Pursuant to 10 CFR 50.55a(g)(5), if the licensee determines that conformance with an examination requirement of Section XI of the ASHE Code is not practical for its facility, information shall be submitted to the Commission in support of that determination and a request made for relief from the ASHE Code requirement.
After evaluation of the determination, pursuant to 10 CFR 50.55a(g)(6)(i),
the Commission may grant relief and may impose alternative requirements that are determined to be authorized by law; will not endanger life, property, or the common defense and security; and are otherwise in the public interest, giving due consideration to the burden upon the licensee that could result if the requirements were imposed.
By letter dated August 18, 1994, the licensee, Niagara Hohawk Power Corporation (NHPC or Niagara Hohawk), proposed alter native examinations to the requirements of the ASHE Code,Section XI.
NHPC requested authorization to use ASHE Code Case N-416-1, "Alternate Pressure Test Requirement for Melded Repairs or Installation of Replacement Items by Melding, Class 1, 2, and 3,Section XI, Division 1," and ASHE Code Case N-498-1, "Alternative Rules for 10-Year System Hydrostatic Testing for Class 1, 2, and 3 Systems,Section XI, Division 1," in the NHP-1 and NHP-2 Inservice Inspection Programs.
Our letter and attached safety evaluation dated October 18,
- 1994, approved NHPC's request to use ASHE Code Case N-416-1, with certain provisions;
- however, our review of ASHE Code Case N-498-1 was incomplete at that time.
Our evaluation of NHPC's request to use ASHE Code'Case N-498-1 is contained herein.

~VP~U~TION 2.1 ce see's Re est In accordance. with 10 CFR 50.55a(a)(3),
Niagara Hohawk requests authorization to use ASHE Code Case N-498-1, "Alternative Rules for 10-Year System Hydrostatic Testing for Class 1, 2, and 3 Systems,Section XI, Division 1," in the Nine Hile Point Unit 1 and Unit 2 Inservice Inspection Programs.
Code Case N-498-1 has been approved by ASHE Code Committee but is not currently published in Regulatory Guide 1. 147, "Inservice Inspection Code Case Acceptability ASHE Section XI Division 1."
2.1.1
's o
e t Ident'c t'o Class 1, 2, and 3 systems subject to hydrostatic testing.
2.1.2 AS ode Section XI Re irementsSection XI, Table IMB-2500-1, Category B-P (for Class 1), Table IMC-2500-1, Category C-H (for Class 2),
and Table IMD-2500-1, Categories D-A, D-B, and D-C (for Class 3) contain the requirements for system hydrostatic and leakage testing.
The ASHE Code requires system hydrostatic testing once per 10-year interval at or near the end of the interval.
2.1.3 e 's o
A em tive st NHPC proposed to use the alternative contained in Code Case N-498-1, a system leakage test, in lieu of hydrostatic testing, for Class 1, 2, and 3 systems.
2.1.4 Li ensee's B sis fo elief Niagara Mohawk requests authorization to use Code Case N-498-1 for both NHPl and NHP2.
Code Committee approval indicates that the use of Code Case N-498-1 will provide an acceptable level of safety and quality when applied to pressure testing at both NHPl and NHP2.
Consequently, the proposed Code alternative (Code Case N-498-1) meets the requirement of 10 CFR 50.55a(a)(3)(i) in that an acceptable level of quality and safety is maintained.
Niagara Mohawk is currently developing the schedule for Code required First and Second Interval 10-year hydrostatic testing on Class 3 systems at NHP-2 and NHP-1, respectively.
Depending on the schedule and whether authorization of this Code Case is granted, testing could begin as early as January 1995.
Based on the man-hours required to perform hydrostatic testing on Class 3
systems during the First 10-year Interval at NHP-l, Niagara Mohawk estimates that the use of Code Case N-498-1 would result in a savings of over
$250,000 per 10-year inspection.
Over the lifetime of both plants, NHP-1 would save approximately
$750,000 (3 remaining 10-year inspections x $250,000) and NMP-2 would save
$1,000,000 (4 remaining 10-year inspections x $250,000).
Therefore, proposed Code alternative (Code Case N-498-1) also meets the requirement of 10 CFR 50.55a(a)(3)(ii) in that hydrostatic pressure testing of Class 3 Systems every 10 years would result in an economic hardship without a compensating increase in quality or safety.
2.1.5 BJUISttil Information prepared in conjunction with ASHE Code Case N-498-1 notes that the system hydrostatic test is not a test of the structural integrity of the system but rather an enhanced leakage test.
That this was the original intent is indicated in a paper by S.
H. Bush and R.
R. Haccary, "Development of In-Service Inspection Safety Philosophy for U.S.A. Huclear Power Plants,"
- ASHE, 1971.
