RESPONSE
TO R.
C. LEWIS'ETTER DATED NOVEMBER 8 j 197 9 R REFERENCE RII RFS 50-259/79-27, 50-260/79-27$
50-296/79-27 Appendix A of the referenced letter identified two items which were apparently in noncompliance with NRC requirement's.
The following are those items and our response.
'nfraction A.
As required by Technical Specification 6.3.A, detailed written procedures shall be prepared,
- approved, and adhered to.
Mechanical Maintenance Instruction 1 states that the steam separator will be transported from the vessel to its storage pit under water.
Radiation Control Instruction 1 states that the Health Physics supervisor's approval is required for dose rates to workers which exceed 1 Rem per hour.
Contrary to the above, on August 28, 1979, the steam separator was transported from the reactor cavity to its storage pit with the top four to six feet uncovered.
Dose rates to workers were 1.5 Rem per hour during part of the movement and the Health Physics supervisor's approval was not obtained.
This is an infraction applicable to unit 3.
~Res esse Corrective Ste s Which Have Been Taken and Results Achieved Mechanical Maintenance Instruction 1 has been revised to clarify the procedure r
for transferring the moisture separator from the reactor vessel to the equip-ment pit.
The revised procedure allows for the transfer of,the separator to the equipment pit partially submerged if sufficient water is not available within a reasonable time to fillthe reactor well.
However, revisions have also been made to provide proper warnings that a radiation hazard may exist and that precautions are necessary to minimize exposure to personnel.
l
Corrective Ste s Taken to Avoid Further Noncom liance A precaution will be added to the maintenance instruction to check the path clear for the transfer of the moisture separator to the equipment storage pit.
Date Full Com liance Achieved Full compliance was achieved on September 25, 1979.
Su lemental Information During the moisture separator, transfer on August 28, 1979, the personnel had to enter a 1.5 Rem per hour field when the moisture separator became entangled with an,air hose leading to the main steam line plug.
This air f
line had to be untangled from the moisture separator before the separator could be safely moved to developed, the dose rate reduce exposure rates.
Had-this problem not to workers would have been below 1 Rem per hour.
Infraction B
As required by 10 CFR 73.55(e)(6), individuals not authorised by the licensee to enter protected areas without escort must be escorted in the, protected areas by a watchman or other individual designa'ted by licensee.
As implemented by Paragraph 1.7 of the licensee's approved Security
- Plan, the Plant Superintendent will assign trained plant personnel to perform necessary escort duties.
h Contrary to the above, on September 5, 1979, two individuals were observed in the Outage office, within the protected area, without an escort assigned "or present.
l This is an infraction.
~Res onse Corrective Ste s Taken and Results Achieved An escort had been assigned to these two TVA employees but had left the area.
1'hen the deficiency was identified, the person assigned as the escort was reeducated concerning his responsibilities as an escort.
Corrective Ste s Taken To Avoid Further Noncom liance Reeducation of, this individual should ensure no further noncompliances in this area.
Date Full Com liance Achieved
~', Full compliance was achieved on September 5, 1979.
