The 1.2 inch potential submergence in RB Volumes 15, 19 and 20 is considered insignificant and does not affect equipment located in these areas.5. There are four EQ components subject to potential submergence.
The submergence of these devices is acceptable as an evaluation shows that there is no impact on plant safety or shut down capabilities.

This table compares CLTP values for normal and accident dose to EPU values for normal, accident and Beta dose. The EPU TID is compared to the qualification TID.The CLTP normal dose rates provided in Table 2-5 were defined by routine radiation surveys. A more recent radiation survey provided the bases for the EPU normal dose values shown below. The EPU normal dose results were adjusted by the expected increase in radiation levels predicted for EPU operation.
In some cases these new surveys resulted in a reduction in normal dose for EPU. These radiation surveys are periodically performed to ensure that the normal dose is properly considered and remains accurate in the EQ files due to possible changes in plant configuration or operation.

Each of these inputs to the specified TID may be reduced for the AVCO solenoid manifold.
Since the solenoid manifold was only installed in 2009 and has a 20 year thermal qualified life, a reduced normal dose of 7.59E+06 is considered.
This dose is conservative to consider for normal use as it also includes increases due to extended power uprate which was not yet implemented in 2009. The manifold has a conservative I hour operating time, so the gamma accident dose is 5.68E+06.
The solenoid manifold is considered qualified for the specified unshielded 2.OE+08 Rad accident Beta dose because it can be shown that there is sufficient shielding around the sensitive materials to reduce the dose to 10%of Gamma qualification dose. Therefore, a modified TID applicable for the solenoid valve manifold becomes 1.327E+07 Rad. The AC solenoid valves were exposed to 2.55E+07 Rad and the materials of construction of the AC and DC solenoid valves are identical.
Therefore.

The revised Drywell gamma dose for 3 I-year normal life plus 180 day accident bounds the gamma dose of all other plant areas (includes 60-year normal dose plus accident gamma dose) and is bounded by testing.

Since the extended plant license expires in 2030 (September) and the valves were installed in 2009 (March), the remaining plant life is only of 22 years. Also, the installed SSPVs function (de-energize to vent) immediately upon a LOCA or tip to 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> under a HELB (manual reactor scram). Under the HELD3 scenario, no accident radiological dose will be experienced at the SSPVs. However, under a LOCA, there will be an accident dose contribution.
Per Regulatory Guide 1.89, qualification shall be established for one hour post-LOCA to demonstrate margin. Thus, reduced normal and accident doses can be used in the radiation qualification analysis.
The 22 year normal dose is 1.57E+05 Rad for either Reactor Building Volume 14 or 18. The 1-hour accident dose for either Reactor Building Volume 14 or 18 is 7.07E+04 Rad. As such, the total specified radiation dose for the SSPV installed in Reactor Building Volumes 14 or 18 is 2.28E+05 Rad. The test radiation exposure of 2.49E+05 Rad (minimum test level) bounds this value with additional margin.Page 33 of 96 L-MT-13-034 Enclosure 1 EPU EPU Title CLTP Normal CLTP Accident (Qualification Normal Dose Accident Dose Beta Dose Total EPU Qual.

The initiation of demineralized water and/or sodium pentaborate spray during a Design Basis Accident results in a harsh environment inside the Drywell (primary containment).
Table 2-6 demonstrates qualification of EQ equipment in the Drywell that is exposed to chemical spray conditions.

Spray Type Type 98-004-POI ASCO Solenoid Valves (50.49) Boric Acid Demin Water/Sodium Pentaborate A downward pointing street elbow is required on the exhaust port for valves potentially exposed to spray. However, there is only one solenoid valve installed in the Drywell that is qualified by this EQ File that would be subject to spray. Drywell spray is used during design basis LOCA. Under that scenario, this valve will function within 5 minutes. Drywell spray is not initiated until after 10-minutes (after LPCI injection is complete).
Therefore, this solenoid valve does not require exhaust port protection for spray. In summary, no valves qualified by this PQE require exhaust port protection.
98-004-P03 ASCO Solenoid Valves (50.49) Boric Acid Demin Water/Sodium 9.5 to 10.5 7 to 8.58 See below Pentaborate I Of the valves qualified by this PQE, only the SRV Pilot solenoid valves are exposed to spray as they are located in the Drywell. During testing, the vented exhaust ports of the specimen valves were protected from direct impingement of spray. The exhaust ports were configured with downward facing street elbows.As installed, only the exhaust ports of eight solenoid valves require spray protection.
The exhaust ports of the remaining solenoid valves in the Drywell are piped to the other SRV solenoid valves and are thus inherently protected.
98-008-POI Automatic Valve Company (AVCO) Deionized Water Demin Water/Sodium N/A 7 to 8.58 See below Air Control Assembly (50.49) Pentaborate The spray at Monticello is manually controlled and not automatically initiated under any event. Procedural guidance directs operations to only use spray after the first 10-minutes of a design basis LOCA (after LPCI injection is achieved).
Therefore, the MSIV solenoid cluster will be de-energized prior to being subject to spray. The 20 minute demineralized water spray of the test sufficiently bounds the plant spray conditions.

