SUBJECT:
Dear Mr. Reid:
The U.S. Nuclear Regulatory Commission recently received information concerning deficiencies associated with the augmented offgas system at the Vermont Yankee Nuclear Power Station. This system is important because it is a control process for minimizing radioactive effluents and radiation dose at the site boundary during normal operations. More details are enclosed for your organization's review and follow-up. This information was discussed telephonically on January 11, 1996, between Mr. R. Conte of my staff, you and Mr. R. Wanczyk of your staff. As a result of this discussion, it is our understanding that you have chartered a review team to look into this matter.
We request that the results of your review and disposition of this matter be submitted to Region I within 30 days of the date of this letter. If more time is needed for your review, a status report within 30 days of this letter will be acceptable along with a date on when the final report will be submitted to us. We expect that your evaluation of this matter will be thorough, objective and of sufficient scope and depth to resolve this matter.
The information was from an anonywous source and forwarded to us by the New England Coalition on Nuclear Pollution, Inc. who also made the information publicly available as noted in several media reports on the matter. As such the information does not need to be exempt from public disclosure. However, we request that your response contain no personal privacy, proprietary, or safeguards information so it can be released to the public and placed in the NRC Public Document Rooms. If necessary, such information shall be contained i in a separate attachment, appropriately marked, which will be withheld from public disclosure. The affidavit required by 10 CFR 2.790(b) must accompany l
your response if proprietary information is included.

ENCLOSURE The Nuclear Regulatory Commission (Region I Office) received information relatad to deficiencies associated with the advance offgas (A06) system at the Vermont Yankee Nuclear Power Station. Specifically:
[ 1. The advanced offgas system has been allowed to deteriorate over the t: years; and, as a result, the plant is discharging illegal amounts of l
radioactivity.
- 2. In order to save money, plant managers cancelled a plan by the engineers to refurbish the system during the 1995 refueling.
- 3. The engineers that spoke out against the cancelling were punished and had a bad report inserted in their personnel file.
- 4. Recently the offgas system was declared out of operation because critical monitoring equipment was not calibrated properly. This condition existed for many years.
NOTE: With respect to item 4, a preliminary review by NRC inspectors of recent calibration problems on the hydrogen monitor for the A0G system indicated that the problem is related to an error in the plant's Technical Specifications (TS). This review will be documented in NRC Inspection Report No. 50-271/95-25 as an unresolved item; but, in this response, we request the following additional information:
- a. - Your perspective on the calibration problem with the hydrogen monitor, how long the problem existed, and the root cause of the TS error along with corrective actions. Also, provide information on when a license amendment will be submitted for NRt. staff review.
- b. Provide information on any other critical monitoring equipment that is or was inoperable since the last refueling outage along with root cause and corrective actions taken or planned.
- 5. The vice president at Yankee Atomic (YAEC) knows about this, but has done nothing because.it would affect the recent organization changes -
he knows it could affect his job if he had to tell Vermont Yankee managers that they were not operating the plant correctly.
In addressing the above items your response should include:
- a. Current status of the offgas system, including any outstanding work requests .and planned modifications (items 1, 2, and 4 above)
- b. Summiary of any known recent (since the last refueling outage) offgas system problems by plant staff or as documented in Vermont Yankee Event Reporting System along with completed or planned resolutions (items 1, 2, and 4 above).
c -
'e 2
l
- c. Basis for postponement or cancellation of preventive / corrective maintenance or any modifications to the offgas system from the 1995 outage (items 2 and 3).
- d. Provide details on any management / personnel disciplinary actions completed or planned associated with decisions related to the offgas system, and its modifications, since the last refueling outage (itent 3 and 5 - 10 CFR 2.790 information may need to be segregated in the response).

De3r H dthe l I must report to you a. serious violation of HRC requirements at Vermont l Yankee.
Tbc advanced offgas system has been allowed to deteriorate over the years and -
s a result the plant is discharging illegal amounts of radioactivity.
- To order to save money plant managers cancelled a plan by the engineers to l -refurbish the system during the 1995 refueling.
l The er.gineers that spoke out against the cancelling were punished and had a I bad rep 0rt inserted in their personnel file.
Recently the offgas system was declared out of operation because critical monitoring equipment was not calibrated properly. I am told this condition
- has existed for many years.
The vice president at Yankee Atomic (YAEC) knows about this, but has dcle nothing because it would affect the recent organization changes - he knows it could affect his job if he had to tell Vermont Yankee managers that they were i
l not operating the plant correctly.

Dear Mr. Reid:
This refers to the routine safety inspection conducted by Dr. Jason C. Jang of this of fice free october 30-November 3, .1995, of a :tivities authorized by NRC License Number DPR-28 at the Vermont Yankee Nuclear power Station, Vernon, Vermont, and to the discussions of our findings held by Dr. J. C. Jang with Mr. G. Maret and others of your staff at the conclusion of the inspection.
Areas exaeined during this inspection, involving your radioactive offluent control prograss, are important to public health and safety and are discussed-in the Mac Region I inspection report that is enclosed with this letter.
Within these areas, the inspection consisted of selective examinations of procedures and representative records, interviews with personnel, and observations by the inspector.
Within the scope of this inspection, we noted that you maintained' effective
-programs for radioactive liquid and gaseous effluent control sufficient to protect the public health and safety and the environment. We noted further that the responsible individuals _in the Chemistry Department had maintained their knowledge, qualifications, and expertise relative to'these programs. No safety concerns 'or violations of NRC requirements were identified in your program.
No reply to this letter is required._ Your cooperation with us in this statter

