unresolved item 50-413,414/89-08-01: "MT Demonstration".

(2) ASME,Section XI, Paragraph IWA-4500, requires that repairs be examined by the method that detected the flaw that required repair. This requirement is implemented in Procedure NDE-25, Revision 12, Paragraph 12.2.4.1 (c) and NDE-35, Revision 10, i Paragraph 17.4. This requirement is not implemented in NDE-12 or NDE-98. The licensee indicated that this requirement is covered in other documents ia their program. The licensee indicated that they would amend the above procedures to uniformly address this requirement. This matter will be identified as inspector followup item 50-414/89-08-02: "ISI Baseline Inspection Method".

(3)' The licensee was unable to provide objective quality evidence of calibration for temperature instrument A0668 for January 1988. In addition, the licensee could not provide the spectrum analysis for transducer Nos. M18416 and M18423. The licensee indicated that they would make the above documents available at a future inspection. This matter will be identified as inspector followup item 50-414/89-08-03: " Unavailable ISI Records".

l (4) Relative to the observation of MT Examination the inspector nated the following:

(a) The examiners used a puffer ball to remove excess particles during the examination with excessive air flow forc (b) Light gray particles were used on bright steel which did not provide good contrast between the steel surface and the particles. When the inr %ctor asked the examiners why they chose gray parc1cles, they stated that the red particles were too mess l l

(c) The examination record for the two welds the l inspector observed being examined indicated only one certified examiner performed the examination, when in point of fact, there were two examiners !

who each only performed portions of each {

examination on each weld. The licensee corrected l the records for the two welds discussed above and ;

identified and corrected two additional example !

(d) The certification of calibration for the yoke used to perform the MT examination, observed by the inspector, did not specify how the calibration was accomplished (Was ten pound lift test performed? Was the weight traceable to the National Bureau Of Standards?). The licensee corrected the report reflecting the calibration '

method and the test weight employe (e) Items (a)-(d) above were the subject of licensee training given to all the DPC MT examiner (f) A valve, immediately upstream, of the two welds, the inspector observed being MT examined was tagged "2SV27A". The isometric drawing (CN-25V-3 R10) the examiners had to locate and identify the welds to be examined, identified the the valve as "2SV027". When asked, the examiners could not explain why the discrepancy. Further investigation revealed that the valve tag number corresponded to the sy3 tem flow drawing (CN-2593-1.0 R9) identification. The licensee indicated that they would provide training in this area and correct the isometric drawings to reflect the correct valve numbers. This matter will be identified as inspector followup item 50-413,414/89-08-04: " Valve Identification."

(5) Notes on sketches in DPC NDE Manual copy 31, Procedure NDE-12 due to the reproduction process and the size of the print was not legible. The licensee committed to correct all the illegible figures in each NDE procedure at the NEXT REVISION of each NDE procedur (6) DPC ASME,Section XI Manual, Section E, " Repairs And Replacements And Maintenance Activities" is the Licensees' program procedure for the implementation of the ASME B&PV Code,Section XI, Article <

contains all the items included in ASME B&PV Code,Section III, Subsection NB, Paragraph NB-2121(b). Items that are included in NB-2121(b) and section "E" of the DPC ASME,Section XI Manual, which are, therefore, not included in the DPC Repair and

ASME B&PV Code,Section III, provides rules covering the requirements for strength and pressure integrity, the failure of which would violate the pressure retaining boundary. ASME B&PV Code,Section XI, provide rules for Inservice inspection an Inservice testing of systems for light water cooled nuclear power plant integrity and operational readiness, the loss of which would adversely impact the shutting down of the reactor or mitigation of an acciden The scope of ASME B&PV, Sections III and XI, are different. The items excluded by Section III are items that do not form the pressure boundary. By the same logic, items excluded by Section XI should not form part of the pressure boundary and should not affect the operational readiness of components necessary for reactor shutdown and mitigation of an acciden Clearly shafts, bearings, bushings, and springs necessary for operational readiness of important plant components, should not be excluded from the Section XI Replacement Program. The absenting the above items from the program would exclude them from the suitability evaluation required for Section XI re?lacement items delineated in IWA-7220. This matter will be the subject of a future inspectio (7) There was insufficient information in the relief requests examined to support the relief requested. After drawing review, review of photographs and a walkdown inspection, the inspector was able to verify that the relief requests, though sketchy, were accurate. The inspector discussed the above with the licensee indicating that in the future they should include enough information to support the request for relief. The licensee indicated that they would supplement their existing relief requests with sufficient information to support those request (8) The inspector noted, during his inspections in the lower level of the Unit Two containment building, that both the licensee's personnel and contractor personnel climbed on anything convenient in i order to reach their work location. Items employed for personnel support included instrument lines, lines to gage glasses, small bore pipe supports and struts, small valves, and cable trays containing cables thus providing a hazard to the equipment important to safety and to personnel . In addition, contrary to the licensee's documented safety program, none of the licensee or contractor personnel, observed by the inspector, had or were using safety belts when working more than six feet above the floor. This matter will be examined in more

program for the protection installed equipment is consistant with the Licensees' commitments and regulatory requirements. Thi t. matter will ,

be identified as Unresolved Item 50-413, 414/89-08-05: " Protection of installed equipment."
