NOTE:
When performing step 4.4 apply torque to assembly body only. Do not apply torque to the Mumed Outlet.
4.4 Screw disc assembly into test fixture at Fike recommended torque level.
4.5 Pressurize disc assembly using air at a rate of no more than 50 psig per second to 25% of the stamped burst pressure @ 72 0 F. Hold pressure for 3 minutes. Check for leaks. If a leak is detected, record the pressure and stop test. If no leak, continue to step 4.6.
4.6 Continue pressurizing disc assembly to 50% of stamped burst pressure @ 72 0 F. Hold pressure for 3 minutes. Check for leaks. If a leak is detected, record the' pressure and stop test. If no leak continue to step 4.7.
4.7 Continue pressurizing disc assembly at a rate no more than 20 psig per second until burst.
Record burst pressure.
NOTE:
When performing step 4.8 apply torque to assembly body only. Do not apply toittue to the Mumed Outlet.
4.8 Remove the assembly from the fixture.
4.9 Mark both the disc assembly body and muffle outlet with a permanent marker using the same letter on each part.
4.10 Place the disc assembly base in a deep socket fixture tool. Identify original Fike torque range specified for securing the muffle outlet and procure proper torque wrench. Record information requested in step 4.2.
4.11 Remove muffled outlet from disc assembly. Record the torque required to break the cap loose from the base assembly. Mark the disc and ring with the same letter used in step 4.9.
Each disassembled disc set should be marked with a different letter group from the others.
4.12 Inspect the disc and record the following data.
4.12.1 'Ihickness (If the thickness varies then provide range of measurements).
4.12.2 Burst pattern,if unusual.
4.12.3 Outerdiameter.
4.12.4 Any visual physical phenomena not in conformance with the original shipping conditions (dents, scratches, stretch marks, corrosion appearance or other damage).

D-2 FUNCTION (S) l These solenoid valves function as a backup to the exhaust line drain pot steam trap. During
)
normal operation of the turbine using high quality steam, the drain path from the drain pot to the l
torus via the steam trap is adequate to remove condensate from the turbine exhaust line.
However, during turbine operation with low pressure and low quality steam (which is seen during HPCI surveillance testing during plant startup and as would be expected during HPCI operation during a small break LOCA), Condensate collects in the drain pot faster than it can be drained through the trap. Under these conditions, solenoid valve 1(2)-2301-32 opens automatically to drain to the gland seal condenser upon receipt of a signal from a drain pot level switch when the drain pot level reaches the high level alarm setpoint. A high level condition sounds an alarm in the control room.

I OMa-1988, Part 10, Paragraph 4.2.1.4(b)
" Power-Operated Valve Stroke Testing" "The stroke time of all power-operated valves shall be measured to at least the nearest second."
l OMa-1988, Part 10, Paragraph 4.2.1.8(e) l
" Stroke Time Acceptance Criteria"
" Valves that stroke in less than 2 sec may be exempted from 4.2.1.8(c) and 4.2.1.8(d) above. In such cases the maximum limiting stroke time shall be 2 sec."

OMa-1988, Part 10, Paragraph 4.2.1.9(h)
" Corrective Action"
" Valves with measured stroke times which do not meet the acceptance criteria of para. 4.2.1.8 shall be immediately retested or declared inoperable.. "
BASIS FOR RELIEF 10CFR50.55a(g)(6)(i), " impractical" These valves are not equipped with position indication and the valves are totally enclosed, so valve position cannot be verified by direct observation. Therefore. it is impractical to exercise and stroke time these valves in accordance with Code requirements.
Valve actuation may be indirectly verified by removing the HPCI system from service, filling the drain pot with water until the high level alarm is received, and observing that the high level alarm clears. It is impractical to assig,n a maximum limiting stroke time to these valves using this test method because the time for the alarm to clear would depend primarily on variables such as the rate of filling and the level of the drain pot when the filling is secured. The steam line drain pot is not equipped with direct level indication; therefore, the time required for the alarm to clear may vary significantly.
Failure of these valves to perform their safety function would be indicated by a drain pot high level alarm during operation with low pressure steam. Additionally, Condensate entrapped in the steam would cause significant fluctuations in exhaust steam header pressure.
Compliance with the quarterly exercising and stroke timing requirements of the Code would require either system modifications to replace these valves with ones of testable design, or to purchase non-intrusive test equipment and develop new test methods and procedures. These alternatives would be burdensome due to the costs involved.

Page 3 of 4 PROPOSED ALTERNATE TESTING Stroke times will not be measured, and corrective actions based on stroke time will not be i
implemented.
Because exercising the subject valves withot!t stroke timing provides no measure of valve degradation, a functional verification test is conducted on the drain pot level limit switches and the associated control room annunciators at least once every 90 days. Valve actuation will be indirectly verified by removing the HPCI system from service and by filling the drain pot with water until the high level alarm is received. Positive draining of the IIPCI drain pot will be indicated by a level increase in gland seal condenser and by the clearing of the high level alann.
