3.4.1.1 This specification is applicable in Mode 3 only.

4.4.1 The surveillance requirements will be deleted since the setpoints are automatically changed.

4.4.6.2d R. Martin requested definition of " steady state" for inspectability.

R. Bottimore will pursue.

3.4.7 No, closed Table 4.4.-1 OK, closed 3.4.8 The NRC is standardizing the specific activity limits to the values _ associated with the plant which has the most restrictive plant and site conditions.

Table 4.4.-2 Iten 4 b will be required by the NRC. TECo does not consider itself a /.sta gatherer for the NRC where significant safety issues have not been identified. Since this data is no longer.

required in Regulatory Guide 1.16 TECo does not understand why it is being added to these . technical specifications.

2.4.9 Need B&W input.

s-s 4.5.1 Open, TECo must show that a solution volume increase of > 2%

of tank volume could not reduce the boron concentration below the required concentration.

4.5.2 first part OK, closed second part OK, closed third part No, closed.

4.5.2 first part No, closed seccnd part No,,the NRC needs data to assure that the automatic Test Inserter circuit will be a reliable system.

'Til then, the NRC will give no credit for this system.

third part No, the NRC is looking for valves which cannot accept a single failure, fourth part OK, closed fifth part OK, closed 3.5.3 Open, R. Bottimore will pursue 3.5.4 No, closed Also the concenrxation limit in (D) is to be based on post LOCA B consideration.

P 3.6.1.1 No, when there is no fuel in the core, the NRC does not consider the unit to be in any mode.

4.6.1.1 No, closed 3/4 6.1.2. OK, closed 4.6.1.2a No, the 40 month period does not begin with the ILRT performed prior to Operating License 4.6.1.2f No, closed 4.6.1.2s OK, closed Table 3.6.-1 No, the telease location must be specified. TECo pointed out that in many cases the release location cannot be defined.

3/4 6.1.3 OK, La still required 4.6.1.3 No, the NRC interprets the law to require testing of air lock seals after each opening. While R. Bottimore agrees that this is unreasonable where m?ticiple entries are cencerned, the law must be obeyed. R. Martin suggested that the phrase "No detectable seal leakage..." was not inspectable.

4.6.5.4 OK except for surveillance frequency.

3/4.6.6 and 3/4.6.8 TEco to provide a technical specification combining these specifications to reflect system design. Also TECo to verify that tnere are no heaters upstream of filters.

3.6.7.1 Set point is OK.
