MILLSTONE POWER STATION UNIT 3 RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION LICENSE BASIS DOCUMENT CHANGE REQUEST (LBDCR) 3-01-03 SELECTIVE IMPLEMENTATION OF THE ALTERNATIVE SOURCE TERM -

FUEL HANDLING ACCIDENT ANALYSES By a letter dated March 4, 2003, Dominion Nuclear Connecticut, Inc. (DNC) proposed to amend Operating License NPF-49 by incorporating changes into the Millstone Unit 3 Technical Specifications. The proposed changes would selectively implement the Alternative Source Term for the Fuel Handling Accident analysis.

Inconference calls with the Nuclear Regulatory Commission (NRC) during the weeks of January 6, 2004 and February 2, 2004, the NRC staff requested modifications to the proposed Technical Specification changes in the March 4, 2003 letter.

The NRC staff specifically requested the following modifications:

1. Technical Specification 3/4.7.7, "Control Room Emergency Ventillation System" Change the proposed Applicability from APPLICABILITY: MODES 1, 2, 3, and 4 To APPLICABILITY:-MODES 1, 2,3,4,5,and 6

2. Technical Specification 3/4.7.8, "Control Room Envelope Pressurization System" Change the proposed Applicability from APPLICABILITY: MODES 1, 2, 3, and 4 To APPLICABILITY: MODES 1, 2, 3, 4, 5, and 6 AnO\~

Serial No.04-072 Page 2 of 4

3. Technical Specification 3/4.9.4, "Containment Building Penetrations" Change proposed Action a. from

a. The equipment access hatch closed or capable of being closed under administrative control, To

a. The equipment access hatch shall be either:

1. closed and held in place by a minimum of four bolts, or

2. open under administrative control and capable of being closed and held in place by a minimum of four bolts, Additionally, the following Bases changes are added:

1. MODES 5 and 6 are added in the discussion of Actions d. and e. in Insert D to page B 3/4 7-12, and Actions e. and f. in Insert E to page B 3/4 7-18.

2. The wording "CORE ALTERATIONS" on page B 3/4 7-13 is deleted. This deletion is consistent with the deletion proposed in Technical Specification 3/4.7.7, Actions d. and e. contains the marked-up version of the appropriate pages of the current Technical Specifications. Attachment 2 provides the retyped pages of the Technical Specifications. Attachment 3 provides an informational copy of the proposed changes to the Technical Specification Bases.

The additional information provided in this letter will not affect the conclusions of the Safety Summary and Significant Hazards Consideration discussion in the DNC March 4, 2003, letter.

If you have any questions or require additional information, please contact Mr. David W.

Dodson at (860) 447-1791, extension 2346.

LIMITING CONDITION' FOR OPERATION Two independent control room emergency air filtration systems are required to be operable to ensure that at least one is available in the event the other system is disabled; A control room emergency air filtration system is.OPERABLE when the associated:

a. Fan is OPERABLE;

b. HEPA filters and charcoal adsorbers are not excessively restricting flow and are capable of performing their filtration functions; and

c. moisture separator, heater, ductwork, valves, and dampers are OPERABLE, and air circulation can be maintained.

The integrity of the control .rooni habitability boundary (i.e, walls, floors,.ceilings, ductwork, and access doors) must be maintained .such that. the control building habitabilityzone can be maintained at its design positive pressure if required to be aligned in the filtration pressurization mode.

However, the LCO is modified by a footnote allowing the control room boundary to be opened intermittently under administrative controls. For entry and exit through doors the administrative control of the opening is performed by the.

person(s) entering or exitingthe area. For other openings, these controls consist of stationing a dedicated individual at the opening who is in constant communication with the control room. This individual will have a method to rapidly close the opening when a need for control room isolation is indicated.

ACTION MODES 1. 2. 3. and 4

a. With one control room emergency air filtration system inoperable, action must be taken to restore the inoperable system to an OPERABLE status within 7 days. In this condition, the remaining control room emergency air filtration system is adequate to perform the control room protectibn function. However, the overall reliability is reduced because a single failure in the OPERABLE train could result in a loss of the control room emergency air filtration system function. The 7-day, completion time is based on the low probability of a DBA occurring during this time peri.od, and the ability of the remaining train to provide the required capability.

If the inoperable train cannot be restored to an OPERABLE status within 7 days, the unit must be placed in at least HOT STANDBY within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months .

During the period that the., control room boundary is inoperable, appropriate compensatory measures (consistent with the intent of GDC 19) should beutilized to protect control room-operators from potential hazards such-as radioactive contamination, toxic chemicals, smoke, temperature and relative humidity, and physical security. Preplanned measures should be available to address these concerns for intentional and unintentional entry into this condition. The 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months allowed outage time is reasonable based on the low probability of a DBA occuring during this time period, and the use of compensatory measures.