The cable specimens were not subject to spray during the test. The Drywell spray is not expected to have any detrimental effect on the XLPE insulation based on the submerged IR testing conducted post-LOCA.

During other emergency environmental testing, GE subjected the various penetration designs to steam/submergence.
The test assemblies were subjected to steam and submerged and no detectable leakage was observed.
In two tests, one end of the test penetration was submerged.
In another two tests, the entire assembly was submerged.
The sensitive materials of the penetrations, excluding the cables (qualified per EQ File 98-017), is epoxy. Material analysis reveals that epoxy resins have broad chemical resistance.
Therefore, it is reasonable to conclude that the epoxy would not be affected by a slightly basic water/sodium pentaborate spray. In addition, the epoxy is coated with Hypalon paint for more protection.
Therefore, the GE EPAs are qualified for the Drywell spray.98-025-POI Limitorque Motor Operators (DOR) Boric Acid Demin Water/Sodium 7.67 7 to 8.58 See below I IPentaborate The test spray conditions sufficiently bound the specified spray conditions.
The motor qualified in this EQ File has no T-Drains, thus Drywell spray is not expected to migrate into the motor housing. It is further observed that Drywell spray will only commence after the first 10-minutes of inside Drywell accident conditions.
The longer operating time demands for valve closure are due to outside Drywell HELB events during which time there will be no spray inside the Drywell.98-026-PO1 Limitorque Motor Operators (50.49) None Demin Water/Sodium N/A 7 to 8.58 See below Pentaborate A test anomaly as documented in the test resulted in the flooding of the test actuator with water such that the actuator components became submerged during the testing. A post-test inspection revealed water inside the motor. Additionally, similarly configured Limitorque valve actuators were subjected to PWR containment type testing with spray as documented in a separate test report. Based on the discussions in this test, it is evident that valve actuator specimens were subject to bounding spray conditions.
One MOV has a replacement aluminum cover to support ease of maintenance at its confined location in the Torus compartment (minimize rigging required if the original cast iron cover was used). Limitorque cannot support chemical spray qualification for this actuator based on testing. However, this is not a concern for the MOV located in the Torus as it will not be exposed to spray conditions.
Therefore, the test specimens have demonstrated the ability to perform their safety function under the postulated spray at MNGP.98-032-P02 I Namco EA740/EA 180 Limit Boric Acid/Water Demin Water/Sodium 10.5 7 to 8.58 See below Switches (50.49) [ Pentaborate The test specimens were exposed to a chemical spray conditions consisting of 3000 ppm boron buffered to a pH of 10.5 with sodium hydroxide.

Page 39 of 96 L-MT-13-034 Enclosure 1 Humidity The Reactor and Turbine building ambient relative humidity is assumed to be 20% to 90% during normal plant operation.
The Reactor and Turbine building accident relative humidity is assumed to be 100% in environments where a HELB changes either the normal pressure or temperature.
These assumptions are the same for both CLTP and EPU accident conditions.
Normal Temperature The Drywell was evaluated and no change in normal temperatures for EPU was indicated.
For general areas of the Reactor Building, there was no increase of significance in normal ambient temperature noted. As such, there is no impact of EPU conditions on normal plant temperature inputs to qualified life assessments.
All EQ equipment is qualified to the normal ambient conditions in which it is located and the normal ambient temperatures are not expected to increase due to EPU.Page 40 of 96 L-MT-13-034 Enclosure 1 NRC Request No. 3 Please modify Figures 27-1 and 27-2 to include the profile of the qualification level of EQ equipment to show that the EQ equipment will remain bounding under EPU conditions.
