1 NIAGARA M0 HAWK POWER CORPORATION NINE MILE POINT - UNIT 2 DOCKET NO. 50-410 Final Report for a Problem Concerning Bolted Flanged Piping Joints (55(e)-84-28) 4 Description of the Problem The problem concerns the' installation of Quality Assurance Category I-bolted flanged piping ' joints by ITT Grinnell> without a documented procedure.
Criterion V states, in part, that the activities affecting. quality shall be prescribed by documented instructions and procedures.
ITT Grinnell Bolting Procedure No. FQC 4.2-25-4 was approved on May 24, 1984..
Prior to this procedure, no formal procedure existed establishing requirements for installation and inspection of bolted Category I 2
flanged piping joints.
i.
Analysis of Safety Implications A detailed analysis of safety implications was not perfomed to. determine the effect of perfoming ' Category I work without a documented procedure.
ITT Grinnell is an ASME III certificate holder and installer and is required to meet applicable ASME Code and specification requirements.
.However, a
possibil.ity existed that the performance of Category I. work without a
' documented procedure could have increased the possibility of non-conformance with ASME III and hence could have adversely affected tha safety of operations of the plant.
To prelude this possibility, the corrective actions outlined 4
below have been or will be taken.
l Corrective Actions 1.
ITT Grinnell has infomed Stone and Webster that it has - taken or will take the following corrective and preventive actions:
a.
. Bolting Procedure No. FQC-4.2-25 was revised on July 11, 1984, to delineate inspection attributes for previously bolted joints, b.
Since May 24, 1984, all new bolted joints have been installed in.
accordance with FQC-4.2-25.
ITT Grinnell Quality assurance performed a surveillance on September 14, 1984, to verify compliance.

c.
The service water lines have been walked down by Quality Control personnel in order to identify previously bolted joints that required rework.
This was done prior to release for hydro testing.
Engineering has issued new planner packages for joints requiring rework and - the rework has been accomplished in accordance with the requirements of. FQC-4.2-25, Revision 5.
Quality Assurance performed a review of service water documentation on September 14, 1984, to verify that previously accepted bolted joints now have the proper documentation to indicate that FQC-4.2-25 has been implemented
. properly.
d.
Rework of the remaining previously bolted joints will be done in accordance with the Boundary Identification Package turnover schedule.
2.
Stone and Webster Quality Assurance is revising the existing surveillance check list to include the bolting criteria in its surveillances.
This will be completed by December 15, 1984 f
