SUBJECT:
ENFORCEMENT CONFERENCE RELATIVE TO NRC INVESTIGATION 1-93-021R i
i
Dear Mr. Reiter:
1 l This letter refers to the investigation conducted at the Salem Nuclear
- i Generating Station by Ms. K. L. Monroe of the NRC Office of Investigations i l
(01) Field Office, Region I. The purpose of the investigation was to l 3
determine whether certain activities authorized by the licensee were conducted i in accordance with NRC requirements. A copy of the synopsis of the i
l investigation is enclosed. ]
!' Based on the findings of the investigation, apparent violations were l l
identified and are being considered for escalated enforcement action in '
accordance with the " General Statement of Policy and Procedure for NRC '
- Enforcement Actions" (Enforcement Policy), 10 CFR 2, Appendix C (copy
! enclosed). The apparent violations involve 10 CFR 50.5 (Deliberate
{ misconduct) and 10 CFR 50.7 (Employee protection). 10 CFR 50.5 prohibits I
> licensee employees from engaging in deliberate misconduct that causes the licensee to be in violation of any rule or regulation; and 10 CFR 50.7 l
j prohibits the licensee from discriminating against any employee for engaging f in certain protected activities. The investigation indicates that three i former Salem senior managers, including yourself, took deliberate action that .
j involved discrimination against two Safety Review Group (SRG) engineers who t
- were engaged in protected activities on December 3, 1992. As an agent of the j licensee, your acts caused the licensee to be in apparent violation of the
! requirements of 10 CFR 50.7.
1 l Specifically, on December 3,1992, two SRG engineers attempted to process a j safety issue, in accordance with station procedures, by submitting an incident j report (IR) to the General Manager-Sales Operations (GM), and the Operations -
l 1 Manager (OM). The IR questioned the safety-related qualification of l commercial grade air supply pressure setpoint regulators, which control ;
l j service water flow to the containment fan cooling units. In conversations i with the SRG engineers, the GM (with various cooperation and advice of the OM) ,
i told the individuals to get out of his office and threatened to have them
! removed from the site, an action that was interpreted by the SRG engineers as
! harassing and intimidating. Upon deliberation, the GM wrote a memorandum to j you, the then General Manager-Quality Assurance and Nuclear Safety Review (GM-QA/NSR), requesting you to have the engineers removed from any direct involvement with Salem station. Subsequently, further apparent discriminating action was directed against the individuals when you deliberated and took .
action to ' reprimand and counsel the SRG engineers relative to their submittal of the IR and handling of the situation. In conclusion, the NRC investigation 9701300128 970124 PDR FOIA O'NEILL96-351 PDR

Attachment 2 Chronology Of POPS Evaluation By PSE&G j March 15, 1993 Westinghouse issues NSA-93-005B on cold overpressure i mitigation system nonconservatisms
!' July 26, 1993 NRC Infomation Notice 93-58, "Nonconservatism In Low-Temperature Overpressure Protection For Pressurized-Water
- Reactors," is issued.
December 30, 1993 PSE&G memo MEC-93-917 recommends restricting the number
] of RCPs in operation, while in Mode 5, to no more than two RCPs. The memo takes credit for ASME Code Case N514 and closes the ATS item on NSAL-93-0058.
April 19, 1994 Discrepancy Evaluation 94-0060 was initiated after it was
, recognized that NRC approval is necessary for use of the
! Code Case. Memo points out that even with 1 RCP
- operating in Mode 5, the existing POPS analysis shows a calculated peak pressure in excess of the Technical
! Specification limit. Memo also points out that the plant i design basis relies on one PORV set at 375 psig, and that l with the current plant configuration the RHR relief valve (RH3) would be available to mitigate LTOP transients. [
! PSE&G did not consider the DEF an operability concern, taking credit for the Code Case. DEF recommends either i getting the Code Case approved for use at Salem by the NRC or, completing the calculations for LTOP using the j RH3 valve and revising the plant design basis, i May 26, 1994 PSE&G memo MEC-94-630 was issued, superseding MEC-93-917, and dispositions the issue based on an assessment that did not account for the setpoint error introduced by RCPs [
running during the mass addition transient. Interviews with licensee personnel indicate that because operation -
of a RCP when RCS is water solid is precluded procedurally, the mass addition transient analysis did not account for the setpoint error associated with running RCPs. On this basis, the memo recloses the ATS item for the NSAL.
June 29, 1994 During the evaluation of an unrelated DEF by a different department, the licensee determines that the Configuration Baseline Document for CVCS contains an error concerning control of the positive displacement charging pump. The document incorrectly states that the PDP is tripped by an SI signal. If the PDP is running when the SI signal is initiated, and offsite power is available, the pump will not trip. In addition, engineering review had detemined that trip signals to the PDP will be blocked until the SI signal is reset. .

i
' Attachment 2.
September 27, 1994 Problem Report No. 940927126 was initiated when a new worst case scenario was identified, during efforts to take credit for RH3. The scenario is: RCS in Mode 5 with i a pressurizer bubble and one RCP running; then an
- inadvertent SI signal starts the centrifugal charging i pump, collapses the bubble, and the RCP continues to run.
The PR recognizes that the current design basis transient is not plausible and provides analysis showing the new 1
worst case scenario results in acceptable peak pressu: t s.
The PR states that PSE&G will pursue revising the current plant design basis and also seek a license change to take credit for RH3 (to add margin for future revisions of the PT curve limits). The PR requests that the Code Case '
approval be sought, to alleviate infringement on the current design basis without reanalysis.
September 28, 1994 PSE&G meno NLR-194900 requests engineering provide additional analysis. The licensing engineers recognize that analyses have relied on the use of two PORVs and RH3 to mitigate the transient (two out of three valves would provide sufficient relief and meeting single failure criterion). Memo also questions new worst case not i starting with a water solid RCS. Issue left open pending .
further engineering analysis and plans are made to apply for a license change (add RH3 to TS) and approval of the Code Case for both Salem units.
November 17, 1994 PSE&G initiates Incident Report No.94-419 and makes a 10CFR50.72 notification for Unit 1 being in an unanalyzed condition. The licensee recognizes that the PDP design discrepancy effects their analysis for POPS. The '
additional mass input from the runn'ing PDP causes a peak '
pressure for the mass addition transient of 474 psig.
This analysis was for a single PORY (due to single failure considerations) since no licensing action had been taken to have RH3 included in the design basis.
From a safety perspective: the licensee has three valves available, any two of which will mitigate the effects of an LTOP transient.
