RESPONSE TO NRC COMPLIANCE BULLETINNO. 87-02 The following sections provide specific detail for each of the Bulletin 87-02 action items:
Action 1:
Describe a) the characteristics currently examined during receipt inspection of fasteners (i.e., head markings for grade and manufacturer symbols, review of certified material test report or certificate of conformance), and b) internal controls utilized during storage and issuance from stock to ensure the appropriate use of fasteners.
CPRL Res onse Inspections are performed in accordance with applicable receipt inspection procedures (OQA-002, Receipt Inspection, and OQA-003, Material Verification). Specific inspection characteristics include dimensions as specified by purchase order, head markings as required by material specification and tolerances as specified by ANSI B18.2.1 for square and hex screws and bolts and ANSI B18.2.2 for square and hex nuts.
Vendor supplied documentation (i.e., certificates of compliance and certified material test reports) are reviewed for compliance to applicable purchase order and material specifications.
Additionally, nondestructive and destructive testing may be performed as described by OQA-003, Material Verification.
Procedures require that material control (stores) personnel receive, package, and store fasteners in accordance with the storage and maintenance sheet.
Storage levels are assigned by Engineering Technical Support personnel.
These storage levels are indicated on the storage and maintenance data sheets and the supply inventory system data base.
Prior to use of fasteners, procedures require that the equipment data base system (EDBS), technical manuals, supply inventory system (SIS),
consumables list, and procedures and drawings be reviewed for proper application of replacement parts. If the repair part or consumable (fastener) is not listed on the EDBS reference parts listing for that component, on the approved consumables list, on an approved procedure, or on the SIS screen for that application, an engineering evaluation must be performed on that part/consumable prior to its use.
Changes, including field revisions and equipment substitutions in safety-related systems, are subject to control measures commensurate with the constraints applied to the original design.
Changes are reviewed and approved by the organization that approved the original design or other responsible
,. organization.
In addition, the part used is identified by CPRL part number and the purchase order number for each installation package thus providing traceability to manufacturer's documents.
(5362AWS/bmc )
Select a minimum sample of ten (10) nonsafety related fasteners (studs, bolts, and/or cap screws) and ten (10) safety-related fasteners (studs, bolts, and/or cap screws) from current, in-use stock.
The sample is to be obtained by the licensee with the participation of an NRC inspector.
Fasteners procured to meet the following chemical and mechanical properties are of interest:
A-193 Grades B7, B8, and BV16; SAE J029 Grades 5 and 8; A-009; A-325 Types 1, 2, or 3; A-350 Grades BB, BC, BD; A-090; A-.320 LTM;A-307; A-563; or equivalent.
CPRL Res onse Refer to our response for Action 3.
For the selected sample of fasteners in Item 2, include a sample of typical nuts that would be used with each fastener (one-for-one).
In particular, nuts purchased to the chemical and mechanical specifications of A-190 are of interest.
CPRL Res onse A total of 38 nuts and bolts were sampled, 27 of which are safety-related.
The remaining 11 are "structural" nuts and bolts which are not used in plant systems.
Please note that SHNPP uses safety-related fasteners for any plant system and has no nonsafety classification for plant fasteners.
The sampling of the "structural" fasteners as SHNPP nonsafety related fasteners was concurred'with by the NRC inspector participating in the sampling activity.
Chemical testing shall be performed on all samples.
Mechanical testing shall be performed on each safety-related fastener.
Hardness testing shall be performed on each nut and nonsafety-related fastener.
Alltesting shall be performed by a laboratory which the licensee has qualified for this type of testing and appears on the licensee's approved vendor list.
Testing performed shall be done in accordance with the requirements of the fastener's specification, grade, and class, and the test shall evaluate the ultimate tensile strength, hardness, and chemical properties as required by the fastener's specification, grade, and class.
Each sample shall be tagged with the sample's ID number.
CPRL Res onse Mechanical testing of each safety-related fastener and hardness testing for each nut and nonsafety-related fastener samples was performed by CPRL's Metallurgy Laboratory which falls under CPRL's Corporate Quality Assurance Program and meets the qualifications necessary to perform the testing.
Per discussions with Mr. J. T. Conway (NRC) on November 18, 1987 and Mr. P. E. Fredrickson (NRC-Region II) on December 1, 1987, the NRC concurred with the use of the CPRL Metallurgy Laboratory.
Chemical testing of the samples was performed by National Spectrographic Laboratories which is on CPRL's approved vendor list.
(5362AWS/bmc)
The testing program was in accordance with ASTM-approved methods required by the fastener's specification, grade, and class.
Each sample was provided a unique identification number.
The results of all tests, together with supporting information, are to be reported to the NRC utilizing the format shown in Attachments 1 and 2 of this bulletin. Include the names and addresses of suppliers and manufacturers of safety-related fasteners and, to,the extent possible, of nonsafety related fasteners.
For any fastener found out of specification, provide an evaluation of the safety significance including consideration of the most limitingapplication.
CPRL Res onse Results of the CPRL Bulletin 87-02 testing are presented on Table 1, "SHNPP Fastener Testing Data Summary." Table 1 is formatted in the manner suggested by the bulletin. The fasteners are categorized by the applicable ASTM specification and are listed by their unique identification number assigned at the time of sampling.
Results which do not meet the applicable specification requirement are denoted by an asterisk (+).
Table 2 lists the fastener supplier and manufacturer names and addresses.
Two of the 38 SHNPP fasteners (Sample Nos. HNP-SA193-B8-25 and HNP-SA193-B8M-08) were deter mined to be out of compliance with their applicable ASTM specifications.
Sample No. HNP-SA193-B8-25%as procured as SA193, Grade B8 material without a class designation.
The material is a 1/2 inch by 13 thread threaded rod designated for use in a variety of safety-related system applications.
The CMTR received with this rod identified it as SA193, Grade B8, Class 1 material; however, testing done per the requirements of this bulletin identified it as Class 2 material.
Either class is acceptable for the CPRL applications of this rod since Class 2 is a higher strength material than Class I. This sample met the ASTM requirements for Class 2 except for hardness (a measured value of 37 Rockwell C scale versus a code allowable maximum of 35 Rockwell C). The difference between measured and allowable hardness is minimal and has no significant effect on the ability of the material to perform its safety-related function..This is supported by its higher strength Class 2 properties where Class 1 strength is acceptable.
Testing of sample No. HNP-SAI93-B8M-08 demonstrated that it meets its code requirements except for hardness.
The testing measured hardness as 20 Rockwell C scale versus the code allowable maximum of 96 Rockwell B scale.
(The ASTM standard indicates that a 96 Rockwell B scale is approximately equal to 17 Rockwell C scale although direct correlation is not recommended.)
This material is used in a variety of safety-related system applications; however, there are no applications where the increased hardness would significantly effect the ability of the material to perform its safety-related function. Therefore, it is CPRL's position that the fasteners are acceptable for use in safety-related applications, and no further actions are required regarding these fasteners.
(5362AWS/bmc)
Based on the results of the testing and review of current procedures, describe any further actions being taken to ensure that fasteners used in the plant meet the requisite specifications and requirements and that the operability of safety-related plant components is not affected.
CP&L Res onse Based on the results of CPRL's review and testing program, we believe that our receipt inspection and material handling programs are adequate and meet or exceed the applicable requirements.
No further actions are therefore considered to be necessary.
