Feewater System Pipe Replacement, Unit 1
I a.
The inspector reviewed the below listed radiographs of circum-
)
ferential welds in the feedwater system which were produced as a
!
result of pipe replacement for portions of this system.
The welds j
were radiographer by a contractor for the licensee with some of the I
radiographs-being originally interpreted and rejected by the l
contractor.
The licensee's qualified radiographic film interpreter subsequently re-evaluated the radiographs which had been rejected due to possible weld flaw indications.
The licensee's film interpreter, in some case, accepted contractor rejected welds based on the applicable code and acceptance criteria. The applicable Code is ANSI l
B31.1.
Also, in at least two cases, the licensee's film interpreter
!
identified radiographs that had been accepted by the contractor which had rejectable flaw indications.
Following these findings,100% ~of i
the film was re-eveluated by the licensee's film. interpreter.
This
'
inspector reviewed radiographs that were originally rejected by the contractor and subsequently accepted by the licensee and in addition
'
selected a sample of the remaining accepted weld radiographs for review.
The inspectors review of the radiographs selected indicated that the welds were acceptable under the applicable ' acceptance criteria.
b.
The below listed radiographic film was reviewed to determine if radiographic quality was in accordance with applicable Code requirements and to specifically verify the following: penetrometer type, size and placement; penetrometer sensitivity; film density and density variation; film identification; film quality; and weld coverage.
Also, the inspector reviewed the examination records for l
I the listed welds to determine compliance with procedure requirements for examination records and to determine if disposition of the welds radiographer was in compliance with applicable Code and specification
!
requirements.

written procedures have been established for initiating requests for routine and emergency maintenance; criteria and responsibilities have been established for review and approval of maintenance requests including emergency maintenance requests; criteria and responsibilities have been established that form the basis for designating the activity as safety-related or non safety-related; criteria and responsibilities have been designated for performance of inspections and maintenance activities; provisions and responsibilities have been established for the identification of appropriate inspection hold points related to maintenance activities; methods and responsibilities have been designated for performing functional testing of structures, systems, or components following maintenance work and/or prior to their being returned to service; administrative controls for' maintenance activities require that applicable records will be prepared, assembled, and reviewed for transfer to records storage; responsibility has been established to assemble and review the maintenance records for transfer to record storage; a program has.been established for reviewing completed corrective maintenance records to assess the adequacy of the preventive maintenance program, to identify repetitive failures of parts and components, and to identify design deficiencies; work control procedures have been established to require special authorization for activities involving welding, open flame, or other ignition sources and take cognizance of nearby flammable material, cable trays, or critical process equipment; and, revisions to technical specifications have been incorporated into procedures and included in the master program.
(2) The above listed procedures, relative to the licensee's preventive maintenance program, were reviewed to confirm that a written preventive maintenance program for safety-related structures, systems, and components has been established that includes:
responsibility for the program; master schedule for

,
l preventive maintenance; documentation and review of completion j
of preventive maintenance activities; responsibilities and-
methods for establishing preventive maintenance frequencies-
~
L responsibility for periodic upgrading based on system or i
component failures; and, methods for incorporating revisions to technical specifications into procedures and the master program.
-(3) The above listed procedures, relative to. equipment control, were reviewed to establish that methods and responsibilities for equipment control have been defined and specifically to confirm that: procedures have been established to specify that the operating staff grants permission to release equipment or systems for maintenance; equipment that is environmentally qualified should be identified as such prior to maintenance and sufficient contro!s should exist to ensure it is returned to that status upon reassembly; procedures and rernonsibility have been established for returning equipment to service; and, revisions to Technical Specifications have been incorporated
into procedures and included in the master program.
i
(4) The above listed procedures, relative to special proceres, were
'i reviewed to confirm that responsibilities have been assigned to assure that the requirements of the administrative controls will l
be accomplished and that the administrative controls for special
)
processes have been established as follows: a requirement that only qualified procedures will be used; a requirement that only j
qualified personnel will be used; a requirement that a current j
file of special processes will be maintained to include qualification records of procedures and personnel; and, criteria to establish when the use of mock-ups or other special training will be required, j
(5) The above listed procedures relative to cleanliness controls were reviewed to verify that: procedures have been developed for l
cleaning safety-related components and systems and that i
responsibilities for implementing this requirement has been.
j established; procedures have been established for maintaining i
the cleanliness of previously cleaned systems and that responsibilities for implementing this requirement has been established; and, the cleanliness classifications of plant systems have been established.
During the review of procedures for cleanliness controls for plant systems / components, the inspector noted that no basic
,
specification had been developed to outline specific cleanliness
'
requirements after maintenance has been completed.
Upon discussions with plant personnel, it was determined that the quality assurance group did have guidelines, however, these
____
.
guidelines could not be traced to a specific specification.
~
Further, the licensee had previously identified this area as needing some specific specification bases and had initiated an Emergency Work Request (EWR) on Septemter 17, 1985, requesting resolution from the station engineering department.
However, due to EWR form changes at the time of submission, and i
subsequent rotational assignment of the. EWR within the Engineering department, the resolution has not yet been completed.
Pending the licensee's adequate resolution of this oversight and review of the resolution by the NRC, this item will be identified as Unresolved Item 50-338, 339/87-18-01, Specification for System and/or Component Cleanliness Following
,
Maintenance.
(6) The above listed procedures, relative to housekeeping controls, were reviewed to confirm that administrative controls and responsibilities for general housekeeping have been established to include defining housekeeping zones and controlling
'
housekeeping during work activities, b.
In ' order to determine whether the maintenance program is being implemented in accordance with regulatory requirements and to evaluate the effectiveness of the program on important plant equipment and to assess the ability of the maintenance staff to conduct an effective maintenance program, a selection of both i
completed and working maintenance work order packages and associated I
documentation was reviewed.
The specific work order packages and i
associated documentation are recorded in the following subparagraphs.
l (1) The below listed work order packages were reviewed to determine whether: the cause of the failure was evaluated and adequate i
corrective action was taken to reduce the probability of
'
recurrence; the procedures specified in the maintenance package were adequate for the scope of the maintenance performed; and vendor maintenance recommendations, if used, were correctly translated into or referenced by the maintenance procedures.
