3.1-5 Amendment No.)*<
steels such as ASTM A302 Grade B parent material of the H. B. Robinson Unit
No. 2 reactor pressure vessel are well documented in the literature.
Generally, low alloy ferritic materials show an increase in hardness and other
strength properties and a decrease in ductility and impact toughness under
certain conditions of irradiation. Accompanying a decrease in impact strength
is an increase in the temperature for the transition from brittle to ductile
fracture.
A method for guarding against fast fracture in reactor pressure vessels has been
presented in Appendix G, "Protection Against Non-Ductile Failure," to
Section III of the ASME Boiler and Pressure Vessel Code. The method utilizes
fracture mechanics concepts and is based on the reference nil-ductility
temperature, RTNDT.
RTNDT is defined as the greater of: 1) the drop weight nil-ductility
transition temperature (NDTT per ASTM E-208) or 2) the temperature 60'F less
than the 50 ft-lb (and 35 mils lateral expansion) temperature as determined
from Charpy specimens oriented in a direction normal to the major working
direction of the material. The RTNDT of a given material is used to index
that material to a refeence stress int it factor curve (KIR curve) which
appears in Appendix G of A the ASMECde. The KIR curve is a lower bound of
dynamic, crack arrest, and 6tatic fracture toughness results obtained from
several heats of pressure vessel steel. When a given material is indexed to
the KIR curve, allowable stress intensity factors can be obtained for this
material as a function of temperature. Allowable operating limits can then be
determined utilizing these allowable stress intensity factors.
The Certified Material Test Reports (CMTRs) for the original steam
generators provided records of Charpy V-notch tests performed at +10*F.
Acceptable Charpy V-notch tests of +10*F indicate RTNDT is at or below
this temperature. The steam generator lower assemblies were replaced in
1984 and the material tests results indicate the highest RTNDT is 60*F or
below. The ASME code recommends that hydrostatic tests be performed at a
temperature not lower than RTNDT plus 60F*, thus the pressurizing
temperature for the steam generator shell is established at 120*F to
provide protection against nonductile failure at the test pressure.
3.1-6 Amendment No.)9f
V-notch 30 ft-lb temperature (A RT ) due to irradiation is added to the
original RTNDT to adjust the RTNDT for radiation embrittlement. This adjusted
RTNDT (RTNDT initial +ARTNDT) is utilized to index the material to the KIR
curve and in turn to set operating limits for the nuclear power plant which
take into account the effects of irradiation on the reactor vessel
materials. Allowable pressure-temperature relationships for various heatup
and cooldown rates are calculated using methods (2) derived from Appendix G to
Section III of the ASIME Boiler and Pressure Vessel Code. The approach
specifies that the allowable total stress intensity factor (KI) at any time
during heatup or cooldown cannot be greater than that shown on the KIR curve
in Appendix G for the metal temperature at that time. Furthermore, the
approach applies an explicit safety factor of 2.0 on the stress intensity
factor induced by pressure gradients.
Following the generation of pressure-temperature curves for both the steady
state and finite heatup rate situations, the final limit curves are produced
in the following fashion. First, a composite curve is constructed based on a
point-by-point comparison of the steady state and finite heatup rate data. At
any given temperture, the allowable pressure is taken to be the lesser of the
two values taken from the curves under consideration.. The composite curve is
then adjusted to allow for possible errors in the pressure and temperature
sensing instruments.
The use of the composite curve is mandatory in setting heatup limitations
because it is possible for conditions to exist such that over the course of
the heatup ramp the controlling analysis switches from the O.D. to the I.D.
location; and the pressure limit must, at all times, be based on the most
conservative case. The cooldown analysis proceeds in the same fashion as that
for heatup, with the exception that the controlling location is always at the
I.D. position. The thermal gradients induc'ed during cooldown tend to produce
tensile stresses at the I.D. location and compressive stresses at the O.D.
position. Thus, the I.D. flaw is clearly the worst case.
As in the case of heatup, allowable pressure temperature relations are
generated for both steady state and finite cooldown rate situations.
Composite limit curves are, then constructed for each cooldown rate of

Pressurized Thermal Shock
In accordance with the revised Pressurized Thermal Shock (PTS) Rule, 10 CFR 50.61, effective June 14, 1991, the reactor vessel beltline materials were evaluated to determine the impact of the revised rule. A summary of the pertinent data required by revised Section 50.61(b)(1) for both the current date and the HBR2 Operating License expiration date is included in the table of this Enclosure 6.
The PTS rule requires calculation of RTPTS values for all beltline materials for both (1) End-Of-License (EOL) and (2) the time of submittal. August of 1993 was chosen as the time of submittal to coincide with the planned Technical Specification submittal of updated Pressure - Temperature limit curves.
The calculation results show the upper circumferential weld joint (Weld 10-273) to be the most limiting beltline material for PTS considerations. However, as shown in the attached table, none of the calculated RTPTS values exceed the 10 CFR 50.61 screening criterion. Therefore, as concluded in 1991, a response to the NRC by December 16, 1991, in accordance to the PTS rule, was not required.
The methods for calculation of RTPTs do not currently permit the use of plant specific materials surveillance program data, as allowed by the methods for calculating RTNDT . Because the upper weld (10-273) has been demonstrated as applicable to the surveillance program, plant specific data was used for RTNDT calculations. This information makes the lower circumferential weld (11-273) most limiting for RTNDT purposes and the development of Pressure-Temperature curves, even though the upper circumferential weld (10-273) is calculated to be most limiting for PTS considerations.

NOTES: (1) Values are specified for both End-of-License and August 1993 (in parenthesis). End-of-License values are based on
maximum anticipated 29 effective full power years of operation through July 10, 2010.
(2) Predicted "Shift in Reference Temperature (ARTFTS)" and "Adjusted Reference Temperature (RTPTs)" were calculated using Equations 1 and 2 in 10 CFR 50.61 (shown below). Equation variables are as noted in the table headings, above.
ARTPTs = (CF) f(0 .2 8 - 0.10 log f)
RTPTS = I + M + ARTPTs