3 5.0 RADIOACTIVE LIQUID AND CASEOUS EFFLUENT CONTROL PROGRAMS The inspector toured the plant and reviewed the following licensee procedures and radioactive liquid and gaseous discharge permits to determine the implementation of the Ts and the off-site Dose calculation Manual (ODCH) requirements:
- Procedure OP 2610, Liquid Waste Disposal,
- Procedure OP 2611, Caseous Radwaste, e Procedure OP 2612, Burning of Radioactively-contaminated Waste oil, and e Procedure OP 4609, Periodio Evaluation of Off-Site Radiological Doses.
During discussions with the licensee regarding the radioactive liquid effluent control practices at the site, the inspector noted that tho licensee processed and recycled the liquid radwaste. There were no radioactive liquid releases during'1994 and 1995 as a result of this programs and, therefore, no radioactive liquid release permits were issued. The inspector noted that the responsible individual from the Chemistry Department continued to work with the Operations Department and contractors during the refueling outage to monitor chemical intrusion to the RCA. The licensee operates the radioactive liquid radwaste systems efficiently and recycles all water, i.e., with no direct discharges to the river. The licensee's goal is to minimize or eliminate routine radioactive liquid releases from the site during normal operation.
Dur'ing this inspection, the inspector noted that the new main sta_ck noble gas detectors were installed and readout (output) instrumentations were upgraded, from 6-decade-log meters to digital readout meters. It is expected that the use of digital meters for calibrations and routine readings will enhance the accuracy of the monitoring results. Through review of gaseous effluent permits, the associated procedures, and discussions with the licensee regarding radioactive gaseous effluent control program, the inspector determined that the licensee implemented the program effectively.
The chemistry Department has the responsibility to conduct the effluent control programs, as aforementioned in Section 3.1 of this inspection report.
During discussions with the members of Chemistry Department, the inspector noted that the responsible individuals had excellent knowledge in the areas of (1) radioactive liquid and gaseous effluent controls, (2) quantifying the total amount of gaseous effluent release using the radiation-monitoring systems, and (3) protection of the public health and safety and the environment.
Based on the above reviews, the inspector determined that the licenses had conducted excellent radioactive liquid and gaseous effluent control programs.
The inspector aleo noted that the licensee's management supported the effluent control programs, and the chemistry staff continually reviewed its effluent control programs vigorously with a view toward improvement.

4 7.0 Cf.LIBRATION OF EFFLUENT /PR0dESS RADIATION-MONITORING SYSTEMS (RMS)
The inspector reviewed the most recent calibration results for the following effluent / process monitors:
- Liquid Radwaste Discharge Monitor 8 Service Water _ Discharge Monitor 8
e Rein Stack Noble Gas Monitor (Normal and High Range Augmented Offgas (AOG), Building Noble Gas Monito The Isc Department had the responsibility to perform electronic calibrations for the above RMS. Th1 Chemistry and Radiation Protection Departments had the l
responsibility to perform radioloolcal calibrations.) All reviewed A calibrations were performed at the required frequencies, and results were )
I within the licensee's acceptance criteria,---
During the previous inspection conducted in November 1994, the inspector was informed that the RMS uparade croinct for the_ main mtack and Anc-mnnitorino systems, including replacement of ths 6-decade logarithmic scale with digital readoute in the control room, would be completed during 1995 refuel outage.
This upgrade project was completed during the 1995 refuel outage. The licensee performed the primary and the secondary calibrations for these RMS. l The inspector reviewed the calibration results, which were within the licensee's acceptance criteria. The inspector noted that the licensee used a statistical method (i.e., linear regression method) to determine the linearity.
Based on the above reviews, the inspector determined that the licensee had an
' effective calibration program for the effluent / process monitors.
8.0 AIR-CLEANING FYSTEMS The inspector reviewed the licensee's most recent surveillance results as part of the examination of the implementation of the technical specification requirements for the standby gas treatment system.
e Visual Inspections l
8 In-Place HEPA Leak Tests 8 In-Place Charcoal Leak Tests l

9.0 YANREE ATOMIC ENVIRONMENTAL LABORATORY (YAEL)
A part of thic inspection, the inspector visited the licensee's effluent analytical contractor laboratory (YAEL). The inspectors (1) toured the YAEL facilities and observed laboratory activities including semple processing, (2) held discussion with the YAEL technical staff, and (3) reviewed selected procedures and quality assurance / control programs.
The inspector noted that the responsible individuals had excellent knowledge in the areas of (1) origin of the radioactive liquid and gaseous effluent samples, (2) analytical technique, (3) importance of quality assurance / control, and I (4) protection of the public health and safety and the environment.
Based on the above reviews, the inspector determined that the YAEL conducted excellent affluent samples analyses and quality assurance / control programs.
The inspector had no further questions.
10,0 EXIT INTERVIEW '
The inspector net with the licensee representatives denoted in section 1.1 of this inspection report at the conclusion of the inspection on November 2, 1995, at the Vermont Yankee site.
