Item: 3/4.6.1.7 Containment Ventilation System Surveillance 4.6.1.7.2 is not appropriate for the Millstone Unit 3 design.

P NNECO RESPONSE Surveillance

• requirement 4.6.1.7.2 requires that the'42 inch containment purge and exhaust butterfly valves be leak tested at Pa every 6 months. It has been NNECO's position that replacement of the seals in these valves every two cycles would make 6 month testing unnecessary. This alternative was proposed to avoid the difficulties associated with testing these valves at Pa during ooeration.

Another alternative to leakage testing at Pa would be testing at a reduced pressure '

every 6 months. The results from _the reduced pressure tests would be projected to leakage at Pa using the correlation proposed in 10 CFR 50 Appendix 31.e., Lt = La (Pt/Pa)h. A one time back-to-back set of tests at Pt and Pa would be run to demonstrate the validity of this correlation.' If Ltm/ Lam ) 0.7, the correlation equation prese4ted above (based on the Darcy equation and the assumption of turbde'nt flow, i.e., orifice-like flow) would be substantiated. A reduced pressure (Pt) of E Pa wculd be selected to be consistent with Appendix 3.

5

. Thus, NNECO pr'o poses reduced pressure testing under the following conditions:

Leak test the subject valves at- Pt : 34.4 PSIA (19.7 PSIG) once every 6 months.

[

Project leakage measured at Pt to an-equivalent leakage at Pa using the equation Lt = 0.707La.  ;

Perform a one time correlation of leakage at Pt a'nd l ia by means of back-to-back tests. Use the relationship Ltm/ Lam > 0.7 to justify continued use of the proposed correlation equation.

See attached specification. '

Item: Justification for Action Statement 2c Table 3.3 - Three Loop Values NNECOs RESPONSE In standard Technical Specifications Action Statement 2c of Table 3.3-1 limits power to 75% RTP and reduces the Power Range Neutron Flux Setpoint to 85% in four loop operation with an NI Power Range Channel out of service. With one Power Range out of service in three loop operation the Thermal Power and Power Range High Flux Trip setpoints should be reduced by the same ratio as in four loop operation.

In three loop operation, power is limited to 65% RTP and the Power Range High Flux Trip Setpoint is 80% With a detector out of service in three loop operation, power should be limited as follows: .75 x 65% = 48.75% Rounding off to the nearest 5% yields a value of 50% PTP.

The Power Range Neutron Flux trip setpoint should be reduced as follows:

Four Loop Three Loop 85 % = X 109 % 80 %

X = 62.38%

Rounding off to the nearest 5% results in a Power Range Neutron Flux Trip Setpoint of 605