Piping components are designed for a number of loadings that would be postulated to occur under the various modes of plant operation.
Hydrostatic testing only subjects the piping components to a small increase in pressure over the design pressure and therefore does not present a significant challenge to pressure boundary integrity since piping dead weight, thermal expansion, and seismic loads, which may present far greater challenge to the structural integrity of a system than fluid pressure, are not part of the loading imposed during a hydrostatic test.
Accordingly, hydrostatic pressure testing is primarily regarded as a means to enhance leakage detection during the examination of components under pressure, rather than as a measure to determine the structural integrity of the components.

NHPC requested approval for the implementation of the alternative rules of ASHE Section XI Code Case N-498-1, dated May ll, 1994, "Alternative Rules for 10-Year System Hydrostatic Testing for Class 1, 2, and 3 Systems" for 10-year hydrostatic testing of Class 1, 2, and 3 systems.
ASHE Code Case N-498, "Alternative Rules for 10-Year System Hydrostatic Testing for Class 1,
and 2
Systems," is applicable to Class 1 and 2 systems and was previously approved by the NRC in Regulatory Guide 1.147, Rev.
11.
The rules for Code Class 1
and 2 in N-498-1 are unchanged from N-498.
The staff found N-498 acceptable because the alternative provided adequate assurance and because compliance with the specified requirements would result in hardship or unusual difficulty without a compensating increase in the level of quality and safety.
Therefore, this evaluation applies to Class 3 systems.
ASHE Code Case N-498-1 encompasses Class 3 components and specifies requirements for Class 3 components that are identical to those for Class 2
components.
In lieu of 10-year hydrostatic pressure testing at or near the end of the 10-year interval, Code Case N-498-1 requires a visual examination (VT-2) be performed in conjunction with system leakage testing at nominal operating pressure and temperature.
Currently, licensees incur considerable time, radiation dose, and dollar resources'arrying out hydrostatic test requirements.
A significant amount of effort may be necessary (depending on system, plant configuration, ASHE Code class, etc.) to temporarily remove or disable code safety and/or relief valves to meet test pressure requirements.
The safety assurance provided by the enhanced leakage gained from a slight increase in system pressure during a
hydrostatic test may by offset or negated by the following factors:
having to gag or remove code safety and/or relief valves, placing the system (and thus the plant) in an off-normal state, erecting temporary supports in steam lines, possible extension of refueling outages, and resource requirements to set up testing with special equipment and gages.
Class 3 systems do not normally receive the amount and/or type of nondestructive examinations that Class 1 and 2 systems receive.
While Class 1
and 2 system failures are relatively uncommon, Class 3 leaks occur more frequently and the failure mode typically differs; Based on a review of Cl'ass 3 system failures requiring repair for the last 5 years in Licensee Event Reports and the Nuclear Plant Reliability Oata System databases, the most common causes of failures are erosion-corrosion (EC), microbiologically induced corrosion (HIC), and general corrosion.
Licensees generally have programs in place for prevention, detection, and evaluation of EC and HIC.
Leakage from general corrosion is readily apparent to inspectors when performing a VT-2 examination during system pressure tests.
The industry indicates that experience has demonstrated that leaks are not being discovered as a result of hydrostatic test pressures propagating a preexisting flaw through wall.
They indicate that leaks in most cases are being found when the system is at normal operating pressure.
Giving consideration to the minimal amount of increased assurance provided by the increased pressure associated with a hydrostatic test versus the pressure for the system leakage test and the hardship associated with performing the ASME Code required hydrostatic test, the staff finds that compliance with the ASME Code Section XI hydrostatic testing results in hardship and/or unusual difficulty for the licensee without a compensating increase in the level of quality and safety.
Accordingly, the licensee's proposed alternative, use of ASME Code Case N-498-1 for ASME Code Class 1, 2, and 3 components, is authorized for NMP-1 and NMP-2, pursuant to 10 CFR 50.55a(a)(3)(ii).
NMPC's alternative is authorized until such time as ASME Code Case N-498-1 is pub-lished in a future revision of Regulatory Guide 1.147.
At that time, if the licensee intends to continue to implement this Code case, the licensee is to follow all provisions in ASME Code Case N-498-1, with limitations issued in Regulatory Guide 1. 147, if any.
3.0
~CONC Ull HB The staff evaluated the information provided by the NMPC in support of its request for relief.
Based on the information submitted, the alternative for hydrostatic testing contained in the licensee's proposal is authorized pursuant to 10 CFR 50.55a(a)(3)(ii) as compliance with the specified hydrostatic testing requirements would result in hardship or unusual difficultywithout a compensating increase in the level of quality and safety.
