i Results: The licensee has developed appropriate programmatic controls for NDE
'
activities which are fully consistent with the requirements of Sections III and V of the ASME B&PV Code. Based on the visual inspection of 18 welds, review of radiographic examination film for 9 welds, and review of 46 NDE records, the licensee has effectively implemented the NDE program.
A satisfactory quality assurance program for the control of design changes and modifications was found. Quality assurance was found to be performing audits and surveillance of design changes and modifications, as well,as in-line reviews of modifications. Some engineering errors in classification of modification quality levels resulted in quality assurance not performing all required reviews of modifications. The misclassification of modifications was identified as a noncited violation (see paragraph 3).
Inspection Conducted September 11-15, 1989 (Report 50-499/89-37)
Areas Inspected: Routine, unannounced inspection of the QA program for design changes anc modifications.
Results: A satisfactory QA program for the control of design changes and modifications was found.

Nondestructive Examination Activities (57050 through 57090)
The objective of this inspection was to verify that the licensee has developed and implemented a' program relating to control of' nondestructive examination (NDE) activities that is in confonnance with connitments in the Final Safety Analysis Report (FSAR).
.The-inspector reviewed the licensee's program for controlling NDE activities to assure that examinations are controlled and accomplished by qualified personnel using qualified procedures in accordance with applicable codes, standards, specifications, criteria, and other special requirements. The documents for controlling the NDE program are listed in Attachment 1.
These documents provide the instructions for: visual examination of welds, liquid penetrant examination, magnetic particle examination, ultrasonic thickness measurement, radiographic examination, and qualification and certification of nondestructive examination personnel. The inspector found that appropriate programmatic controls for NDE activities had been developed which were fully consistent with the. requirements of Sections.III and V of the ASME B&PV Code for performing and documenting the examinations.
The inspector selected the welds listed in Attachment 2 from the maintenance and modification activities and performed an inspection of the completed
,
NDE documentation. The review included 18 visual examinations, 8 liquid penetrant examinations,11 magnetic particle examinations, and 9 radiographic examinations. In addition to reviewing the visual examination records, the welds were visua.lly inspected by the inspector. The radiographic film was also reviewed by the inspector for those welds that were radiographer.
On the basis of this inspection, the licensee was found to be effectively performing and documenting required nondestructive examinations during maintenance and modification activities.

Design Changes and Modifications Program (37702)
!
The objective of this-inspection:is to ascertain whether the licensee is implementing a quality assurance (QA) program relating to the control of design changes and modifications that is in conformance with regulatory-requirements, commitments ~in the FSAR, and industry guides and standards.
In this regard the inspector reviewed the current quality' assurance program description in Chapter 17.2 of the FSAR, the Operations Quality
. Assurance Plan, Revision 7, dated June 1, 1989, and the following
. procedures:
ASME Section XI Repair / Replacement Program, IP-3.07Q, Revision 4, dated August 8, 1989 Plant Modifications, IP-3.1Q, Revision, 6, dated July 28, 1989 Design Control, IP-3.19Q, Revision 1, dated May 21, 1988 Engineering Change Notice Package, IP-3.24, Revision 3, dated July 28, 1989 The inspector found that GA involvement in design changes and modifications.was satisfactory. This was based on the inspection of audit (Audit 88-43) and surveillance activities (Surveillance 89-031 -062,
-104. -194, and -218) performed recently by the licensee.
In addition, Modification Design Packages (MDPs)g Change Notice Packages (ECNPs) a the in-line QA review of Engineerin was evaluated by perfoming a detailed review of a sample of ten ECNPs and ten MDPs.
In the inspection of the MDPs, it was found that two Modification Change Notices (MCNs) were misclassified by engineering in regard to the applicable quality level. The MCNs were 88-188 AA (associated with a modification to relocate the locse parts monitoring system on the steam generators) and 87-091 AA (associated with the installation of mid-loop operationinstrumentation). As a result of the misclassification by engineering of HCN 88-188 AA as quality level 9 (nonsafety-related)
instead of the applicable quality level 1 (safety-related), the MCN was not submitted for the QA review that was required by Procedure IP-3.1Q.
MCN 87-091 AA was misclassified as quality level 7 instead of 2, but was submitted for 0A review because both of these quality levels are required by IP-3.10 to be reviewed by QA.
In both of the examples, review of the associated work packages by the Authorized Nuclear Inservice Inspector (ANII) wes obtained. This review occurred because the staff generating the work package noted that an American Society of Mechanical Engineers (ASME) Code boundary was being modified. The normal sequence of events would have been for the MDP to have identified that an ANII interface was required.

After this apparent violation of Procedure IP-3.10 and Specification 0,
9A010GS1001 was discovered'by the inspector, the licensee identified it on Problem Report 890683. The inspector found that the licensee has established-a program to determine-the. scope of this problem and to establish corrective
<
actions. :As part of.the corrective action, the licensee has. established that any misclassified MCN or MDP will.be reclassified and an' evaluation'
performed:of the modification to ensure that the appropriate QA-program and quality control inspections were satisfied.. A Notice of Violation is not being issued because the criteria of Section V.A. of'the NRC's Enforcement Policy have been met. >

4.
Exit Interview
An exit interview was conducted on September 15, 1989, with those personnel denoted in paragraph'1. At the exit interview, the inspectors summarized the' inspection findings. No information was presented to the inspectors that was. identified by the licensee as proprietary.
